<p>A process for making a corneal inlay and implanting the inlay in the human eye, the latter comprising the steps of preparing a lens blank; shaping the blank by laser milling or the like; preparing a recess in the cornea of the patient, the recess being adapted to receiving the shaped inlay whereby the exterior surface of the inlay lies flush with the Bowman's layer; and bonding the inlay to the recess by suturing, laser welding, gluing or other appropriate means. The process reduces many previous problems related to handling and reshaping of corneal tissues used in correcting visual impairments. Corneal tissue implants are frequently obtained from recently deceased donor individuals and require freezing in order to cut and reshape it to suit the recipient's needs. The present inventive process reduces prior art problems by producing tissue from solidified collagen or collagen-like materials derived from gelatin or other sources.</p> |
