Optimization of lens constants is often recommended for accurate IOL power calculation1. Such optimized constants for the calculation of intraocular lens power are published 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.
IOL constants can be entered manually into the ZEISS IOLMaster or imported from the file provided below. This file is a compilation of commonly used IOLs with their constants and available powers.2
Download the IOL constants onto the following media:
- CD R(W) for ZEISS IOLMaster version 4.xx
- USB flash drive for ZEISS IOLMaster 500 and ZEISS IOLMaster 700
