ZEISS Cataract Suite markerless

Products designed to work together for
markerless toric IOL alignment

Integrated. Precise1. Markerless.

IOLMaster 500

IOLMaster 500

Precise1 alignment starts with excellent biometry from the ZEISS IOLMaster® 500. The new Option Reference Image is the starting point of a markerless toric IOL workflow.



Building on gold standard biometry.



Connecting you and your devices, the computer assisted cataract surgery system ZEISS CALLISTO eye® creates the overlays for the surgical microscope using data retrieved from the data management system ZEISS FORUM®.


Designed to work together.



All the information you need is injected into the eyepiece of the surgical microscopes of the ZEISS OPMI LUMERA® family2 to assist in precise1 toric IOL alignment.




Building on gold standard visualization.

Biometry and reference image

Skip pre-operative corneal marking and avoid detours

IOLMaster 500 with the new Option Reference Image
automatically acquires the reference image in case of astigmatism during routine biometry. An image of the eye is taken along with the keratometry measurement, all with one device. Both reference image and keratometry data are transferred to the CALLISTO eye computer assisted cataract surgery system. The image is later used for intra-operative matching with the live eye image. No pre-operative corneal marking. No additional measurements for toric IOL alignment are needed later. One device, one click, all the data.
