I've talked with my eye doc several times about Lasik, but just haven't gotten the gumption to get it done yet.
She suggested waiting for a 'quiet period', meaning a period where there are no significant vision changes. She said our vision changes throughout our life, so getting it done at a more stable period may mean no changes needed for awhile.
I asked, "So... if it changes throughout our life, why get it done at all? Does it mean I'll just have to get glasses again later???" I've had glasses/contact lenses since I was 7yo, and I've always hated it!
She said:
A. Any later vision changes will be minor in comparison to this dramatic change from the surgery. (My vision is pretty poor.)
B. Minor changes do not mean I will need glasses, and if it's bad enough that correction is needed, I can get a "touch up". For some reason I was thinking once you had the surgery, that was it, you couldn't do it again.
I'm old enough to be on the verge of needing bifocals within the next several years, so that's another reason I've put it off. What's worse, wearing glasses all the time, or being unable to find reading glasses when I need them? I still haven't decided.
ETA: Would you mind reporting your experience when you get back? I'm just curious how you like it. Everyone I've heard of really likes it, though I've heard of bad experiences, too.
