Claim:
1. A method of preventing rejection of an implant in the eye, comprising: forming a flap in the cornea of the eye, wherein said forming a flap includes cutting the flap with one of a micro-keratome and a femto-second laser, the flap being cut so as to have a diameter between 2 mm-12 mm and a thickness of 50 microns to 400 microns; raising the flap so as to expose stromal tissue of the cornea; applying a cross linking material in the form of Riboflavin to the stromal tissue of the cornea under the flap; inserting an implant under the flap so as to overlie the stromal tissue of the cornea; covering at least a central portion of the implant with the flap; and after said inserting the implant under the flap, cross linking corneal tissue vulnerable to enzymatic degradation surrounding the implant to decrease the vulnerability of corneal tissue surrounding the implant to enzymatic degradation, to make the corneal tissue surrounding the implant less likely to be invaded by migrating cells, and to prevent encapsulation around the implant.
