ZEISS AT LISA IOLs are based on the unique LISA concept, which comprises the following features:
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.
Independence from pupil size due to high-performance diffractive-refractive micro-structure covering the complete 6.0 mm optical diameter.
SMP technology provides a lens surface with no sharp angles for ideal optical imaging quality with reduced light scattering.
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
