Abstract

PURPOSE: To compare the anterior and posterior corneal curvature in eyes with previous radial keratotomy (RK) to normal unoperated eyes. METHODS: In this retrospective observational case series, 29 eyes from 29 consecutive patients were analyzed and compared to a control group of 71 unoperated eyes. Corneal imaging was obtained by a rotating Scheimpflug camera (Pentacam, Oculus Optikgeräte GmbH). Anterior and posterior corneal curvature radii were measured at the 3-mm zone. RESULTS: The mean anterior and posterior corneal radii were 9.54±0.89 and 8.54±1.01 mm, respectively, both values being significantly higher than in the control group (7.81±0.28 and 6.40±0.24 mm, respectively, P
