For greater precision and outcomes in toric cataract surgery

Depending on the patients’ clinical condition and preferences, ZEISS offers a wide range of toric IOLs; from monofocal toric to EDoF toric to trifocal toric lenses. ZEISS toric IOLs are available in up to +12 diopter in cylinder and in 0.5 diopter steps , providing up to 2,000 different IOL combinations.

Precise IOL selection

More accurate choice

Wide cylinder range

The right solution for your toric IOL implantation.

The wide choice of ZEISS toric lenses available enables you to achieve excellent refractive outcomes – even in challenging cases.
Correcting astigmatism, in conjunction with cataract removal and IOL implantation, provides the opportunity to significantly improve the quality of life for more patients.

ZEISS AT LARA® toric 929M/MP
ZEISS AT LISA® tri toric 939M/MP

Trifocal, bitoric, aberration-correcting

AT LISA® tri toric 939M/MP from ZEISS

Astigmatism correction with the highest level of spectacle independence enables patients to see clearly at all three distances without visual aids.

  • For complete spectacle independence
  • Most widely used trifocal bitoric IOL in the world
  • Proven1 rotational stability thanks to 4-haptic design

EDoF, bitoric, aberration-neutral

AT LARA® toric 929M/MP from ZEISS

Correcting astigmatism in patients who want a high degree of spectacle independence combined with less visual side affects (halo and glare):

  • A wider range of focus than other EDoF IOLs2
  • Spectacle independence for intermediate and far distances
  • Fewer visual side effects than with multifocal IOLs
  • Aberration-neutral aspheric design for optimized contrast sensitivity
  • Fewer visual side effects than with multifocal IOLs2
  • Proven1 rotational stability thanks to 4-haptic design

Monofocal, bitoric, aberration-neutral


Correcting astigmatism precisely and achieving spectacle-free distance vision:

  • Easy to rotate thanks to convenient 4-haptic design
  • Advantages of a bitoric design3
  • Proven1 rotational stability thanks to 4-haptic design

Precise IOL selection with nearly 2000 toric IOL options available

The ZEISS toric IOL portfolio offers a wide variety of near, intermediate and far vision correcting IOLs. Reaching from Monofocal toric to EDoF toric to Trifocal toric intraocular lenses.

More accurate choice with small 0.5D cylinder steps

ZEISS toric IOLs are offered in small 0.5D incremental increments steps in cyl, sphere and spherical equivalent, designed to enable a more accurate choice of toric IOL, based on the patient‘s individual needs.

One of the widest cylinder ranges available with a cylinder range of up to +12 D

The wide choice of cylinder range available enables us to provide the right choice of toric IOLs even in cases with higher cylinder and diopter requirements.

ZEISS toric IOL with Z CALC


A proprietary algorithm specifically designed for ZEISS IOLs. Z CALC predicts immediate post-operative refraction data and supports the selection of ZEISS toric & non-toric IOLs by calculating IOL power.

Z CALC takes posterior corneal astigmatism into account – either by using ZEISS IOLMaster TK® value readings or with the Z CALC Nomogram. Use Z CALC and receive precise calculations on target correction to choose the most suitable toric or non-toric ZEISS IOL for your patient.
