The invention contemplates instrumentation to aid in performing refraction-corrective surgery on the conrea, (1) by determining the topography of the anterior surface of the cornea, the determination being in the form of digitized data entered into computer storage, (2) by determining the local thickness of the cornea along multiple axes, the determination being also in the form of digitized data entered into computer storage, and (3) by providing a CAD/CAM display of both categories of data, correlated as appropriate for the surgeon\s selective display ...
The method of using a digital computer to correctively improve optical properties of an eye by changing the curvature of the anterior surface of the cornea in approach to a computer-stored digital definition of an idealized three-dimensional anterior-surface curvature, which method comprises: (a) determining and digitizing the topography of the anterior surface of the cornea as a three-dimensional curved surface, and entering digitized topography data thereof into computer storage; (b) creating from said topography data and from said stored digital defin...
