ZEISS AT LISA 809M

Offering your patients superior near and distance vision.

The AT LISA® 809M from ZEISS represents advanced multifocal technology, enabling patients to see clearly without glasses at near and far distances.
The platform offers an optimized optic design for an excellent visual outcome and a high degree of spectacle independence, including reading distance.
The ZEISS AT LISA 809M is an ideal solution for patients with particular near-vision requirements (e.g. avid readers).

Unique LISA concept

Outstanding visual acuity

Good contrast sensitivity

Unique LISA concept

For superior visual performance and higher patient satisfaction.

ZEISS AT LISA IOLs are based on the unique LISA concept, which comprises the following features:

L
Light is distributed asymmetrically
between the different focus points to ensure excellent vision at all distances. For AT LISA this translates into 65% of light being allocated to the far and 35% to the near focal point.

I
Independence from pupil size due to high-performance diffractive-refractive micro-structure covering the complete 6.0 mm optical diameter.  

S
SMP technology
provides a lens surface with no sharp angles for ideal optical imaging quality with reduced light scattering.

A
Aberration correcting optimized aspheric optic for better contrast sensitivity, depth of field and sharper vision.

The LISA concept greatly improves the visual performance of the lens, and thus allows surgeons to achieve high patient satisfaction. When asked “Are you satisfied?” and “Would you recommend the ZEISS AT LISA?” 100% of patients said “Yes!”.1

Outstanding visual acuity

At near and far distances

The AT LISA 809M delivers the familiar ZEISS superior optical performance and great visual quality for far distance. And with its additional focal point for near distance, ZEISS AT LISA 809M allows patients to achieve excellent near vision, meaning that reading small print and performing delicate work such as sewing becomes possible without any visual aids.

As a result, more than 90% of patients do not need corrective glasses for near and far distances.1,3,4

Good contrast sensitivity

Day and night

Due to the asymmetrical light distribution between far (65%) and near (35%) focal points, the light yield of the ZEISS AT LISA amounts to 80%, improving overall contrast sensitivity.

Compared to multifocal lenses with symmetrical light distribution, AT LISA IOLs provide a higher contrast sensitivity level – which lies within the normal range of healthy phakic patients, under photopic and mesopic conditions.

ZEISS Viscoject Injector

Eligible for MICS

For safe and convenient surgery

ZEISS AT LISA 809M represents the first generation of high-performance aspheric multifocal IOLs for 1.8 mm Micro Incision Cataract Surgery. This offers multiple benefits:

  • Minimizes the surgically induced astigmatism
  • Promotes rapid wound healing and accelerated postoperative regeneration
  • Decreases the risk of endothelial cell loss
  • Reduces the risk of inflammation

Moreover, the ZEISS AT LISA platform offers good stability and centration in the capsular bag.
