Patent ID: 8911083

Claim:
A system for facilitating contact lens design before manufacture, the system comprising: an input unit configured for input of model design parameters based solely on at least one from a group consisting of model designs and model measurements, and a processing unit for calculating a post-lens pressure profile based on the model design parameters, the post-lens pressure profile is calculated with respect to a model representation of a standard eye, wherein the post-lens pressure profile is calculated by applying a frictionless sliding contact approximation between the model contact lens and the model eye, wherein the frictionless sliding contact approximation comprises a small distance separation between the lens and the eye; wherein the processing unit is arranged, in use, to perform a finite element model calculation allowing for large deflection/non-linear geometry effects in the deformation of a model lens shape, wherein the finite element model calculation utilizes solid elements for modeling the lens shape, wherein the model lens and eye parameters are defined by applying a pressure evenly across the contact lens surface, examining pressure peaks identified from the pressure application, evaluating continuity of the pressure peaks and repeating the process if not acceptably continuous, and analyzing the height of the pressure peaks.
