with neovascular AMD in one eye, receiving oralDHA (840 mg/day) or placebo over 3 years, for which the assessment of incident CNV in thefellow eye is the primary efficacy endpoint. 300patients were enrolled prospectively in a singlecentre at the Department of Ophthalmology atthe Hôspital Intercommunal de Créteil (Créteil,France). Subjects were examined at baseline, 6 months, 1 year, 2 years, and 3 years, end-visit.The following examinations were performed ateach visit: • Best-corrected visual acuity, intra-ocular

pressure, slit lamp examination, fundusphotography, and fluorescein angiography

• Multifocal ERG (electro-retinography) wasperformed at baseline and at the end-visit

• Changes in plasma lipoproteins, serum andred blood cell membranes (RBCM) EPA andDHA content were also determined as well as genotyping of apoE, an accepted genetic lipid-risk marker of AMD

• Safety was assessed by determining ocularand systemic tolerance to study treatment andincluded slit lamp examination, evaluation oflens opacity and measurement of IOP

Final results of the study will be available shortly.

CARMA StudyThe recent CARMA study1,2 was presented by Dr. John Nolan of the Macular Pigment ResearchGroup, Waterford Institute of Technology,Waterford, Ireland. A Bausch & Lombsupplement containing lutein and zeaxanthinwas tested in the CARMA study, conducted byleading researchers at Queens University,Belfast, and the Waterford Institute ofTechnology. The CARMA study is a high qualitystudy testing supplementation with carotenoidsin patients with early AMD.

The results showed that the intake of theCARMA supplement preserved the quality ofmacular pigment. According to the outcomes ofthe study, the macular pigment of participantswho were assigned to placebo, declinedsteadily, whereas a modest increase in themacular pigment of the intervention group wasobserved. Beneficial effects on visual functionwere observed with increasing levels of serumlutein in CARMA study participants.

The CARMA study was conducted betweenOctober 2004 and March 2008, 433 participantsof average age 77 years were enrolled in thetwo study sites. Professor Chakravarthy and Dr.Stephen Beatty, both of whom are recognisedretinal specialists, led the study in theirrespective centres.

GEMO Conference 2009, Nice,France hosted by Bausch & Lomb

“I enjoyed the GEMOone day meetingvery much. It waswell organised withpresentations in bothFrench and English,and with superb livetranslations into bothlanguages.”

G.E.M.O (Groupe d’Experts en Micro-nutritionOculaire) is a panel of experts, comprised ofkey opinion leaders in ophthalmology,nutrition and epidemiology, who assess thecurrent evidence for ocular nutrition andapply it pragmatically to patient care.

“I enjoyed the GEMO one day meeting verymuch. It was well organised with presentationsin both French and English, and with superblive translations into both languages.

The scientific content was extremely good,with lectures covering the role of Omega-3fatty acids in physiology and with respect toAMD. Results from the CARMA carotenoidsupplementation trial were presentedsuggesting that lutein is definitely worth takingin AMD in addition to the AREDS formula.

By the end of the meeting I felt that we arestill in the process of unravelling thecomplex micro-environment in the retina butthat progress is being made. We should soonbe in a position to make recommendationsto patients about which nutrientsupplements are really worthwhile takingand which are not. Ultimately, we need tomove towards a programme of prevention ofAMD, and groups such as GEMO have a realcontribution to make towards this.”

Mr. Nigel DaviesConsultant Ophthalmologist, Chelsea & Westminster Hospital

Omega-3 fatty acidsThis was a key topic of the 2009 congress. Dr. Pascale Barberger-Gateau, Head of theEpidemiology Department at Victor SegalenUniversity in Bordeaux, presented recent datademonstrating the benefits of omega-3 insupporting human cognition and managingdepression.

Professor Eric Souied, Consultant Ophthalmologistat Creteil Hospital, France, presented preliminaryresults of the recent NAT-II study demonstratingthat supplementation with omega-3 fatty acidscan help in preserving sight.

The NAT-II study is a double-blind, prospective,randomised, parallel, comparative trial in patients

CONGRESS REVIEW 05

"AMD cannot be cured yet, but our presentstate of knowledge suggests that a high intakeof lutein and zeaxanthin can have a positiveimpact on the prevention of the disease.Therefore, the eye specific carotenoids are a central topic in AMD research. The results of the CARMA study show that a daily intakeof 12mg lutein and zeaxanthin, together with co-antioxidants, preserves the quality of themacular pigment and had beneficial effects on visual performance and morphologicalprogression of the disease.“

AMD the facts…• Age-related Macular Degeneration

(AMD) is an eye condition affectingthe macula, which is responsible forthe sharp, central vision needed forseeing objects clearly

• AMD is thought to affect up to half amillion people in the UK today, andoccurs in two forms – dry and wet

• Dry AMD is the most common,affecting 90% of all sufferers. It generally affects both eyes, butvision can be lost in one eye whilethe other seems unaffected

• Wet AMD is an advanced stage ofAMD, and occurs when abnormalblood vessels start to grow underthe macula, leaking fluid anddamaging it. With AMD, loss ofcentral vision can occur quickly

Who could have guessed that the abovesimple question, posed by a medical studentin 1948, would have been so instrumental inchanging the way cataracts were treated for ever?

