Abstract:
A method for diagnosing, analyzing or treating the cornea of an eye, said method being performed with the aid of a computer system running a topological modeling computer program which, making use of sampled points on the cornea for which the coordinates are known relative to a reference plane, produces a surface model of said cornea which closely represents the surface of the cornea, said method comprising the steps of:modifying the shape of the surface model enough to change the radius of curvature at a plurality of selected points to achieve a correction in vision indicated to be necessary by an eye test, without introducing substantial changes in shape that are not associated with changing the radius of curvature, to produce a corrected surface model; and at least one of: viewing the surface model or the corrected surface model on a display device; and utilizing the corrected surface model to control the laser ablation of the cornea.
