ZEISS IOLMaster 500Trusting the experience of 100 million IOL power calculations 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.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. Refractive outcomes you can trust 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. In combination with a wide variety of established formulas, you can achieve refractive outcomes you can trust 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.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.Specifications Measurement range:Axial length 14 – 38 mmCorneal radii 5 – 10 mmAnterior chamber depth 1.5 – 6.5 mmWhite-to-white 8 –16 mmIOL Calculation Formulas:SRK II, SRK / T, Holladay 1 and 2, Hoffer Q, HaigisClinical history and contact lens fitting method for calculation of corneal refractive power following refractive corneal surgeryHaigis-L IOL calculation for eyes following myopic / hyperopic LASIK / PRK / LASIK surgeryCalculation of phakic anterior and posterior chamber implantsOptimization of IOL constantsDisplay Scaling:Axial length 0.01 mmCorneal radii 0.01 mmAnterior chamber depth 0.01 mmWhite-to-white 0.1 mmThis IOL Master 500 comes equipped with:6 Months WarrantyExternal Printer (Optional)Keyboard with Mouse PadDust Cover
