Abstract:
A method for diagnosing and analyzing the cornea of an eye, said method being performed with the aid of a computer system including a graphic display device, said method comprising the steps of:running a topological modeling computer program on said computer system;reading into said computer system data representing sampled points on a corneal topography map of the surface of the cornea of the eye, said map being of the type produced by a corneal topography scanning machine;utilizing said data in said computer program, to produce a surface model of at least a complete working area of said cornea which closely represents the surface of the cornea in three dimensions as a smooth, free-form surface such that any portion of the surface on said surface model can be manipulated in said computer system in the same manner as an actual surface; anddisplaying at least a portion of said surface model on said graphic display device.
