<P>PROBLEM TO BE SOLVED: To more precisely analyze keratopathy case by making further improvement in classification of keratopathy cases. <P>SOLUTION: This corneal topography analysis system includes: an input means for inputting corneal shape data; and an analysis means for determining a plurality of indexes characterizing the corneal topography on the basis of the input corneal shape data to determine at least one of the following keratopathy cases as a characteristic inherent to the keratopathy case classification using the determined indexes and the neural network: normal cornea; myopic refraction surger; hyperopic refraction surger cornea; corneal astigmatism; penetrating keratoplastry; keratoconus; keratoconus suspect; pellucid marginal degeneration; and other corneal topography cases. The analysis means calcurates acuuracy for at least one case of at least one corneal topography case classification determined. <P>COPYRIGHT: (C)2006,JPO&NCIPI
