Developed by Dr Edmondo Borasio and Julian Stevens' Team at Moorfields Eye Hospital , London , the BESSt© Formula allows unprecedented levels of accuracy in the calculation of IOL power after Laser Refractive Surgery (LASIK, PRK, LASEK, Epi-LASIK..).

BESSt formula requires Anterior and Posterior corneal radii from the Oculus Pentacam™ and does not require any pre-refractive surgery information. An improved algorithm (BESSt 2.0) has been designed and the software will be released soon. Please visit us again in a few weeks.
