Abstract
The present invention provides a method of corneal transplantation and a corneal structure resulting from such transplants. According to this method, a thickness of a patient's cornea is removed to define a bore through the cornea, this thickness of corneal tissue defining a cap consisting of an outer thickness of tissue and a plug of an inner thickness of the tissue. An ocular implant sized and shaped similarly to the plug is then placed within the bore and surgically attached. The cap of the patient's own tissue is then placed in the bore and surgically reattached. The patient's cornea may be marked before removal of the tissue and this marking may be used to properly reorient the cap upon placing it in the bore for reattachment. The corneal structure of the invention includes an ocular implant sized to fit closely within a bore through a patient's cornea, the implant being attached to the cornea, and a cap formed from an outer thickness of the patient's cornea.
