Enjoy life in all dimensions

Today you are often confronted with patients who expect surgery to provide them with

a quality of vision which equals what they enjoyed before the aging process of their

eyes started. They want to lead an active life without being troubled by eyeglasses.

This is exactly where the new trifocal AT LISA tri 839MP comes into play.

4

3rd generation of ZEISS multifocal IOLs

AT LISA tri 839MP is the new member of the AT LISA family of IOLs.

It is based on the well-known, high performance AT LISA platform

with superior intermediate vision.

Far better intermediate vision performance

AT LISA tri 839MP displays a far better intermediate visual performance

compared with the performance of an apodized bifocal IOL or a trifocal with

convolution design even under poor light conditions.

The AT LISA tri maintains its full

resolution efficiency and contrast

transfer independent form the

illumination dependent pupil size.

The visibility of the small bars in the

central portion of the 1951 USAF

resolution test chart demonstrates

the ability of the AT LISA tri of high

resolution intermediary imaging

without compromising image sharpness

and contrast.

Far better intermediate vision performance

“AT LISA tri offers far better intermediate vision

performance to my patients, even in low light

conditions, without compromising performance

in near and far vision.” 

Dominique Piétrini, MD (Paris, France)

“The vision during computer work is excellent!” 

Jens Uhl, MD (Heilbronn, Germany)

8

Outstanding intermediate visual acuity

AT LISA tri 839MP significantly improves intermediate visual acuity enabling patients to feel more comfortable performing activities requiring vision at an intermediate distance.

Cutting edge trifocal optic

“With all the optical benefits from the complete redesign

of this lens it seems to me that AT LISA tri is really the

next generation of multifocal IOL that results in better

light transmission, optimised night vision performance

and trifocality giving excellent intermediate as well as

close vision ...” 

Patrick Versace, MD (Sydney, Australia)

“With the AT LISA tri, I can finally introduce my

patients to a real multifocal world without

sacrificing their contrast sensitivity and without

increasing their dysphotopsias.”

Joaquín Fernández, MD (Almeria, Spain)

10

Cutting edge trifocal optic

The optical zone of the AT LISA tri 839MP provides

• a near addition of +3.33 D for a comfortable

reading distance

• an intermediate addition of +1.66 D

It significantly improves intermediate vision

without compromising near or far vision.

AT LISA tri design is optimized for reduced potential

visual disturbances and improved night vision.

Unrivaled global light energy transmittance

AT LISA tri increases the overall efficiency of

light transmittance to an average rate of 85.7 %.

AT LISA tri optic does not have any sharp angles,

resulting in ideal optical image quality with

reduced light scattering.

Asymmetrical light distribution re-invented

With a unique asymmetrical light

distribution of 50 %, 20 % and 30 %

between far, intermediate and near

foci, AT LISA tri is able to provide

more satisfying and predictable

visual outcomes for younger

patients with active pupils.

You can expect an unsurpassed

rate of eyeglass independence

for the majority of your patients.

For a new vision of life – by day and night

“My patients report significantly less halos and glare with the AT LISA tri, even when directly questioned about these phenomena.”

Elisabeth Frieling-Reuss, MD (Munich, Germany)

“With the AT LISA tri 839MP IOL, excellent far and intermediate vision is combined with perfectnear vision quality.”

Jean-François Montin, MD (Paris, France)

“After 5 years implanting the AT LISA 809M, in over 6,000 eyes, I use the new AT LISA tri. AT LISA tri improves my results and provides increased patient satisfaction (magnified near vision, good distance vision and improved intermediate vision) and quality of vision.”

Fernando Llovet, MD (Valencia, Spain)

15

High resolution for all distances

AT LISA tri 839MP produces images with high resolution for all distances under all

light conditions. Your patients will be able to switch back and forth between targets

at different distances without the need to put on corrective glasses.

What patients say

Ensuring a high level of patient satisfaction

is the ultimate goal. To evaluate the

degree of satisfaction patients answered a

standardized questionnaire after implantation

of an AT LISA tri 839MP.

100 % of the patients judged their post-

operative visual acuity to be good,

very good or outstanding.

AT LISA tri is your reliable option for high

patient satisfaction.

Make it easy with the preloaded AT LISA tri

The innovative BLUEMIXS 180 injector combined

with the preloaded AT LISA tri 839MP allows easy

and safe implantation whatever your surgical

technique and your incision size.

18

Make it safer with the MICS AT LISA tri

Based on the well-known 4-haptic design of the ZEISS MICS IOLs, AT LISA tri

provides highly reliable stability as well as ease of implantation through 1.8 mm.

19

Make it last with the AT LISA tri anti-PCO profile

The design of the new AT LISA tri includes a ZEISS anti-PCO posterior profile.

This reinforces the effect of the square edges for double prevention of PCO

formation in order to maintain good quality of vision for as long as possible.

20

Attract new patients

Satisfied patients are the best multipliers for multifocal

IOL patient recruitment.

“Since my operation I do not wear glasses at all and

I have very good vision at all distances. I do not wear

glasses to read or even to work on the computer. I am

fully satisfied with the results and I would definitely do

it again without any doubt. I would recommend this

surgery to friends.”

21

Attract new patients

AT LISA tri provides you with the confidence of using the most advanced presbyopia

correcting IOL technology, offering state-of-the-art visual outcomes to an extended

group of patients. AT LISA tri is your reliable tool to extend your multifocal IOL patient

base in total confidence.

“The intermediate vision improvement

allowed by the AT LISA tri 839MP IOL

is a major benefit for prelex patients

and patients who want purely comfort-

oriented refractive surgery.”

Jean-François Montin, MD (Paris, France)
