Blind for a decade, Englishman Martin Jones is finally able to see again – through a piece of tooth implanted in his eye. Appropriately, the tooth used was a canine, otherwise known as an ‘eyetooth’. Doctors took a piece of Jones’ own living tooth, placed a man-made lens into its core and implanted it under his eyelid where tissue grew over it. A flap of skin excised from inside the patient’s mouth was placed over the tooth in Jones’ eye where it acquired its own blood supply. A hole cut in the new cornea allows light to pass through. The procedure has restored sight to over 600 people worldwide.
