Patent ID: 7909780

Claim:
For use with a surgical tool, a method comprising the steps of: receiving eye measurements that measure portions of an eye of a patient at a controller, the controller comprising a processor; using the eye measurements at the controller to create a mathematical model of the eye; determining at the controller from the mathematical model of the eye a location on a sclera of the eye for making an incision, the incision having a form of a scleral pocket that is capable of receiving a scleral prosthesis, wherein determining the location on the sclera for making the incision comprises: determining a location of a lens equatorial plane with respect to an anterior surface of a lens of the eye, the location of the lens equatorial plane determined by multiplying a thickness of the lens by an empirical percentage, the empirical percentage based on an age of the patient; determining from the mathematical model of the eye a distance between a corneal plane of the eye and the lens equatorial plane of the eye; determining from the mathematical model of the eye a distance from a center of a scleral shell of the eye to the lens equatorial plane; and determining a location on the sclera where a projection of the lens equatorial plane intersects with the sclera; and outputting at the controller the determined location on the sclera for making the incision.
