I had both eyes done, about 11 or 12 years ago, best money I've ever spent.
I went from something like a -6 in one eye & -4 in the other to -0.something in both eyes, spectacular but hoped for result. I was very short-sighted before the op, had good vision after.
My eyes have deteriorated over the years, & I do need glasses now - but I'm not bothering with them as I can still easily get by without them (plus, I don't drive).
Like someone else said, it's very liberating to no longer have to wear glasses - it allowed me to restart taekwon do, not really possible before, I'd had to forgo contacts due to conjunctivitis.
The procedure did sting a bit, & the eyes hurt for a bit after, but that was nothing. I do remember smelling burning during the procedure - smelt like burning insects
I think my eyes have been a lot healthier since the surgery. If I look for them, I can now see the occasional floater, but oth I'm 51 years old. What I don't get anymore are headaches from wearing such heavy glasses & straining to see stuff, I'm no longer continually trying to get glasses to fit or stay in place.
Certainly if your eyes are bad I'd recommend laser surgery, if you're just a tad short-sighted, if it's more a cosmetic thing, I'm not so sure.
