1. A system for simulating a reshaping of a model cornea which comprises: a computer programmed with a finite element model comprising a plurality of elements, wherein a first group of elements are pre-programmed to simulate biomechanical characteristics for Bowman's capsule of the cornea and a second group of elements are pre-programmed to simulate biomechanical characteristics for a stroma of the cornea, and further wherein the pre-programmed elements of the first and second groups are established for the finite element model according to diagnostic corneal data; a first computer means connected to the finite element model for minimizing designated biomechanical characteristics on at least one selected element; and a second computer means electronically connected to the finite element model for measuring a reshaped model cornea in response to operation of the first computer means.
