Surgeons at Sussex Eye Hospital performed an original operation that uses the rare osteo-odonto-keratoprosthetics (OOKP) technique. The method of restoring vision with the help of a patient's tooth was invented in the early 1960s.

This is a very complex operation. First, a tooth with a small amount of attached bone is removed from the patient. After processing the biopreparation, it turns into a thin plate, to which a plastic lens is attached as a replacement for the damaged lens of the eye. A flap of mucous membrane taken from the cheek is attached to the lens tooth, after which the implant is implanted into the cheek.

After a certain time, approximately 4 months, the implant is placed in the cornea of ​​the eye.

Such operations are very rare and, in terms of the quality of the returned vision, are inferior to the more usual corneal transplantation of the eye. But the use of a tooth can be useful in the case when donor tissue transplantation is impossible, or for promising cyberplants that need a "chassis" that cannot be rejected by the patient's body. Despite the long rehabilitation period, as well as the insignificant risk of rejection or glaucoma if the material was taken from another donor, OOKR operation, in general, has a good prognosis.

In a patient at the Sussex Eye Hospital, Jan Tibbets, who completely lost his sight as a result of an accident, thanks to OOKR, surgeons were able to partially (40%) restore vision in the right eye.
