Well this is interesting. Apparently there's a type of eye surgery that involves implanting a TOOTH into your eye, using it as a scaffold support to hold a plastic lense and preventing rejection by the body.
The picture of the eye post surgery is wild.
Tooth-in-eye surgery. Who thinks up these things. Incredible.
