title: Imaging of the cornea.
abstract: The aim of the LSU Eye Center Corneal Topography Project was to apply computer analysis to keratoscopy and develop graphic presentation methods to provide accurate and easily assimilated information regarding the status of patient corneal topography. The analysis contains four diagrams: a plot of the raw keratoscope data for quality control, a three-dimensional wire model of corneal surface power distribution, a plot of dioptric point surface powers, and a color-coded contour map of corneal surface powers. While the analysis uses a current generation 11 ring keratoscope for producing keratoscope photographs, it can be adapted to newer keratoscopes, which promise to give broader coverage of the corneal surface. Examples of normals and several surgical patients will be shown, including cases in which the method has pointed to potential refinements in the theory and application of refractive surgical techniques.
