There are videos on youtube - but basically they cut a flap of eyeball, peel it back, laser the underneath and then roll the flap back.
Have you though about contact lenses?
I can understand people not wanting to wear glasses but all the expense, pain and risk do not seem worth it compared to 'night and day' contact lenses.
A lot of people, and I mean a LOT aren't suitable for night and day glasses, the lenses are rated at up to 30 days, but when you get them you're supposed to do the usual few hours first day, increasing over time and optician is supposed to keep a very close eye on you the first few days you wear them overnight and continuously, most people are told they really shouldn't wear them all the time.
I don't get on with them at all well, in as much as I find them very very uncomftable but can wear them for several days at a time. Still have problems with things like swimming and, its pretty much a statistical odd's on probability that in your lifespan of wearing contacts, one will rip, and scratch your eyeball or you'll get an infection when one isn't cleared properly. I've had one scratch from a contact lense, which resulted in inability to wear contacts/glasses for a week, being all but blind, having to wake up hourly to to antibiotic drops, because infections in the eye are very serious.
Likewise, playing sport, mud in the eye, dust when riding a bike, wearing glasses also presents problems in all the same ways.
This is the thing that swayed me(can't afford it yet though), the risk of the surgery is low, so far no ones gone blind and the massive majority get significantly improved vision, even if it means less glasses use, or cheaper glasses and thinner contacts have to be used its a plus, most people don't need either after. The problem is, glasses and contacts DO carry risks, your risk of eye infection over someone who doesn't wear contacts is increased massively, the cost is pretty expensive if you only really get on with dailies(though you can wear them longer, but again, thinner material, more likely to break which can cause problems).
I'd be likely from my age now, to spend just as much on surgery as I would on glasses and contacts over the next 10 years really, if the surgery works and I get 20 years before the "old age" vision issues start, then i've saved a bunch and avoided lots of problems.
