Carl Zeiss Introduces the First Trifocal Preloaded True-MICS IOL for Enhanced Intermediate Vision

WELWYN GARDEN CITY, England, April 18, 2012/PRNewswire/ --

    The trifocal intraocular lens (IOL) AT LISA(R) tri 839MP is the next generation of
multifocal IOLs from the medical technology manufacturer Carl Zeiss Meditec
[http://www.meditec.zeiss.com/lisa-tri ]. AT LISA tri supports ophthalmologists and
ophthalmic surgeons in meeting the demands of cataract and presbyopic patients who lead an
active life and expect surgery to provide them with a quality of vision which is similar
to what they were used to before the aging process of their eyes started. With AT LISA tri
[http://www.meditec.zeiss.com/lisa-tri ] patients can switch almost naturally between
near, intermediate and far distances without being troubled by corrective glasses. "Simply
put, there is no other IOL on the market that is as close to the natural accommodating
process as the AT LISA tri," says Dr. Wolfram Wehner, ophthalmologist in Nuremberg,
Germany.

    "We would like to assist our customers in optimally addressing the challenges of
surgical cataract and presbyopia correction," says Dr. Ludwin Monz, President and CEO of
Carl Zeiss Meditec AG [http://www.meditec.zeiss.com/lisa-tri ]. "With the AT LISA tri
trifocal IOL this means that patients are provided with the most natural post-operative
vision possible without being reliant on eyeglasses."

    Functional vision in all light conditions and lower visual disturbance

    Based on the established AT LISA platform, the AT LISA tri
[http://www.meditec.zeiss.com/lisa-tri ] is designed to produce more satisfying and
predictable visual outcomes to active patients and maximized pupil independency. The IOL
features a unique asymmetrical light distribution between the three different foci - 50
percent far, 20 percent intermediate, 30 percent near. Additionally the light energy
transmittance is increased for a maintained contrast sensitivity rate and lower visual
disturbance. "My patients report significantly less halos and glare with the AT LISA tri,
even when directly questioned about these phenomena," reports Dr. Elisabeth
Frieling-Reuss, ophthalmologist in Munich, Germany, about her experiences.

    AT LISA [http://www.meditec.zeiss.com/lisa-tri ] tri can provide enhanced intermediate
vision performance with its addition of +1.66 diopters compared to apodized bifocal or
convoluted trifocal IOLs, even under poor light conditions.

    Simple and safe implantation

    AT LISA tri [http://www.meditec.zeiss.com/lisa-tri ] is suitable for microincision
cataract surgery (MICS) to avoid intraoperative induced astigmatism and reduces higher
order aberrations. The preloaded AT LISA tri 839MP combined with the innovative BLUEMIXS
180 injector allows easy and safe implantation through an incision of 1.8 millimeters.

    To maintain lasting visual quality and prevent posterior capsular opacification (PCO),
AT LISA tri [http://www.meditec.zeiss.com/lisa-tri ] features an anti-PCO posterior
profile. This reinforces the effect of the square edges for double prevention of PCO
formation.

    With the addition of AT LISA tri [http://www.meditec.zeiss.com/lisa-tri ] to the ZEISS
MICS Platform, Carl Zeiss Meditec [http://www.meditec.zeiss.com/lisa-tri ] continues to
provide an even more complete and innovative range of products for micro incision cataract
surgery.
