Osteo-odonto-keratoprosthesis

Osteo-odonto-keratoprosthesis (OOKP) (also known as 'tooth in eye' surgery) is a medical procedure to restore vision in the most severe cases of corneal and ocular surface patients. It includes removal of a tooth from the patient or a donor. After removal, a lamina of tissue cut from the tooth is drilled and the hole is fitted with optics. The lamina is grown in the patients' cheek for a period of months and then is implanted upon the eye. The procedure was pioneered by the Italian ophthalmic surgeon Professor Benedetto Strampelli in the early 1960s. Strampelli was a founder-member of the International Intra-Ocular Implant Club (IIIC) in 1966.

An operation to graft the OOKP is undertaken in severe pemphigoid, chemical burns, Stevens–Johnson syndrome, trachoma, Lyell syndrome and multiple corneal graft failure. There is a significant risk of anatomical failure of lamina in the long term, estimated at about 19% in a small study, with the main risks being laminar resorption, particularly in allografts, and glaucoma.
