ZEISS IOL Master 500

The ZEISS IOLMaster® 500 is the gold standard in optical biometry
with more than 100 million successful IOL power calculations to date.
With the new version of the ZEISS IOLMaster 500, you get a piece of
cutting-edge technology that points the way to
the future of optical biometry.

Optimize refractive outcomes
Any intraocular lens calculation is only as reliable as the lens constant it is
based on. More than 40,000 sets of patient data created with the
ZEISS IOLMaster are the basis of more than 200 optimized lens constants in
the User Group for Laser Interference Biometry (ULIB) website –
absolutely unique in the industry.1 Together with its one-of-a-
kind distance independent telecentric keratometry and the exclusively
integrated Holladay 2 formula, the gold standard in
optical biometry helps you optimize your refractive outcomes.2

Markerless toric IOL alignment
The Option Reference Image is the starting point of a
markerless toric IOL workflow. An image of the eye is
taken along with the keratometry measurement.
Both reference images and keratometry data are transferred to
the ZEISS CALLISTO eye® computer-assisted surgery system.
Finally, all data needed for precise5 and markerless toric IOL alignment is
injected into the eyepiece of the surgical microscope from ZEISS.

Advanced measurement of challenging eyes
The true test of a biometer is its performance with 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 biometry
devices.3 Even with staphyloma, pseudophakic and silicone-filled eyes,
the ZEISS IOLMaster 500 measures along the visual axis, yielding the
relevant axial distance. And with its Haigis-L formula on board the
ZEISS IOLMaster 500 is dedicated to myopic and hyperopic post-LVC cases.

Proven toric outcomes
The results of a meta-analysis of 28 published clinical papers covering more
than 1900 cases show that the reported clinical outcomes for the
ZEISS IOLMaster with regard to residual astigmatism “[…] exceed,
or are at least as good as those using manual or automated keratometry.”4

Ease of use
A well-designed user interface, plausibility checks, distance-independent
measurements and an up to 4 times faster reading compared to
other optical devices lead to a one-of-a-kind usability and
reduced chairtime.6 A difference you, your team and
your patients will notice every day.