However, this is just what happened whenStephen Perry, a medical student at St Thomas’Hospital in London, having observed Sir HaroldRidley completing a standard cataract asked“Do you intend to put a new lens in the eyeafter removing the old cloudy one?”

Since the 1930’s, Sir Harold Ridley had beenlooking for a ‘cure’ for aphakia but it was the‘Airplane Story’ from World War II that finally

provided the answer. A young fighter pilot, Flight Lieutenant Gordon ‘Mouse’ Cleaver, had hiseyes peppered with Perspex splinters from hiscanopy when his Hawker Hurricane was hit byenemy fire over France. It’s not clear exactlywhere Ridley saw Cleaver, probably at The RoyalLondon Ophthalmic Hospital (now Moorfields), but this patient provided him with the opportunityto observe the eye’s reaction to the material fromwhich IOLs would eventually be made.

Sir Harold’s encounter with the student gavehim the courage to proceed with his idea andon 29th November 1949, Sir Harold Ridleyimplanted the world’s first intraocular lens at St Thomas’ Hospital in London.

Forty years later in 1989, and once again in theUnited Kingdom, J. Stuart Cumming was on thebrink of developing a lens that he believed couldaccommodate just like the eye’s natural lens.

1980sIn 1989, a few of Stuart Cumming’s elderlypatients, who received plate haptic lenses thatwere 10.5mm long, reported that they could readeven though they were close to emmetropia.When sitting behind the phoropter and given theirmaximum distance correction, they could still readJ3 or better in dim light. He was also at that timeimplanting the three-piece SI18 lens (Allergan,Inc., Irvine, CA), and noticed at the slit lamp thatthe plate haptic lens optic appeared to vault muchfarther posteriorly in the capsular bag space than did the posterior-vaulted loop SI18 lens. The A-Constant of the plate haptic and SI18 lenseswere 119.0 and 117.2, respectively. The moreposteriorly vaulted lens design, however, would be expected to have the higher A-Constant2.

These findings, along with published data byThornton, Coleman & Busacca earlier that decade,suggested that forces within the eye tended tomove the plate haptic optic posteriorly, and theloop lens optic anteriorly. It seemed possible thatthese forces might also move the plate lens opticanteriorly with accommodation.

“Do you intend to put a new lens in the eye after removing the old cloudy one?1”

Dr Stuart Cumming (left), Mr Andy Corley (right), co-founders of EyeonicsEmmetropia The state of visionwhere an object atdistance is in sharpfocus with the eye’s lens in a neutral orrelaxed state or a fixed state created bythe implantation of a standard, non-accommodating IOL.

AphakiaThis medical term isused to describe theeye when it iswithout its crystalline lens either throughsurgical removal, congenital defect ordisease. Prior to the invention ofintraocular lenses, all cataract patientswere left in this state requiring them towear very high prescription glasses to see.

PRESBYOPIA 07

The first accommodatinglens was designed in1990 and implanted inthe eye of an 85 yearold lady in England on12th March 1991.

Alan Ritter, an ultrasound engineer who workedwith Cumming pre and post-operatively, measuredthe length of patients’ vitreous cavities. This smallstudy disclosed that the plate haptic lensesconsistently moved to the posterior part of thecapsular bag and shortened the vitreous 50% ofthe time, with the most anterior location only0.77mm in front of the original location of theposterior capsule. By contrast, the loop lensesshortened the vitreous cavity by only 20% of thetime, and lengthened it as much as 2.17mm. The spread of the plate haptic lens along the axis ofthe eye was 1.45mm, whereas that of the loop lenswas 3.15mm. Both of these 6 mm silicone opticlenses had the same refractive index and centrethicknesses of 1.3mm, and they were implanted inpatients in their 70s to replace crystalline lenses,approximately 5mm thick. Fibrosis, with ensuingshrinkage of the anterior capsule, caused posteriorvaulting of the optic of the plate haptic lens andpulled the posterior capsule tightly against theposterior surface of the optic.

As expected, subjects in the plate-lens grouphad superior UCVAs, because they had a muchshorter range of location along the axis of theeye compared with subjects in the loop-lensgroup. Additionally, the IOLs of the former groupfit tightly against the posterior capsule, thusstabilising the vitreous by maintaining it atclose to its pre-operative volume. This appearedto significantly reduce the incidence of retinaldetachment and posterior capsularopacification, which was less than 5% at 1 yearin the referenced studies.

He then measured the vitreous cavity lengthsand anterior chamber depths in the patientswho received plate lenses first, after instillingpilocarpine and, later, after instillingcyclopentolate. He found a 0.7mm averageanterior movement of the optic in 10 eyes.

These observations indicated to Cumming that afunctioning ciliary muscle was the onlymechanism that could account for his findingsand those published in the literature, and couldexplain why the optic could move in theseelderly patients’ eyes. By reducing the optic’sdiameter, the length of the plates could beincreased, thereby increasing the ability of the

optic to move. Thus, he hoped to design anaccommodating lens that would consistentlymove along the axis of the eye.

