Light rays pass through the clear part at the front (the cornea) and pass through the

lens, which focuses them onto the "screen" at the back of the eye called the retina. There, billions

of photoreceptors (light-sensitive nerve cells) convert the image into electrical impulses that are

transmitted to the brain.

But not everybody's eyes are perfect. When the cornea, lens or eye is an abnormal shape, light

cannot focus accurately on the retina and the image is blurred. The most common sight

defects are as follows:

Myopia

Hyperopia

You and your eyes

Astigmatism

(Nearsightedness): if you are myopic, light rays come to a focus before they strike your retina.You are able to seeclose objects clearly but everything in the distance becomes blurred.

(Farsightedness): hyperopic people can see distant objects clearly but have difficulty focusing on closer ones,as the rays come to a focus behind the retina.

Both near and distant objects appear blurred. It occurs when the light rays travel in two different directions insidethe eye rather than being focused to one point.

In the last decade, laser eye surgery has become a routine method of correcting defects like those above.The principleis simple: using microscopic points of fine laser light, the cornea is re-shaped, allowing light rays to focus accuratelyon the retina.

Excimer lasers have become ever more accurate over the years and the most recent development - WavefrontGuided Custom LASIK - uses systems more precise and less invasive than any developed so far.

Phiroze Dastoor is currently the only clinic in Mumbai to offer Wavefront Guided LASIK with Customize software using a Tscherning aberrometer, as well as conventional LASIK, allowing us to select exactly the form of treatment that

Conventional LASIK corrects only prescription (sphere and cylinder) and a single central reading of corneal curvature map.For those people who have lower prescriptions, typically those up to -3.0 to +2.0 dioptres without astigmatism or

irregular corneal curvature, conventional LASIK may suffice.

Conventional LASIK

The laser itself

Wavefront Guided Custom LASIK Customised LASIK has a higher potential for perfect vision and lower potential for visual compromise. Patients

with more complex prescriptions, unusual corneal shapes or who want the best visual outcome will benefitfrom Custom LASIK.Every patients eye differs in corneal shape, corneal thickness and pupil size.Wavefront technology analyses

the entire visual system from the corneal surface through the crystalline lens of the eye, all the way back tothe retina.A device called a Tscherning Wavefront Analyser projects a fine grid of 168 light beams onto the retina

and captures its image using a high-resolution camera. The image is then compared with one from a normal eye andthe information is used to create an ideal vision correction profile which removes any distortion from the opticalpath in order to bring an object into perfect focus. Due to the flexibility of numerous possible treatment patterns thelaser beam will treat each point in a larger surface of the cornea precisely according to a unique treatment plan.

The benefits of Custom LASIK

Greater opportunity of achieving 20/20 visionGreater opportunity of achieving better than 20/20 visionReduced opportunity for night vision and glare problems

Where older lasers produce a broad, square-shaped beam, ours has a more rounded,sharply-focused profile measuring less than 1mm across.

This allows us to remove the minutest amounts of corneal tissue with greater accuracy,resulting in a more stable cornea - essential to sharper vision.

In addition to this extraordinary technology you need, of course, extraordinarily skilled people to use it, and vPhiroze Dastoor has just the team. We also have a dedicated team of support staff,, who assist our surgical team and lookafter our patients throughout every stage of the procedure.

Not every eye is suitable for laser treatment. It might surprise you to know that we turn down about half thepeople who come to us.Phiroze Dastoor consultants will examine your eyes using equipment as unique as the Wavefront technology itself.To assist them, please do not wear soft contact lenses for a week and rigid ones for two weeks beforehand. Lensesdistort the cornea and might influence the outcome of the treatment.

If you have any old prescriptions for lenses or glasses (or details of any eye treatment you have had in the past),please bring them along: if we can see how your eyes have altered over time, we can best determine h

that you make arrangements for someone else to drive you back home.

ow to treat them.Dilatation of the pupils may temporarily blur the vision of some people for a few hours. Therefore, we advise

On the day of the procedure please arrange to have someone with you. Please do not wear perfumes,make-up, gels or sprays either, as fine vapours can interfere with the path of the laser beam.

