BESST II IOL POWER CALCULATOR                                    

 
 

Developed by Dr Edmondo Borasio and Julian Stevens' Team at Moorfields Eye Hospital, BESSt Formula allows unprecedented levels of accuracy in the calculation of IOL power after Laser Refractive Surgery (LASIK, PRK, LASEK, Epi-LASIK) for Myopia or Hyperopia by using measurements taken with the Oculus Pentacam™ and without any knowledge of pre-refractive surgery information.


BESSt formula only requires the following post laser refractive surgery information: Pentacam’s Anterior and Posterior radii of curvature, Central Corneal Thickness and Axial Length. Now even more accurate with the BESSt 2.0 algorithm. Read more.


NEW - LATEST PC VERSION (2.0.0.76):

Supporting Direct Importing of values between Pentacam and BESSt

  1. Stop wasting time entering the values manually! With the latest Direct Import version, all Pentacam values are directly exported to BESSt with a single click of the mouse. The only requirement is that BESSt II IOL Power Calculator and Pentacam are installed on the same PC. It also works for the Off-line version. Read more.
