Abstract
For use with a surgical tool for making incisions in the sclera of an eye to form a scleral pocket to receive a scleral prosthesis, a system and method is disclosed for determining a position on the sclera for locating the scleral pocket. The system and method determines an optimum location for the scleral pocket. The system and method determines a location on the sclera that represents the intersection of the lens equatorial plane with the external surface of the sclera. The front of the scleral pocket is placed at a location that is four hundred fifty microns posterior to the intersection of the lens equatorial plane with the external surface of the sclera.
