Abstract

The accuracy of video keratoscopes on non-rotationally symmetric surfaces has not been established. In this work, we test the performance of one manufacturer's instrument (Computed Anatomy TMS-1, New York, NY) on a set of 5 precision toric reference surfaces. These surfaces have a base radius of curvature (ROC) of 7.80 mm, which corresponds to an equivalent comeal power of 43.25 D.