1990sThe first accommodating lens was designed in1990 and implanted in the eye of an 85 yearold lady at Bury General Hospital on 12th March1991. When examined on 25th July 1991, she demonstrated significant accommodationwith fogging. A-scans were than performed,first with her looking at distance, and then afterthe instillation of pilocarpine. Threeindependent scans showed an average increasein the vitreous cavity’s length of almost 2.5mmand shallowing of the anterior chamber byapproximately the same amount. These findings

conclusively showed that the ciliary muscle stillfunctioned in an elderly person and stronglysuggested that it would be possible to developan IOL that would consistently accommodate.In 1990, Stuart Cumming met Professor JochenKammann, MD, from Dortmund, Germany. Thetwo men worked in partnership over the next 9years, implanting seven lens designs, the first sixof which all demonstrated accommodation, boththrough patients’ ability to read at near throughtheir distance correction and by demonstratingoptic movement by means of A-scans withcycloplegia and, later, pilocarpine. The optic oftwo of the lens designs moved approximately1mm anteriorly after the administration of

pilocarpine. The designs were evaluatedsequentially. It took well over 12 months tochange the design to make new moulds,manufacture lenses of different powers, steriliseand package them, implant them, and observe

patients for possible complications. The patientswere carefully followed for a period of 3 months.

In 1998, Stuart Cumming joined forces with AndyCorley and formed Eyeonics Inc. The seventhCrystalens® design was first implanted in 1998.The plates were 10.5mm long, and the diameterfrom loop tip to loop tip was 11.5mm, with ahinge across the plate adjacent to the optic.

2000sThe Crystalens® received FDA approval inNovember 2003 with the AT45 model. This lensallowed the eye to focus on objects across abroad range of vision. It projected all availablelight received by the eye to a single focal pointand accommodated using the eye’s naturalfocusing mechanism.

In August 2005, the AT45SE came to the marketwith 360˚ square edge on the posterior side tohelp combat PCO and had availability in quarterdioptre steps in the most widely used powers toassist surgeons in targeting patient outcomesmore accurately.

The big change came with the FDA approval inNovember 2006 of the Crystalens® Five-O. This lens introduced an increased optic size from4.5mm to 5.0mm, a 12mm overall lengthavailable for larger eyes and a 17% greater hapticsurface area which provided greater stability.

The US market saw the launch of the currentCrystalens HD™ in June 2008, and in Europe inApril 2009. In continuing to model theCrystalens® after the natural human crystallinelens, the Crystalens HD™ is designed to mimicthe natural secondary mechanism of actionknown as accommodative arching. In theCrystalens HD™, the central portion of the lensis thicker than in the periphery, therebyincreasing the accommodative arching effect.

To date 150,000 Crystalens® lenses have beenimplanted world wide. To find out more, and tofind a surgeon near you, please visitwww.crystalens.com

PRESBYOPIA 08

Getting started with Crystalens HD™ Five recommended guidelines for success during your initial 10 eyes1. Pre-operative measurements• Use the IOL Master (Carl Zeiss Meditec, Jena, Germany) or manual keratometry to obtain keratometry (K) readings before applying any

eyedrops, applanation or corneal manipulation• For contact lens wearers, contact lenses must be removed for the appropriate amount of time to allow the cornea to return to a stable state • Use the IOL Master, or immersion ultra sonography to measure axial length• Make sure the axial lengths and K readings correlate with the patient’s oldest known refraction

2. Targeting• Utilise the Crystalens® nomogram for eyes 22mm or shorter• Dominant eye: Target slightly plus (between plano and +0.25). If the calculation does not predict plano, select the lens power that predicts

the first plus above plano• Non-dominant eye: Target slightly minus (between plano and -0.25). If the calculation does not predict plano, select the lens power that

predicts the first minus below plano

3. Lens power calculations• The SRK-T formula will be used for eyes with axial lengths measuring 22.01mm or longer, and the A-Constant for the Crystalens HD™

(HD500 and HD520) is 119.00• The Holladay II formula will be used for eyes with Axial Lengths measuring 22mm or shorter and in eyes with mena K flatter than 42.00D or

steeper then 47.00D, independent of axial length• Anterior chamber depth for the Crystalens HD™ is 5.55

4. Submit printouts• Submit both the Bausch & Lomb-Datalink pre-operative form and the A-scan or IOL Master printouts to your Crystalens® outcomes specialist

for verification of IOL powers - please indicate your lens choice and predicted outcome

5. Surgical and post-operative care, follow-up• Create a symmetrical capsulorhexis measuring 5.5 to 6mm• One day and 10 to 14 days post-op, perform testing listed on the Bausch & Lomb form and submit findings via Surgivision Datalink• Remember to measure intermediate acuity using the intermediate scale, distance corrected near visual acuity, and visual acuity in both eyes • Remember to verify refractive findings with a cycloplegic refraction when visual acuities and refraction do not correlate, or if near visual acuity is

not J3 or better

At age 72, I was frequently asked, “As a3.00 D hyperope, why haven’t you beenimplanted with the Crystalens®?” I finallydecided that I should put my eyes where mymouth was.

The next task was to carefully select thesurgeon. I have many friends with whom I hadbeen in surgery — all were excellent surgeonswho wanted to operate on me. However, I wasconcerned that I might become part of theiradvertising campaign since it is legal toadvertise as a physician in the United States. I had been in surgery several times with mygood friend Alan B. Aker, MD. Not only is hean excellent surgeon, but he also does notadvertise. I asked Dr. Aker if he would do mysurgery, and he kindly agreed.

