Doctors implant tooth into eye to restore sight

I never expected that a blind person would literally give their eye-teeth to see again, but this unlikely sounding swap appears to have finally happened in Miami.

A tooth is removed, an artificial lens placed into it and it is then put over the eye to allow light back onto the retina. A synthetic base for the lens would be rejected by the body, but I imagine any bit of bone might work as well as a tooth.

I heard the patient in the video being interviewed on Radio 5 yesterday evening and despite the Frankenstein approach it’s clearly changed her life. Perhaps it will be toenails for the deaf next?
