I was wondering where does Hicsoap pulling the constants from, is it from ULIB or another source?
The lens Database built into our program comes with the Lens Constant that has been provided by the MANUFACTURER for IMMERSION Ascan (U/S). In a few common IOLs, we have ADDED the Optical Lens Constant from reputable sources such as ULIB that has included many studies. The Average Difference between the Immersion and Optical Lens Constant is 0.2 mm or 0.3 D.
What's the relationship between PLC, SRG, and MFG?
PLC overrides SRG (Surgeon Entered Constant) overrides MFG (Manufacturers Constant.) There is no way to change this.
