Eyeteeth (literally)

From the department of “say what?”:

For the first time in the U.S., a blind woman’s sight was restored by fitting a plastic lens into a tooth from her mouth, and implanting the combination into her eye. The patient, a 60-year-old who had been blind for nine years, now has 20/70 vision that might further improve as she recovers from the surgery

From the WSJ. Apparently the Italians have been doing this since 1963.

What tooth do they use? You guessed it–the eyetooth.
