ZEISS IOLMaster 500 Trusting the experience of 100 million IOL power calculations

The IOLMaster® 500 from ZEISS is the gold standard in optical biometry, with more than 100 million successful IOL power calculations to date. The ZEISS IOLMaster 500 is a great choice for cataract surgeons looking for a reliable, fast and easy-to-use optical biometer for measurements they can depend on.

Refractive outcomes you can trust

The ZEISS IOLMaster is the only optical biometer to feature distance-independent telecentric keratometry.

It enables robust and repeatable measurements and shows excellent agreement with manual keratometry while achieving higher precision.1 In combination with a wide variety of established formulas, you can achieve refractive outcomes you can trust.2

ZEISS IOLMaster 500: Fast and easy to use

Fast and easy to use

A well-designed user interface, plausibility checks, distance-independent measurements and a reading that’s up to 4 times faster compared to other optical devices provide outstanding usability and reduced chair time.3 You can measure both eyes in less than 60 seconds4. A difference you, your team and your patients will notice every day.

Advanced measurement of challenging eyes

In denser cataracts the ZEISS IOLMaster 500 achieves a measurement success ratio that is up to 20% higher than that of other optical biometers5, allowing a cataract penetration rate of more than 93%6. Even with staphyloma, pseudophakic and silicone-filled eyes, the ZEISS IOLMaster 500 measures along the visual axis. And with its Haigis-L formula, the ZEISS IOLMaster 500 allows IOL calculation for myopic and hyperopic post-LVC cases.

Precise and efficient markerless toric IOL alignment7, 8

The ZEISS IOLMaster 500 is an integral part of the ZEISS Cataract Suite. A reference image is acquired and used for intraoperative matching with the live eye image during cataract surgery. Manual marking steps can be skipped altogether for efficient8 and more precise7 toric IOL alignment with reduced residual astigmatism.9