We selected lens powers of 23.00 D for theright eye and 23.50 D for the left non-dominant eye so that the post-operative

refractions would be plano and -0.50 D,respectively. I reported for surgery on April 27,2005, for the first (left) eye. I was 72 years old.Dr. Aker implanted the 23.50 D Crystalens® AT45.

Dr. Aker implanted the second 23.00 DCrystalens® AT45 in my right eye on May 4,

The Crystalens® - through my own eyes

Dr Alan Aker (left) and Dr Stuart Cumming(right) – one day after Crystalens® implantationin Dr. Cumming’s second eye

2005. Both surgeries were withoutcomplications. Atropine 1% was instilled theday of surgery and 1 day post-operatively.

Immediately post-operatively, my pupil waswidely dilated, and I found it difficult to drive atnight because of the glare and halos.Fortunately, it appears that the effect of atropinein elderly patients significantly wears off in 3 to4 days. After this time, I was free from glare,and the pupil was down to about 3 to 4mm.

By day 4 post-operatively of the second eye, I was seeing well in each eye without glare atnight. My UCVA was 20/30 and J3 at 1 weekpost-op in each eye. At 2 weeks, my BCVAwas 20/20, and my UCVA in both eyes was20/25 and J2. I had a vertical diplopia thatwas relieved by tilting my head down, whichgradually improved over 4 weeks.

I am delighted with the results. My near visiongradually improved during the first 12 months.Now, most of the time I am without my 1.00D reading glasses, which I wear only when Isit down to read for a prolonged period. Thecomputer is also crystal clear without glasses.

I am finally functioning 90% of the timewithout glasses or contact lenses. My visionis as you would expect it to be if I were 35years old, and I can usually read the menuwithout glasses in a dimly lit restaurant. I have no loss of contrast and do not takemy reading glasses to restaurants. There isno glare or halos, and I have never seenshadows of the edge of the 4.5 mm, 0.9 mmcentrally thick optic, which is located deepin the eye, in the posterior part of thecapsular bag. At my age, the bag is onaverage 5 mm deep. My refraction onSeptember 28, 2005, at 5.5 months post-op,is listed in Table 1.

I play golf, and in myfoursomes there areusually eightCrystalens® eyeskeeping their eyes onthe ball and markingtheir cards withoutglasses. Like me, theyare all happy withtheir vision.

Crystalens HD™ now in quarterdioptre stepsBausch & Lomb (Surgical) are happy to announce that it has received approval from the Food and Drug Administration (FDA) to market the Crystalens HD™ in quarter dioptre steps. This announcement comes as the Crystalens HD™ celebrates its 1st anniversary sincereceiving the "Gold Standard" FDA approval, for proof of clinical effectiveness.

Dr. John Hovanesian, a principal investigator inthe FDA study and clinical instructor at the JulesStein Eye Institute, UCLA in California, said: “If Iwere a patient having cataract surgery, I wouldwant an IOL that projects 100% of available lightto a single point of focus in the eye, and alsoprovides a broad range of distance, intermediateand near vision. The Crystalens HD™ is the bestavailable lens to achieve that goal. There is noquestion that the Crystalens HD™ is my lens of

choice for presbyopia correction in patients withcataracts, and the addition of quarter dioptreswill only enhance my ability to target and givepatients the best possible outcomes with theCrystalens HD™.”

Quarter dioptres will be available for theCrystalens HD™ for models HD500 and HD520 inthe 18-22 range. Bausch & Lomb expects to makeavailable the dioptres in a wider range by theend of the year.

PRESBYOPIA 10

Sight over fortyDemographic Opportunity - we are rapidly approaching a worldwide population of 1.5 billionpresbyopes1. The presbyopic population is growing faster than the population as a whole.

Clearly, as an increasing number of ourpatients live longer and have more activelives, growth in this patient segment willremain robust for years ahead. Patientinterest in multi-focal contact lens correctionwill substantially increase in most of ourpractices as a result of consumer advertising,word of mouth, and trade advertising of newtechnology.

We need to be ready to help our patients reapthe benefits of new and emerging contact lenstechnologies for presbyopic correction. Ourmarket research shows only one in 10 of thevision corrected population age 50-64 wearcontact lenses; and of those, one-third ofmonovision wearers and one-third of regularcontact lens wearers would be willing to wearmulti-focal contact lenses2. When we advertiseour multi-focal contact lenses, your patientsrespond.

The ageing eye The anatomical changes which cause presbyopiaare well acknowledged. In childhood, thefocusing ability of the eye is provided by aflexible lens within the eye that is controlled bya series of surrounding muscles. When a personwants to see something up close, the overallfocusing power of the eye needs to increase.This is achieved by the flexing of these internaleye muscles which causes the shape of the lensto change to allow for ‘near’ vision.

The lens itself is very flexible at birth, whichmeans that it has a very wide range of focusingability. This is one of the reasons why childrenare able to sit very close to the televisionwithout discomfort, as well as colour withcrayons with their noses almost touching thepage. If a person wishes to view an object in

With age, the lens thickensand its increasing bulkmeans that it becomesinflexible, which in turndirectly impacts on theability to focus close up.

the distance, the muscles relax, the lens revertsto its original shape and the target comes intoview. All of these changes are madeinstantaneously and accurately.

