ABSTRACT:
An apparatus and method for treating vision disorders is disclosed. The apparatus and method incorporate a cutter which cuts into the corneal tissue of an eye. The corneal tissue proximate the lower region of the cut is then heated by, for instance, a laser which causes the tissue at that predetermined region to shrink. The shrinkage moves the cut plug with respect to the remainder of the eye to change the shape of the corneal surface and correct the problematic refractive error.
