First off, that last poll item should really be broken out separately, "not needing" (and/or "not being a good candidate for") and "not wanting" it are entirely different things.
She is however, very nervous about risking her eye sight for a convenience. I've tried to research the failure rate
I've never paid enough attention to even know if it can correct significant astigmatism (which I have as well as being nearsighted) but in any event, as far as I'm personally concerned, the only relevant fact is that the irreversible complications rates is < literal 0. (I'm not suggesting someone would have to be nuts to want it, but I also don't think it's paranoid to not even consider it for ordinary vision correction - everyone has different tolerance levels for different health risks.)
I guess if I'd ever wanted to be a commercial/military pilot and Lasik-corrected vision is acceptable in those fields, I might've considered it, but no other reason would ever get me to take
any immediate/acute risk with the eyesight I have (which isn't really functional in the modern world without correction but very far from walking-into-walls-or-stumbling-into-ditches bad.) Except for one
very unpleasant day after they fell off (onto the tracks, between stations) while I walked between subway cars when I didn't have a spare pair lying around, I've worn my glasses from the minute my feet hit the floor in the morning until I get into bed at night since I was 8 years old. Apart from the slight annoyance of having to keep track of them when I go swimming at beaches or in lakes, the only time they ever remotely even annoy me is when I caught get in heavy rain without an umbrella or hood and on the rare occasions when that happens, I just take them off and deal with not being able to see people's faces clearly or read street signs for a little while...
I think that people who as adults were prescribed glasses or contracts are most keen to undergo lasik. If you get glasses at age 3 or so like me, you don't even notice you have them.
I can still remember the woman testing my vision at school (45 years ago) asking if the idea of having to wear them "bothered" me, and really pressing the issue (as though I were refusing to acknowledge my "grief") despite my looking at her like she was insane and pointing out - repeatedly - that it wasn't an issue for for anyone else in my family, so I couldn't imagine why would it bother
me? No doubt I'd asked them about it casually at one point or another, but my parents never even considered it serious/important enough to
"discuss" it with me, but on some level I'd been assuming I'd end up needing them eventually and, as I pointed out (to that rather odd woman's surprise, again), I thought it was bizarre that anyone would intentionally live with with poor vision just to avoid wearing them..
