Abstract
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 of a corneal region, aspect or section, as the surgeon may deem pertinent to a prospective operation.
