ABSTRACT:
An apparatus for correcting the curvature of a cornea of an eye comprises a housing for placement on the cornea for altering the curvature of cornea to extend a portion of the cornea above a predefined plane parallel to a plane tangent to the eye. The apparatus also includes a laser which is positioned to ablate the portion of the cornea which extends above the plane from the side of the cornea. A keratometer is also included to scan the cornea to determine the amount of the cornea extending above the plane.