With age, the lens thickens and its increasingbulk means that it becomes inflexible, which inturn directly impacts on the ability to focusclose up. People in their twenties and thirtiesare generally unaware of any changes, becausethe increasing rigidity of the lens only affectsobjects which are very close to – perhaps (10-20cm) away from the face. However, whenpeople reach their forties, the lens is able tochange its shape to a more modest degreewhich means items at arm’s length are clearlyvisible, but some tricky ‘near’ tasks such asreading small print in dim conditions orthreading a needle become difficult. You canoften identify a person experiencing presbyopiawhen dining in a restaurant if he or she isholding the menu at arm’s length!

At age fifty plus, there is essentially noflexibility left in the eye’s lens and for manypeople, near work is not possible without theassistance of some ‘refractive correction’ whichis usually in the form of spectacles or contactlenses. Whilst these changes happen toeveryone, the precise effects can differdepending on whether the person is short orlong-sighted. For example, people who arelong-sighted are often affected earlier in life.Those who are short-sighted struggle withdistance vision under normal circumstances,

but have an in-built advantage for ‘near’vision. They require less use of the eye’s lensand can often read close up for many moreyears than their friends who are neither longnor short-sighted.

AppearancesThere are many age-related conditions suchas memory loss that cause great concernfor people. Yet when we focus specificallyon the visual signs of ageing, concernsrelating to eyesight are at the forefront ofpeople’s minds. In fact, almost twice asmany people worry about dependence onglasses than going grey or developingwrinkles.

Impact of presbyopia on daily lifeLeisure research indicates that dailyactivities such as reading are negativelyimpacted by presbyopia3. Nearly 80% ofpeople with presbyopia struggle to readmedicine and food labels. Clearly, thepotential ramifications of someone takingan incorrect medicine or dosage could bevery serious.

Almost half (49%, Figure 1) of sufferershave difficulty writing cheques or payingbills and more than one in five have evengone so far as to sign a bill or credit cardslip without being able to read thecontents, putting themselves at risk fromerror or fraud. Nearly 60% of sufferersadmit they struggle with daily tasks, suchas using a mobile phone, which can provefrustrating. Meanwhile, 40% of sufferersfind it difficult to read their wrist watch.

It is concerning that patients are unawareof vision correction solutions available tohelp them to overcome these difficulties.

PRESBYOPIA 12

Products AvailableSpectaclesDevelopments in contact lensmanufacturing, design and materials meanthat there is a whole array of products forthe presbyopic patient. Meanwhile moderntitanium spectacle frames are so light that itis almost impossible to tell that they arebeing worn.

Pros• Modern titanium frames are very light to

wear and often visually appealing

• Recent technology now allows for moreattractive lenses even for strongerprescriptions

• Spectacles can help create a certain look,becoming a fashion accessory

Cons• Some find glasses uncomfortable to wear

• Can be restrictive in certain daily lifescenarios, for example while playing sport,when needing UV protection or whenapplying make up

Multi-Focal Contact LensesMulti-Focal and bifocal contact lenses workby producing a clear distance focus and aclear near focus on the retina. Fortunately,the brain is a brilliant vision processor andcan quickly adapt to the vision provided bythese types of lenses.

Pros• Peripheral vision is unaffected and is usually

enhanced due to the panoramic visionprovided by contact lenses when comparedwith the restriction of a spectacle frame.

• Ideal for patients who are wearing visioncorrection products for the first time, whoare not used to wearing glasses.

• Enables daily life activities such as playingsports, telling the time on a watch, using amobile phone or applying make up in themorning.

• The idea of being able to read withoutspectacles is ideal for social occasions.

Cons• The usual prescription suitability applies.

Astigmatism requires consideration withrespect to lens type. For patients whosedistance prescription requires moresophisticated contact lenses, soft multifocalcontact lenses are not as widely available.

• It may take some patients a few days toadapt to wearing the lenses.

Often, people experiencing presbyopia do notfully understand their progressively changingvision and worry that wearing spectacles willmake, or has made, their eyes worse. Whilstrefusing to wear vision correction does not slowdown or speed up the development ofpresbyopia, it is certainly inconvenient for thoseaffected, something that can be avoided whenthere are so many options for the correction of‘near’ vision problems.

People in the UK have their eyesight checkedmore regularly than anywhere else in Europe(Figure 2), with two out of three of thosesurveyed getting their eyes tested at least onceevery two years.

Those in their 40’s get on very well with Multi-Focal contact lenses, and if you startfitting them early, they can progress easily in to a higher add as they enter their 50’s. This will also keep these patients from droppingout, and endear them to you and your practice.

Patient OpportunityTwo recent studies point to the success that can be achieved with the Bausch & Lomb Multi-Focal contact lenses. Richdale found that 76% of her subjects preferred SofLens®

Multi-Focal lenses to monovision correction4.High contrast acuity was good (20/20 “atleast”) at both ‘distance’ and ‘near’ and stereo-acuity was far better with Multi-Focal lenses.Patients had a slight reduction in low contrastacuity with the Multi-Focal lenses at ‘near’(20/32 vs 20/28 with monovision). A more recent study also found stereo-acuitybetter with PureVision® Multi-Focal lenses5. In addition, the range of ‘near’ vision wasbetter for the patients wearing the Multi-Focallenses. While these researchers found somedifferences in visual acuity, ‘distance’ and ‘near’acuity was good, and contrast sensitivity wasnot significantly different.