If you have any anxieties whatsoever about your treatment, our support staff will be happy to assist you.Our aim is to make you feel as comfortable and relaxed as possible.

Once the laser has been calibrated, your eyelids are held open and your eyes anaesthetised with drops.Then, using a precision device called a microkeratome, the surgeon creates a micro-thin flap on the surface

of the cornea.The flap is gently lifted to one side, the bed of the cornea (the stroma) is exposed and the laser reshapes this surface to re-focus the eye.After 30-60 seconds, the flap is repositioned.

The flap holds itself naturally in place, but we do recommend you wear protective glasses or the shield we provide you with to prevent you from rubbing your eyes for a few days.

After resting for a short while in our waiting area, we will examine your eyes again before you leave.

Before you go home, our staff will give you personalised after-care instructions and eye drops.Your vision may beblurred for a few hours so please ensure that there is somebody else to take you home.

After the procedure for a short while you will experience watering of the eyes and feel as if there is something "stuckin your eye". This is quite natural, but on no account must you rub them.

After your surgery, we will see you several times again over the next year, and examine your eyes using the same equipment as before.This way, we can properly monitor the success of your treatment.

Most people can return to work within 24 hours after the procedure. However, there are a few other activities thatneed to be carried out with due care:

Showering - The next day with your eyes closed

Driving - When you are comfortable with your new vision, and if it meets driving standards

Heavy exercise - After one to two weeks depending on how comfortable your eyes feel

Swimming - After two weeks with goggles, or six weeks without them

Eye make-up - Mascara after four weeks, other make-up after two days

Very, very occasionally some eyes do not respond fully to laser treatment,and we may recommend that you go through the procedure again.This time, though,

the treatment is simpler, as it just involves lifting the flap and re-applying the laser.

How successful is laser vision correction at Phiroze Dastoor?

Our goal and our commitment to you is to get you to a level of 6/12 (20/40) or better, enough to function withoutglasses, to watch TV, play sport and take up occupations where good vision is essential. In fact, after treatment over95% of people can drive without glasses. Our consultants will discuss with you at the time of your consultation whatcan be achieved in your individual case.

Does it hurt?

No. LASIK is virtually painless.You may experience some mild to moderate discomfort and watering of the eyes for afew hours after treatment.This varies from person to person and has been likened to the sensation of having worncontact lenses too long.

Do the results last?

The effects of LASIK are permanent and they do not wear off. But it is important to realise that a person's eye canstill change internally.That is why many surgeons recommend having the procedure done after the major eyechanges have occurred in one's life.Your surgeon can review the changes you have had and help you make a decisionwhether or not LASIK is appropriate for you.

What can you do after the procedure?

Repeat procedure

What happens when I get older?

Natural changes occur in every eye.As we reach our mid 40s, the fine focusing mechanism of the lens within oureyes does not function as well as when we were younger. Therefore, it is most likely that you will require glasses forreading fine print when you reach your mid 40s. It is because this age-related change affects the lens in our eye andnot the cornea that LASIK cannot treat this change.

If I get LASIK done and my vision changes later in life, can it be redone?

In most cases, an enhancement may be a solution to vision changes later in life.Your eye care specialist will examineyour eyes and determine whether an enhancement can be performed.

What are the long-term side effects?

Laser eye surgery has been performed for more than 10 years and no complications have been documented thathave not been encountered in the first year of follow-up. Minor complications such as haziness, delayed healingand night time glare have been reported although these are very few and far between, and in almost all cases, canbe treated.

Is the procedure covered by health insurance?

Most health insurance companies do not cover LASIK.

How long before I can see well?

Visual rehabilitation after LASIK is rapid. Most people achieve good vision the day after surgery and find that theireyes feel fairly normal 24 hours later. However, your sight may improve even further, and the very best vision can stilltake two to three weeks.
