Blind woman's tooth helps her see again
After nine years of blindness, a Mississippi woman can now see after surgeons used one of her teeth to repair her eye.
Doctors at Bascom Palmer Eye Institute used the tooth to build a structure that allows a small tube to bring light rays into her eye. They say it's the first time the procedure has been used in the U.S.
Kay Thornton now has 20-70 vision. Doctors are hopeful the same technique can help U.S. soldiers who've been blinded in battle.
