TIL that for some people with irreparably damaged corneas, you can pull one of their teeth, drill a hole in it, install an artificial lens, sew it into their cheek (so tissue attaches), then pull it out and stick it in their damaged eye, and ... it works fine!?! www.nbcboston.com/news/health/...

How on earth did they find out that that works?!?

An Italian doctor in the 60s noticed that if something ends up inside a tooth root canal, it will just stay there, and not get rejected. The problem with most implants is rejection; your eye will reject a plastic lens, but not a tooth, and the tooth won't reject the lens, so it acts as a medium

As soon as someone finally gets implant rejection licked, we're in for so many weird surgeries happening. I'm looking forward to it.
