      STUDY OF THE ANATOMICAL CHANGES INDUCED BY NIGHTTIME RIGID GAS PERMEABLE CONTACT LENSES IN A 1-YEAR FOLLOW UP STUDY (Abstract): Purpose of our study is to analyze the anatomical changes of corneal curvature measured by corneal topography to have a better understanding of the mechanism implicated in myopia control with rigid gas permeable (RGP) contact lenses. We performed a 1-year prospective study on 75 young myopic patients wearing nighttime reverse geometry lens. Flattening of the sim K values were observed throughout the treatment following one year with no significant changes after the first month. Comparing our results with those in the literature, we concluded that reshaping the cornea with RGP lens by flattening the anterior curvature, next to the changes in epithelial thickness with rapid onset and reversibility after the lens is removed, is responsible for the decrease in refractive defect encountered in orthokeratology.
