Woman's Sight Restored Using Tooth

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, and says she's savoring every moment of vision. Her first sight? Seeing her doctor putting medication into her eye, and noticing a color for the first time. She shouted "It's yellow!"

Doctors are hopeful the same technique can help U.S. soldiers who've been blinded in battle.
