Description

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.

Available now for sale and in excellent condition, for each refurbished unit from GMG is thoroughly tested, offering sustainable eye‑care technology for all your indispensable modern ophthalmic practices assets .

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.
