Abstract

Machines for the measurement of corneal topography typically produce a colored topographic map of the mean curvature of the cornea. (1). From the examination of a number of such maps of normal corneas it has been found that the normal cornea is most curved at its apex and flatter in the periphery. By contrast, a cornea flattened by corneal surgery will typically be flatter in its center and steeper in the periphery (2).
