Patent ID: 8801634

Claim:
For use with a surgical tool, an apparatus comprising: a controller comprising a processing device, the controller operable to: (i) receive eye measurements that measure portions of an eye of a patient; (ii) use the eye measurements to create a mathematical model of the eye; (iii) determine from the mathematical model of the eye a location, within scleral tissue of the eye, of a scleral pocket that is to receive a scleral prosthesis; and (iv) output the determined location; wherein the controller is operable to determine the location of the scleral pocket by determining from the mathematical model a location of a lens equatorial plane of the eye and where a projection of the lens equatorial plane actually intersects a sclera of the eye; and wherein the controller is operable to determine the location of the lens equatorial plane by multiplying a thickness of a lens of the eye by an empirical percentage, the empirical percentage based on an age of the patient.
