This document discusses corneal topography, which is the examination and mapping of the shape and curvature of the cornea. It describes different techniques for measuring corneal topography including keratometry, photokeratoscopy, and videokeratography. It outlines the major regions of the cornea and indices used to characterize topography maps. Examples of topography patterns are shown for normal, astigmatic, and diseased corneas. Clinical applications of topography including refractive surgery planning and evaluation, contact lens fitting, and diagnosing corneal conditions are also summarized.Read less
