I had corrective surgery over 15 years ago now. Had wavefront lasik in one eye and prk in the other, due to various things such as corneal thickness and strong prescription. I was living in the US at the time and found that local to me was one of the top corneal surgeons in the states. I don't remember what I paid, I think it was about $2k per eye but I didn't care at the time. I went with the top surgeon in the field and just dropped the credit card in the machine. I'd been waiting for two decades for the technology to catch up with my prescription of -8.5 and -8.0 but the surgery is nothing short of miraculous.
10 years on, one of my eyes started to change slightly and now, 5 years on from that, my right eye is -1.5D while my left is still 'laser' sharp. Annoying that my right eye dropped as that's my dominant eye for shooting :/ I wear a daily disposable contact lens to bring my right eye up to 20:20 but it's still never quite as sharp as my left eye.
I'm 51 now and also need reading glasses, but was warned at the time that the surgery wouldn't change that.
I would do it again in a heartbeat but I would be very picky about my choice of surgeon. I researched things like complication rates, who they send you to if there's a problem (in the states local to me, that turned out to be the surgeon I chose to have operate on me) and what their backup options are if there's a problem. Cost would be the last thing I looked at.
