What's amazing to me is that these patients can see. They can't focus their cornea, because that would require muscle response. It's not even clear that they can blink so they would require eye drops to keep their eyes open.
- taneq 10y agoNitpick: The cornea is a fixed focal length, and it's a separate lens behind the cornea which flexes to 'accommodate' or focus the eye.
- pbhjpbhj 10y agoWouldn't that mean the lens has a fixed focal length, so they'd only be able to see clearly objects at a particular distance?
- Dylan16807 10y agoBy the time you're 50, you can only focus your eyes by about 1 diopter anyway. Go try some 1 diopter reading glasses on; it's not a big difference. An uncontrolled eye ends up being quite mildly farsighted.