The authors commented that the PureVision®

Multi-Focal lenses “can potentially provide abetter balance of real-world visual functionbecause of minimal binocular disruption.” The Bausch & Lomb multi-focal lenses in thesestudies shared the centre-near aspheric designthat also controls spherical aberration to expandthe range of clear vision.

Business OpportunityWhen fitting and treating presbyopes, a happypresbyopic multi-focal contact lens wearer is aloyal patient who is willing to refer otherpresbyopes for the opportunity to see well atdistance and near with contact lenses. Bausch &Lomb is committed to helping the eye carepractitioner provide the best vision solutions foryour patients throughout their lives.

Monovision Contact LensesMonovision is a system of contact lensfitting where one lens power is enhancedfor reading vision. That is, one eye iscorrected for distance vision and the otherfor near vision.

Pros• Peripheral vision is unaffected and is usually

enhanced due to the panoramic visionprovided by contact lenses when comparedwith the restriction of a spectacle frame.

• Monovision can be used with all types ofcontact lenses, including lenses that correctastigmatism, as it is simply theenhancement of the power of one of thelenses that achieves the visual results.

Cons• The eye works more or less alone with

monovision, meaning the wearer may haveto adjust the head position more often tosee. He or she may also lose some depthperception.

• As the eyes adjust to the new lens powers,a period of time may be necessary tobecome familiar with the lenses.

• Because correction is provided only forreading and long distance vision,intermediate vision (at approximately onemetre in distance) may not be as clear aswith multifocal contact lenses.

Often theatre staff find the move to a MICS™approach rather daunting.Mina Ward’s presentationon moving yourdepartment to MICS™showed how you canmake the move costneutral, and that in herexperience, barring aminimal change to

instrument sets, the transition has less of animpact than you might think.

Education and communication is key to anychange within a department and this is why we encourage both surgical and clinical staff toattend our MICS™ courses. As Mina points out“It’s not an individual that needs to change, you need to work as a team”.

The theatre staff that attended on the day foundit refreshing to have a portion of the daydedicated to MICS™ from their point of view.

Richard Packard concluded the day’s presentationsby giving a thorough description of both theCoaxial and Bimanual MICS™ techniques, payingcareful attention to the consideration of everyfacet of the surgery. This began with the choiceof incision size and the proper construction ofcorneal wounds, through to the matching ofappropriate instrumentation and fluidics, andfinally the cortical clean-up and implantation of a MICS™ lens.

The audience found it extremely beneficial tohear Richard’s tips for each stage of the cataract

Induced astigmatism from temporal wounds

Over 100 people have already attended theBausch & Lomb MICS™ courses this year andthese have proved a great success. Our MICS™Tutors, Richard Packard and Mina Ward, haverecently transitioned the Prince Charles EyeUnit in Windsor to MICS™ and gave advice,suggestions and solutions to issues that theunit was previously facing.

Please find below a brief overview of our Bausch& Lomb MICS™ Course held recently in Leeds togive you an insight into the day’s events.

Richard Packard started by talking about thehistory of MICS™ over the past forty years. From the first phaco-emulsification performedby Charlie Kelman in 1967 which gave us SICS(Small Incision Cataract Surgery), through to sub1mm MICS™ (Micro Incision Cataract Surgery)performed by Amar Agarwal today. MICS™ wasa term originally registered as a trade mark byJorge Alio, a surgeon from Alicante, Spain, forsurgery through sub 1.5mm incisions, but mostpeople now consider anything that is sub 2mmto mean MICS™.

There are two different approaches to usingMICS™, with both Coaxial MICS™ (CMICS) andBiaxial MICS™ (BMICS). There are advantagesand disadvantages with both options havingprotagonists and antagonists. However, CMICSseemed to be the audience’s preference withdelegate feedback containing such comments as ‘a change to CMICS is imminent [in mytheatre]’ and ‘CMICS does not require additionalclinical skills’.

Is surgically induced astigmatism dependent on incision size and site?A. Castillo UK, B. Redmill, B. Attrup

Purpose: To evaluate the results of refractive outcome with reference to induced astigmaticerror and post-operative astigmatism by comparing incision size and incision site.

Setting: Department of Ophthalmology, Lincoln County Hospital, Lincoln, UK.

Methods: In this 1365 case evaluation, patients had cataract surgery with either superior ortemporal clear corneal incisions and either sub 2mm incisions and a Bausch & Lomb Akreos®

MI60 implant or a 3mm incision with a Bausch & Lomb L161AOV implant. Measured outcomeswere astigmatic error induced as measured by vector analysis and post-operative astigmatism as measured from post-operative refraction. Data collected included pre-operative vision, pre-oprefraction, pre-op K readings, pre-op axial length, lens type implanted, lens power implanted,predicted refraction, A-Constant, incision size, incision site, post-op vision, post-op refraction,patient satisfaction and surgical complications.

