Nine years ago, Sharron Thornton’s hair and nails fell out, while her skin developed a blistering rash. Turns out she was suffering from a very rare condition—know as Stevens-Johnson syndrome—caused by a reaction to a medication. She eventually went blind after the cells in her eye died and left corneal scarring.
While her hair and skin grew back, her eyes remained useless. Her condition devastated her: She thought about suicide, and tried a stem cell procedure, but couldn’t be considered for a cornea transplant. Finally she went on a desperate search for any experimental treatment to cure her blindness.
For the first time in the U.S., surgeons decided to perform a rare procedure called modified osteo-odonto keratoprosthesis, to correct corneal scaring. While the procedure has been done a total of 600 times since the 1980s, it’s still pretty complicated: First the surgeons took Thornton’s tooth and part of her jawbone, and made a hole for the prosthetic lens. Then it got weirder: The surgeons implanted the modified tooth into the woman’s chest and left it there for a few months so the two parts could grow together. And finally, the tooth was implanted into her eye.
CNN reports:
Dr. Ivan Schwab with the American Academy of Ophthalmology told CNN he believes the process is too difficult and the result too disfiguring. There are alternatives that are nearly as good, he added.
“We’ve known about the procedure since the ’80s. It’s been going on for a while,” he said. “We’ve viewed it with some skepticism. It requires a sizable team and several operations. It seems to be reasonably successful on the small numbers that have been done,” though it does bring some disfigurement.
Surgeons doubt the procedure will be common in the U.S. anytime soon. But for Thornton, it gave her a reason to live.

I am still trying to wrap my head around this-her tooth was turned into part of a frame for a kind of internal monocle, if I understand correctly? The disadvantage of using an artificial material instead of part of her body must be the sensitivity of the tissues around the eye.

Do they have a picture of this somewhere? Pretty bizzare. Why did they have to use a tooth?

Here’s a link with pictures of this procedure.
Very odd but with cosmetic additions looks almost normal.
