Abstract
A computerized system which enables the contact lens fitter to select a contact lens by specifying its 'base curve' and diameter and then to obtain a visual representation of how that lens would fit the cornea of a specific patient using a simulation of the traditional fluorescein dye procedure. The patient's corneal contours are electronically stored, having been ascertained, for example, using the image scanning technique disclosed in U.S. Pat. No. 4,863,260. The contour of the contact lens is positioned to a predetermined point over the contour of the corneal surface and iteratively rotated about two axes to establish a minimum average clearance. At this point, the clearance is depicted by a color display analogous to that which would be obtained using the actual contact lens on the patient's cornea with the fluorescein dye.
