ZEISS IOL Master 500 Optical Biometer

The ZEISS IOLMaster 500 is a trusted biometry solution.
Designed to deliver fast, accurate, and reproducible measurements,
the IOLMaster 500 helps streamline cataract surgery planning and
improve refractive outcomes. With over 100 million IOL power
calculations performed globally,
it's the proven choice for ophthalmic professionals.

Key Features:
Proven Accuracy: Measures axial length, corneal curvature,
anterior chamber depth, and white-to-white distance with
sub-millimeter precision.
Fast Acquisition: Delivers full biometry in less than 60 seconds for
most patients, even those with dense cataracts.
Intuitive Interface: Easy-to-use touchscreen and
guided workflow minimize training time and optimize clinic efficiency.
Advanced Fixation Check: Ensures reliable measurements by
detecting patient fixation, reducing the risk of
incorrect IOL power calculations.
Compatibility: Integrates seamlessly with leading IOL calculation formulas
and surgical planning software.
