Why would they suggest such a thing? Your iris should still work perfectly.
I think the thing about deciding on a distance has a lot to do with age. A lot of oldies find their focal distance goes out and out as they get older. Mine went past infinity. Just. Wearing reading glasses is just part of life and since I do lots of tekkie things like repair watches, I'm swapping them on a regular basis.
The little things that stretch the original lens work opposite to the way many people think. Trying to improve vision by exercise is like pushing a piece of string.
The American surgeon that did my left eye tried very hard to get it perfect for me. They even bought out a magnificent bit of old kit that measured the lens to retina distance. I panicked a bit when it was first uncovered but it settled down okay. Again, I'll mention the original astigmatism remained. That was disappointing but hardly noticeable and no one's fault..
