Paper Abstract

Currentmethods ofdetermining the shape and elevation ofthe cornea!surface are inadequate both in terms ofaccuracy and extent. Much of the corneal surface is missed by these methods -particularilythe critical center and most of the periphery. All current measuring techniques assume this surface to be spherical -which it is not. Mathematical assumptions have been employed to reconstruct the surface. These assumptions fall short of the accuracy required for realistic assessment of the effect of external influences on corneal shape. Modern surgical methods designed to modulate the corneal surface curvature or alter the refractive state of the eye demand precise measurement of this surface -the main refractive element of the human eye. Single side-band holographic techniques provide the means whereby this demand can be realized. Surface elevations in the sub-micron range can be readily imaged with this technique.
