Abstract

We propose a method to estimate “fudge factor” in the selection of IOL power for post-myopic LASIK patients undergoing cataract surgery by considering the difference between subjective refraction (SR) and autorefraction (AR) and to also compare the predictability of two popular regression formulae: SRK-T and Haigis.
