Patent ID: 7370969

Claim:
A corneal topography analysis system comprising: an input unit for inputting corneal shape data of an eye to be examined; an analysis unit that determines plural indexes characterizing topography of the cornea (corneal topography) based on the input corneal shape data, the analysis unit further judges corneal topography of the eye, including keratoconus (KC), keratoconus suspect (KCS) and pellucid marginal degeneration (PMD), using the determined indexes and a neural network; and a display unit that displays a judging result of the corneal topography by the analysis unit, wherein the neural network is trained so as to input corneal topography having been clinically judged in advance, including keratoconus, keratoconus suspect and pellucid marginal degeneration, determine weighted coefficients for each corneal topography and output the judging result of the corneal topography.
