* The A-constant is presented as a starting point for the lens power calculation. When calculating the exact lens power, it is recommended that calculations be performed individually, based on the equipment used and operating surgeon’s own experience.
** These optimized constants for the calculation of intraocular lens power published by IOLCon on their website: https://iolcon.org are calculated from 913 clinical results for Vivinex™ Gemetric™ IOLs as of June 10, 2024. These constants are based on actual surgical data and are provided by IOLCon as a starting point for individual constant optimizations.
