ZEISS IOLMaster 500

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.

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

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.

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.

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
