ABSTRACT:
A system for treating vision disorders is disclosed. The system includes a heating device able to heat predetermined areas of the corneal tissue of an eye. The energy for heating is typically generated in the form of laser light or infrared that cause the tissue at that predetermined area to heat and shrink. The shrinkage shifts a plug or portion of the cornea with respect to the remainder of the eye to change the shape of the corneal surface and correct the problematic refractive error. A heat absorption modifier is used to avoid damage to the epithelial layer as energy is passed therethrough.
