SYSTEMS AND METHODS FOR ANALYSIS OF CORNEAL TOPOGRAPHY WITH CONVEXITY MAP

摘要

Systems (10, 30, 70, 120, 140, 160) and methods provide convexity map data (122) associated with captured surface image data of a cornea. The convexity map data (122) is determined by transforming an elevation map data set (146) into a convexity map data set (122). Convexity is computed as the negative o f the Laplacian of the local elevation. One or more statistical parameters can be associated with the convexity map data set (122) and employed to derive indices (128). The indices (128) can be utilized to diagnosis a corneal condition 130.
