IOLMaster 500 from ZEISS

Defining biometry

  • Highlights

    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.

    Unique ULIB data set

    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

    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

    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, IOLMaster 500

    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

     

    Toric IOL studies report excellent outcomes using IOLMaster keratometry

    Ease of use

    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.

    Option Reference Image

    For markerless toric IOL alignment

    The new Option Reference Image supports a markerless toric IOL workflow. It references the patient’s astigmatic axis relative to his/her eyeball position using small blood vessels on the eye as landmarks. Reference image and keratometry data are transferred to the ZEISS CALLISTO eye® computer-assisted cataract surgery system. Finally, all data needed for precise1 and markerless toric IOL alignment is injected in color and high resolution into the eyepiece of the surgical microscope from ZEISS.
