AT LISA Trifocal 839 preloaded

 

Patient Satisfaction

Freedom from vision restrictions and corrective glasses is the wish of most cataract, presbyopia or astigmatism patients.

With the exceptional performance of ZEISS AT LISA tri family an active life without limitations becomes reality, satisfying the needs of even the most demanding patients.

With ZEISS AT LISA tri family, patients experience enhanced contrast sensitivity resulting in a better night vision. Moreover, they report a low level of dysphotopsia and, due to quick neural adaptation, they can enjoy the benefits of trifocal IOLs shortly after implantation.

In the end, the majority of patients do not need glasses in their daily lives. Spectacle independence after the implantation of an AT LISA tri lens reaches nearly 100 %.

The referral rate for AT LISA tri IOLs from ZEISS is also very high: 97% of the patient treated with these lenses would recommend them to their families and friends; as shown in a recent Mexican study.

 

Outstanding intermediate vision

ZEISS AT LISA tri family offers the outstanding intermediate visual performance that can only be achieved with a real trifocal IOL design.

The superior intermediate vision with ZEISS AT LISA tri family becomes evident when compared to an apodized bifocal IOL or a trifocal IOL with convolution design.

Due to the intermediate addition of +1.66, ZEISS AT LISA tri family significantly improves visual acuity at the intermediate distance, enabling your patients to feel more comfortable performing daily activities in this vision range.

 

 

Excellent optical efficiency

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

Designed to meet the highest expectations, ZEISS trifocal platform offers numerous advantages, such as:

Improved visual acuity

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

Smooth transition

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.

Increased overall light transmittance

The refractive-diffractive profile designed to enhance intermediate vision over the central optic of 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 AT LISA tri lenses is based on the proven long-term results of the LISA platform and ensures consistent optical performance regardless of the lighting conditions.

Improved night vision

The optic design of 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 with no further obstacles.

Excellent image quality

Based on the proven Smooth Micro Phase technology, the lens surface of AT LISA tri does not have any sharp angles, resulting in ideal optical image quality with reduced light scattering.

 

 

ZEISS AT LISA tri family, the next generation trifocal MICS IOL platform is the result of years of experience in the development of optical designs. It is specially designed to match your highest expectations for a predictable and effective multifocal IOL to suit a wide range of patients.

AT LISA tri geometry

 

The optical zone of ZEISS AT LISA tri 839MP and ZEISS AT LISA tri toric 939MP provides a near addition of +3.33 D for a comfortable reading distance and a intermediate addition of +1.66 D to perform most daily activities.
