Just some more reassurance-- my mother had this surgery, and everything went perfectly for her. She never needed glasses in her life until she needed reading glasses in her 60s (! I needed then in my late 40s), and however the surgery corrected her vision, she needed glasses for distance vision afterwards, because she wore them for driving, but she did not wear them around the house. She had the surgery around age 69-70 for one eye, then needed the other one done a few years later.
She kept separate distance glasses and reading glasses; never had progressives or bifocals made. Her reading glasses were never prescription; she bought them at the Dollar store, or some place like that, for just a few bucks, and she still did that, even after the surgery.
So basically, even after the surgery, she could see better than I do. Our family has an odd progressive myopia that often results in people not needing glasses as children, but needing them as older teens, or in their early 20s, and the myopia just progresses. Of all my cousins on that side of the family, only one does not wear glasses, and all of us, plus my brother, started wearing them between ages 16-22. It was 18 for me. College did it. Couldn’t see the boards in my lecture halls. My mother’s siblings have it, but she didn’t.
Having especially good vision to begin with might have helped her to have a very good outcome, but she also is the sort of person who is obsessive about following doctor’s orders to a T. So anything you are told to do-- drops, darkened rooms, eye patches, dietary restrictions, FOLLOW THEM. I’m sure my mother did.
And good luck!
