Transplantation of the cornea.
Corneal transplantation is the most widely practised form of allografting in clinical practice. The operation is used to correct developmental abnormalities of corneal shape such as keratoconus, to overcome opacities of the cornea, to relieve pain and to mend perforations. Corneal transplantation is generally successful but contrary to popular belief, corneal grafts can be rejected. This is a particular problem for patients treated for the sequelae of inflammatory disease. The relative importance of measures such as systemic immunosuppression and tissue typing is less in corneal transplantation than in other forms of clinical allografting. Overcoming rejection, achieving the best optical configuration in a graft, and increasing the number of donor corneas available for transplantation represent the main avenues for achieving improvements in corneal transplantation.
