IOL master® by Zeiss
The ZEISS IOLMaster® enables precise and reliable intraocular lens (IOL) calculations to be made based on optical biometry, so that patients undergoing cataract surgery are more likely to achieve a successful refractive outcome. More than 100 million successful IOL power calculations to date have been made with the IOLMaster worldwide. The scans are obtained without needing any contact with the eye, have in-built plausibility checks to ensure reliability, and only take a few seconds to acquire. The IOLMaster® is also proficient at measuring challenging eyes, such as in patients who have a staphyoma or silicone oil-filled eyes following retinal surgery. It also contains many formulae within its software including Holladay 2 and Haigis-L, the latter being useful in the calculation of IOL power in patients who have previously had laser vision correction.
