Improved night vision

True Living Vision

for improved night vision

Excellent optical efficiency – day and night

with AT LISA tri 839MP and AT LISA tri toric 939MP

The efficient optical design of the ZEISS AT LISA tri family provides high-resolution images with outstanding contrast sensitivity at all distances and under all light conditions.


Enhanced intermediate visual acuity

Enhanced intermediate visual acuity, especially after binocular implantation 1

Improved visual acuity

The ZEISS AT LISA tri IOLs improve visual acuity over the whole vision range, especially after binocular implantation.

AT LISA tri defocus curve

Defocus: Visual acuity over a range from 25 cm to ∞ 1

Smooth transition

The ZEISS AT LISA tri family enables a smooth transition between near, intermediate and far. Your patients will be able to switch back and forth between objects at different distances without the need to put on corrective glasses.


Overall light transmittance update

The refractive-diffractive profile designed to enhance intermediate vision over the central optic of the AT LISA tri increases the overall efficiency of light transmittance to an average rate of 85.7 %.

Asymmetrical light distribution

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.



Pupil independence

The maximized, pupil-independent design of the AT LISA tri is based on the proven long-term results of the AT LISA family and ensures consistent optical
performance regardless of the lighting conditions.


Improved night vision

The optic design of the AT LISA tri family with trifocal center and bifocal periphery ensures optimized night vision. After implantation of a ZEISS AT LISA tri lens nocturnal car trips or reading in a dim light can be performed without obstacles.


Excellent image quality

Utilizing the proven Smooth Micro Phase technology based on our proven LISA concept for the lens surface, the AT LISA tri optic does not have any sharp angles, resulting in ideal optical image quality with reduced light scattering.