Results: Data for 285 procedures using an Akreos® MI60 lens implant (Bausch & Lomb) wereanalysed. 219 cases used temporal clear corneal incisions and 66 cases used superior clearcorneal incisions. Data for 1080 procedures using a L161AOV lens with 690 temporal and 390superior incisions. 2 way ANOVA statistical analysis showed that significantly less astigmatismwas induced with the sub 2mm incisions as measured by vector analysis (%variation 0.48, p value 0.0101). It also showed that post-operative astigmatism was significantly less fortemporal incisions (%variation 0.39, p value 0.0215).

Conclusions: Micro incision sub 2mm cataract surgery significantly reduces the amount of inducedastigmatism as measured by vector analysis. Temporal clear corneal incisions lead to significantlyless post operative astigmatism than superior clear corneal incisions.

Refractive outcomes following micro-incision cataract surgery lens implantation

S. Prasad, U. Saeed, S. Awotesu, B.V. Kumar

Purpose: To find out refractive outcomes after bimanual micro incision cataract surgery and lensimplantation.

Setting: Department of Ophthalmology, Arrowe Park Hospital, Wirral University Hospital NHStrust, Wirral, Cheshire CH49 5PE

Methods: Retrospective collection of data of patients undergoing bimanual MICS™ was donefrom Electronic patient records (Medisoft). Pre-operative biometery and keratometry wereperformed with IOL master using an adjusted A-Constant 118.5. Surgery was carried out withtwo superior clear corneal 1.6mm incisions at 10 o'clock and 2 o'clock positions. Bimanualcataract surgery was carried out with a sleeveless phaco-emulsifier hand-piece and an irrigatingchopper. Irrigation aspiration was carried out by a bimanual irrigation aspiration system. Anintraocular lens (Bausch & Lomb Akreos® MI60) was inserted in the capsular bag after enlargingthe wound to 1.8mm and using wound assisted injection technique. The post-operative refractionand complications were noted.

Results: Data regarding 49 eyes of patients who underwent cataract surgery was collected andanalysed. All patients underwent bimanual MICS™ with no intra-operative complications noted.Simultaneous refractive procedures like arcuate keratotomy or limbal relaxing incision were notperformed. The average deviation from predicted refraction based on SRK-T readings were+0.162 dioptres in spherical equivalents (standard deviation 0.62). Minimum deviation of 0 andmaximum deviation of +1.88 dioptres was seen. Average change in astigmatism was calculatedto be -0.08 dioptres. (Standard deviation was 0.69 with a calculated median of 0). Maximumchange in astigmatism induced ranged from +1.75 dioptres to -1.5 dioptres.

Conclusions: Bimanual micro-incision cataract surgery (sub 2mm) can be successfully carried out with small changes in incision induced astigmatism. The A-Constant may be personalised fora particular surgeon and IOL, if the biometery parameters remain consistent. The A-Constant forthis particular lens was adjusted with good refractive results.

Steve Martin, Director of Influence at Work (UK)

ACADEMY OF VISION CARE™ 16

The Science of ComplianceIn the third of our series of articles on ‘the role of influential communication’ Steve Martin and Nick Pope continue their look at ‘the role of persuasion’ and considerthe influence of others on the decisions we make.

For over sixty years persuasion researchershave studied the influence process and foundthat anyone can significantly increase thelikelihood that others will be persuaded bytheir requests, messages and advice byemploying one or more of the six universalprinciples of influence.

These principles are:

Social proof - people behave in a similarway to others who are like them

Reciprocity - obligates people to do forothers what they have done for them

Consistency - causes people to act in linewith previous commitments even if demandsescalate

Authority - people defer to those withexpertise and credibility to guide theirdecisions

Liking – people are influenced more bythose whom they like, and who like them

Scarcity - opportunities appear morevaluable when they appear less available

Although there is little doubt that other people’sbehaviours are a powerful source of socialinfluence, in studies when people are askedwhether other people’s behaviour influences theirown, they will often insist that it does not, butexperimental social psychologists know better.

One of the simplest demonstrations of thepersuasiveness of others’ behaviour over ourown, was a classic study that was originallyconducted almost 60 years ago. PsychologistStanley Milgram simply asked one of his studentsto stand on a busy street corner and look up inthe air. While the student was staring into space,Milgram stood on the other side of the road andcounted the number of passers-by who stoppedand looked into the air too. The result? Very fewuntil Milgram made one small change.

Instead of asking one student to stand on thebusy street corner and stare into the air hearranged for a group of five students to do so.

Now some 400% more passers-by stopped andstared into space for no other reason than‘everyone else seemed to be doing it’.

So the behaviour of an initial group can causemany others to be persuaded to behave in thesame way – especially when information islacking or people are uncertain. Even thoughmost of us would prefer not to admit it, this herd-like following of others is a veryefficient shortcut to a (generally) good decision. For example, imagine you are on holiday andlooking for a good place to eat one evening.One way of choosing a restaurant is to look inyour guidebook for a recommendation. But what if nothing in your guidebook appealsto you? Or what if you don’t have a guidebook?What would you do?

Maybe you might find yourself being drawntowards the busiest restaurant. You think “ifeveryone else is eating there then it must bethe best place for me to eat too”. Your decisionhas been influenced by the behaviour of others– a phenomenon called social proof.

