[quote] The procedure - called Osteo-Odonto-Keratoprosthesis (OOKP) - involves the reconstruction of a new eye using a tiny plastic lens and one of the patient's own teeth. The lens is inserted into a hole drilled through the tooth, which is later implanted in the eye. And as long as the retina is still functioning, the lens then provides a new window through which the patient is able to see. Remarkably, because the tooth belongs to the patient, the body does not reject it. The treatment is only suitable for certain types of blindness and can only be performed by one surgeon in Britain - Christopher Liu at the Sussex Eye Hospital in Brighton. Professor Liu said: "OOKP is not guaranteed to restore sight but it does have a high success rate. "Patients who have the surgery are often able to see immediately and the quality of sight can be extraordinarily good.

That and the people that come up with this stuff.
