I don't think this needs any setup at all.

This is just, it's just bizarre.

It's just that technology has advanced so far that you just, you almost question the doctor that thought how to remedy this solution.

Because it's so bizarre.

Because you keep saying technology, but to me it's almost like you're going backwards a little bit and just trying to put it together.

You know what I'm saying? Anyway, it'll make sense what you hear.

Play it, play, play it. So curious.

8-7.

Kate Thornton has good reason to smile.

Don't cheat on me.

Blind for the past nine years, the 60-year-old just got her sight back.

When you can see again, it's amazing.

But it's the operation, the first of its kind in the United States, that is mind-boggling.

Doctors at Baskin-Palber Eye Institute in Miami extracted a tooth,

drilled a hole in the tooth and fitted it with a plastic lens, and then inserted the tooth in her eye.

What?

You heard that correctly. They put the tooth in her eye.

I thought it was the silliest thing I'd ever heard of in my life.

You know, take a tooth out of my mouth, put it under here, right up under the eye, let it incubate.

Then we're going to take it out, and then we're going to put it in your eye, and you'll be able to see.

And as hard as that was to believe, now?

It's true.
