Industry-Defining Technology

A true standout among optical biometers, the ZEISS IOLMaster® 500 features:

Distance-independent telecentric keratometry – The ZEISS IOLMaster® 500 enables robust and repeatable measurements that are consistent those achieved with manual keratometry, but much more precise.

A high measurement success ratio in dense cataracts – With a cataract penetration rate of more than 93%, this outstanding optical biometer measures along the visual axis, even with staphyloma, pseudophakic and silicone-filled eyes.

Precise and efficient markerless toric IOL alignment – An integral component of the ZEISS Cataract Suite, the ZEISS IOLMaster® 500 acquires a reference image that can be used for intraoperative matching with the live eye image during cataract surgery, eliminating the need for manual marking.
