Abstract
A method of lamellar corneal graft implantation is disclosed herein. In one or more embodiments, the method includes the steps of: (i) modifying a genetic component of a lamellar cornea or other tissue of an animal so that the lamellar cornea or other tissue of the animal can be used for human transplantation; (ii) decellularizing the lamellar cornea or other tissue ex vivo using chemical means; (iii) modifying a shape of the lamellar cornea or other tissue before or after transplantation; and (iv) applying a photosensitizer and ultraviolet radiation to the lamellar cornea or other tissue so as to crosslink collagen and intercellular proteins of the lamellar cornea or other tissue, kill the cells exposed to the photosensitizer, and eliminate an immune response by a host to the implanted lamellar cornea or the tissue.
