Optimized Lens Constants for the ZEISS IOLMaster
Highly accurate IOL power calculation requires optimization of lens constants¹. If the lens power calculation is based on IOLMaster measurements, only lens constants optimized for use with the ZEISS IOLMaster should be applied. Optimized lens constants for the calculation of intraocular lens power with the ZEISS IOLMaster are published by the User Group for Laser Interference Biometry (ULIB) on its website. These constants are based on actual surgical data and are provided by the ULIB as a starting point for individual constant optimizations. Carl Zeiss Meditec AG does not create, validate, verify or otherwise confirm that these third party lens constants are correct or appropriate for IOL implantation.
