ABSTRACT:
An apparatus for profiling a cornea of an eye is disclosed which comprises a topography instrument for determining the curvature of the cornea, a computer system for receiving information from the topography instrument for determining whether any areas of the cornea need to be ablated to correct for any abnormalities of the cornea, a diffractive optical element which is constructed based upon the determination of which areas of the cornea need to be ablated, and a beam of radiation being projected at the diffractive optical element for the diffractive optical element to modulate the beam of radiation and direct the modulated beam of radiation at the cornea for ablating the cornea to correct for any abnormalities of the cornea.
