IOLMaster moment

The moment you trust the experience of 100 million IOL power calculations.

This is the moment we work for.


IOLMaster 500

Defining biometry

Distance-independent keratometry

with the ZEISS IOLMaster 500

The ZEISS IOLMaster 500 is the only optical biometer that uses a smart optical configuration that allows telecentric and thus distance-independent keratometry.
