ZEISS IOLMaster 500

The Zeiss IOLMaster 500 remains the gold standard in optical biometry.
Used in more than 100 million successful IOL calculations worldwide,
it offers fast and accurate axial length, keratometry and
anterior chamber measurements.
Enhanced cataract penetration and proven toric outcomes streamline
pre‑operative planning, while integrated formulas (SRK/T, Holladay 2,
Haigis, Hoffer Q and more) support nearly any patient.
Its intuitive interface minimizes chair time and training, making it an essential tool
for cataract surgeons. GMG refurbishes and calibrates each IOLMaster 500 to
factory standards, delivering reliability and sustainability at a reduced cost.

The IOLMaster 500 from ZEISS is the gold standard in optical biometry,
with more than 100 million successful IOL power calculations to date.
The 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.
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.

This IOL Master 500 comes equipped with:
– Power table with keyboard -Dust cover
– Printer

Features
High Speed Biometry
Minimize acquisition and chair time by performing accurate measurements
quickly. In the Dual Mode, axial length and keratometry are captured in
one measurement. Changeover between modes is completely automated and
does not require any user interaction. The average time needed to take a reading
on the IOLMaster 500 is up to 4 times faster compared to other optical devices.

Excellent Cataract Penetration
The IOLMaster 500 achieves a measurement success ratio that is up to
20 percent higher than that of other optical biometry devices.
The underlying Composite Signal evaluation not only significantly increases the
fraction of cataracts measurable with optical technology,
it also greatly increases signal-to- noise values – a measure of
the outstanding reliability of the data the IOLMaster 500 provides.

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.
A difference you, your team and your patients will notice every day.

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.

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.

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.

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.
