Earlier quoted context omitted.

You don't need horror movies with such science.

Or at any rate with such headlines. We've adopted the more neutral subtitle now.

The title "For the 1st time in Canada, surgeons put teeth in patients' eyes to restore sight" is much clearer than "Surgery aims to restore sight by implanting a telescopic lens in a tooth".

First, the tooth is put into the eye — used as biocompatible material to hold the lens. Second, the surgery is 60 years old and has something like a 94% success rate after 27 years, so it's hardly fair to say "surgery _aims_ to restore sight". It almost certainly will restore sight. The part that is interesting in this story is that it's an uncommon surgery that is happening only for the first time _in Canada_.

At first I was curious if they'd included any pictures of what it actually looks like, but when I saw the pictures I definitely came to doubt my decision. So for the feint of heart, beware.

Yeah, that is something. Reminds me a bit of the eye worn by Charles Dance's character in Last Action Hero.

This is the first I'd heard of this, and I did some poking around, and came to the conclusion that this surgery is ~mostly obsolete --- which is an answer (for me) to the question of "don't they have a better substance to use as a lens substrate than tooth?"

Why is it obsolete?

Like something out of a Lynch or Cronenberg film. Definitely not what I was expecting

Those are good points. dcminter suggested a different wording, which might have a less agitating effect, so we can try that for a while.
