Zeiss IOLMaster 500

This used Zeiss IOLMaster 500 is a widely trusted optical biometer built for precise preoperative measurement ahead of cataract and refractive surgery. It uses partial coherence interferometry to capture axial length, corneal curvature, anterior chamber depth, and white to white measurements without the need for corneal contact, which keeps patient throughput fast and comfortable in a busy ophthalmology clinic. The touchscreen interface and onboard IOL power calculation formulas make it straightforward for technicians to acquire repeatable readings and pass clean data along to the surgeon. Surgical practices and ambulatory surgery centers rely on this unit for its speed and accuracy when planning intraocular lens selection, and its non-contact design reduces the risk of corneal abrasion or infection compared to older ultrasound based biometers. The system supports multiple IOL formulas and can export data directly to compatible surgical planning and femtosecond laser platforms, making it a practical fit for centers that have already integrated digital cataract workflows. Many clinics keep an IOLMaster on hand specifically for its reputation in premium and toric lens calculations. This particular unit has been in clinical service and shows normal cosmetic wear consistent with regular use, but it remains fully functional and ready to be integrated into an existing biometry workflow. It is a sound option for a practice looking to add a proven, high accuracy optical biometer without paying new equipment pricing, and it suits clinics upgrading from ultrasound based systems or adding a second station for higher patient volume.
