Contact lens fitting for post-radial-keratotomy residual myopia

Abstract

PURPOSE: To formulate guidelines for contact lens fitting following radial keratotomy and to achieve a relationship between contact lens fitting parameters and refractive and keratometric parameters. METHODS: Thirty-five eyes of 30 patients who had post-radial-keratotomy residual myopia were evaluated for contact lens fitting. The base curve was selected by 'hit and trial' method until a proper fit was achieved, following which an over-refraction was done and final power of the contact lens obtained. RESULTS: The mean contact lens base curve was 43.04 +/- 1.62 D, which was steeper than the postoperative keratometry by 2.35 +/- 0.74 D. The base curve and the postoperative keratometry were cor..
