Abstract
Several techniques have been used to determine the radius of curvature of the cornea. In this article, we describe the use of a method obtained trough ray analysis, based in geometrical analysis and lateral magnification equation. A pattern of an increasing point was displayed in a flat screen monitor; images of this point were captured for a test sphere with a CCD camera. The obtained data was then processed for the calculation of the sphere curvature. The experimental setup is presented.
