One 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??

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.

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.
