Recently, a man's sight was returned to him
after losing it for 12 years. How did he do it? Surgeons drilled a hole through one of his canines, put a lens in it, and implanted the construct in his eye.
The specific surgery is called Osteo-Odonto-Keratoprosthesis
and was first pioneered in Italy in 1963. Essentially, a tooth and a small portion of the jaw is removed from the patient. A small hole is drilled into the tooth and a lens is attached inside. The tooth construct is implanted in the cheek to allow it develop a blood supply, and then later is implanted into the eye. Despite how unwieldy this procedure seems, it has a shockingly high success rate over time. In this survey
of 181 patients, 85% retained functional use of their eye after 18 years, with approximately 55% retaining the best postoperative functionality.
