*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 ULIB on their website: http://ocusoft.de/ulib/c1.htm are calculated from 319 clinical results for model 250/251 as of October 31, 2016. These constants are based on actual surgical data and are provided by ULIB as a starting point for individual constant optimizations.
