B-OCT module support different IOL constants databases standards. User can select preference to use IOL manufacturer constant or use optimized constants for the calculation of intraocular lens power. Optimized constants are published by Ulib or recently by  IOLCon (Steinbeis Vision Research) on their website https://iolcon.org/. These constants are based on actual surgical data and are provided by IOL Con as a starting point for individual constant optimizations. Our module supports the IOL Con database standard so that you can always keep your library up-to-date. User has choice to use select preferences for IOLcon/Ulib or Manufacturer optimized constants. The current users can update IOL constants directly from iolcon.org or provide own contants.
