So these sciency folks have managed to move tooth from the mouth to the eyes but still want to pluck some teeth off to move around some other teeth parked wrongly; and then expect me to have something installed forever to keep them in place, even after all that planned uprooting. Huh.

fwiw in the US, typically even extremely messed up teeth don't require removal to fix with orthodontics. Some ortho places will advocate it because it's easier. But if you get a few quotes in a big city usually someone can do it without pulling.
Wisdom teeth often do require pulling cus they literally don't fit (idk if this is an evolution thing - were people losing teeth normally enough that a new one coming in wasn't overcrowding?)

I think this is an evolution thing but not in that way. I believe when our diets changed due to agriculture the foods we ate got softer and our mouths subsequently changed [1]

#44Very curious why you'd take this approach over something like the Boston Keratoprosthesis ( https://eyewiki.org/Boston_Type_1_Keratoprosthesis ). With a history of cornea rejection, mine has been stable for almost 16 years.
From your link
> Many studies have shown the incidence of repair procedures and worse final vision outcomes were higher in groups with autoimmune conditions (SJS, OCP). The difference in outcomes appears to be related to the degree and cumulative past period of inflammation. Overall most favorable outcomes are achieved in non-cicatrizing conditions, followed by ocular burns and OCP with the worst outcomes in SJS patients.
The patient in the article was a SJS patient

There are some circumstances where a keratoprosthesis won’t work, particularly if the eye has no tear production. OOKP is a good technique in some where they are blind in both eyes from severe ocular surface issues but the retina is still intact. It is very resource intensive and involves a number of subspecialty areas, and so is a last ditch effort for the bilaterally blind.

#46One thing I don't understand is how the surgeon ensures the lens is positioned correctly. We're talking about a rigid lens that can no longer be controlled via muscles, right? Doesn't any misalignment mean you get a fuzzy image at best? And even if you can get a sharp image for some given, fixed distance, you still can't control whether to focus on near things or far things when you look, right??

Imagine if we could put an iphone camera or something like that into the eyeball and somehow wire it up to the brain. That'd be sick.

If you've ever played around with a magnifying glass, they accept a surprising amount of tilt. It's not a clear image, but a blurry image is better than no image.
This surgery is for people who've had their eyes destroyed by chemicals or similar. They don't always have the structure remaining for any finer control.

That's by far the most cyberpunk looking prosthetic I've ever seen. I'm glad it works for you, thanks for sharing!
