Abstract
One embodiment of the present invention is a method for providing a local average curvature map of an eye that includes: (a) providing elevation data for points on a corneal surface of the eye; (b) selecting a set of elevation data in a neighborhood of each of a number of points on the corneal surface; (c) fitting a geometric figure at each of the number of points using the set of elevation data in each neighborhood; and (d) determining a curvature relating to the geometric figure at each of the number of points.
