Osteo-odonto-keratoprosthesis (OOKP), also known as "tooth in eye" surgery,[1] is a medical procedure to restore vision in the most severe cases of corneal and ocular surface patients.
Another, bigger study comparing OOKP with the lesser known osteo-keratoprosthesis (OKP) in 145 and 82 patients and follow-up terms up to 10 years yielded the following statistics:[citation needed] Another long-term study of 181 patients puts the chances of retaining an intact OOKP after 18 years at 85%.
[7] In 2022, a retrospective study conducted on 82 eyes with OOKP using original Strampelli technique, showed an anatomical survival of 94% up to 30 years of follow-up.
[3] The procedure was pioneered by the Italian ophthalmic surgeon Professor Benedetto Strampelli[citation needed] in Rome in the early 1960s.
Strampelli was a founder-member with Harold Ridley and Peter Choyce of the International Intra-Ocular Implant Club (IIIC) in 1966.