Unfortunately for Eye Care Professionals, when anindividual is trying to decide which optician theyshould make an appointment with, they are

unlikely to witness a lengthy queue outside onespecific practice that provides them with socialproof information that this is the place to go.

So does this mean that because other people’sbehaviours are unlikely to be witnessed first-handin the world of optometry and ophthalmology that social proof cannot be employed by Eye CareProfessionals? We think not.

Results from numerous studies confirm that we don’t necessarily need to see peoplebehaving in a certain way to follow theirbehaviour. We just need to know of informationthat they have behaved in a particular way. In one study persuasion researcher RobertCialdini was able to increase by 26% thenumber of hotel guests who were willing toreuse their towels by simply informing guests,

via a commonly used card in hotel bathrooms,that the majority of other guests who had been staying in the hotel had also reused their towels. An entirely honest and effectivestrategy that was costless to implement.Therefore, informing patients of your mostpopular lenses, solutions and spectacles can be a very productive and persuasive thing to do assuming that those choices are potentiallyright for them too.

Research into the social proof phenomenonshows that when people are anxious oruncertain they are especially influenced bysocial proof. As a result, an eye carepractitioner who gently points out that “otherpatients like them often feel nervous at thestart of the exam but quickly find they are ableto relax” is providing some very important andpotentially persuasive words of comfort to anuncertain or anxious patient.

The social proof approach should also beeffective when it comes to helping patientsmake choices, say between lenses and

in such cases it would be most persuasive topoint out the number of other youngprofessionals you have on your patient listwho have chosen these lenses. The evidenceshows that the ‘people like me’ approachdoesn’t just hold for age and profession butcan hold for other characteristics such as theirgender or sports interests. For this reasonalone it can be very useful to pass oninformation about individual patients you haveexamined to colleagues who are responsiblefor talking about the products and servicesyou offer. By doing this you will ensure thatthey can select the most relevant social proofinformation to provide to patients.

Additionally, evidence from social proofstudies show that the more tailored the socialproof information provided is for ‘people likeme’, the more persuasive it becomes. For example, imagine you believe that ayoung professional patient of yours is mostsuited to daily disposable contact lenses, and

“Working in the Lincoln area I am very lucky tohave the support of our local optometrists whohave committed to providing the local cataractservice with feedback on patients’ refractiveresults, following phacoemulsification.

Using data the optometrists have provided, we have been able to refine some of ourpractices in theatre, and one of the mostimportant of these, I feel, is the optimisationof the A-Constant used for intraocular lenses.Whilst lens manufacturers do their best toprovide us with an accurate A-Constant, it is often based on laboratory studies and it is imperative that each of us adjust our A-Constant to perfect the refractive outcomes.

Do you have an interesting topical news

story to tell, or a worthy article that you

would like to share with the rest of the

using the address on the back cover.

Your opinion is greatly valued…

In a recent study in Lincoln County Hospital, we found that by using the refractive outcomedata from patients receiving the Bausch & LombMI60 lens, we could adjust the manufacturers’A-Constant (from 118.4 to 119.0 in thisinstance) to leave 91.4% of patients within 1 dioptre of predicted refractive outcome.Resulting in an 8.3% increase on using themanufacturers’ A-Constant.

I would highly recommend that every surgeoncarries out a similar review to ensure that theyare giving their patients the very best result.”

Response by ‘Visions’Thank you Andrew for your letter and for yourcomments on A-Constant. We agree thatoptimisation of the A-Constant of a lens is veryimportant. Bausch & Lomb, as manufacturers,provide an A-Constant based on our laboratoryexperiences and insight into the design and lensmaterial as a basis for your calculations.However, we cannot take into account everyfactor of a surgeon’s individual approach andoften technique, method of biometry and choiceof lens calculation formula will have an effect onthe best A-Constant for the lens.

“I was recently offered the chance by B&L tobe the first in the UK to trial a new design of your single use irrigation handpiece. This new variation has an entirely silicone tip surrounding a metal aspiration tube.

I was keen to see whether this design wouldoffer significant improvements over thecurrent metal tipped designs whilst curious asto whether a silicon formed tip would deformunder vacuum.

I performed ten surgeries with the handpiecesand was very impressed. The tip is extremelysafe to use in capsule polishing and corticalclean-up as at no time is there any metal orsharp port edges in contact with the capsularbag. It is also robust enough not to deformunder vacuum or during port occlusion and beused for IOL manipulation. I also let two ofour junior staff try the handpieces and theyfelt very reassured by the safety of thesilicone design, especially when an occasionalsnagging of the capsule occurred.

I think this technology offers significantbenefits in safety to all surgeons, bothtrainees and consultants, and haverecommended we move to it immediately inmy theatre.

Thank you for allowing myself and the team atSt Helier Hospital to be the first to have a go.”

Did you know?

The largest eyeball ever to be studied on the planet belonged to a Colossal Squid

(Mesonychoteuthis hamiltoni) which was recovered in New Zealand. At 27 centimetres

(11 inches) across the eye dwarfs our human equivalent many times over. The squid's

crystalline lens was 5 centimetres across and split into two parts; a common feature

in cephalopods.

Speculating on the size to which these elusive creatures grow, scientists believe that

their eyes may be anything up to 45 centimetres (18 inches) wide, which would make

them roughly the same size as a watermelon, with a lens equivalent to an orange!
