Anterior best fit sphere –Is it a better starting point to fit rigid gas permeable contact lens in penetrating keratoplasty eyes?–A clinical observation

Purpose: Rigid gas permeable (RGP) contact lens fitting after penetrating keratoplasty (PK) is challenging due to significant irregular astigmatism. The aim of the study was to identify a corneal topography parameter for predicting the initial base curve (BC) of RGP contact lens in post PK eyes.
