i was absolutely TERRIFIED of getting lasik! but my husband really wanted me to do it and i really was getting sick of contacts and glasses.... plus, close to 10 years ago, my best friend had lasik done and had 20/20 vision as a result and she has been telling me ever since then to get it done. and when she had it done, the technology was so different and not quite as advanced as it is today! so i always told her i'd give her at least 5 years to go blind before i'd even consider it.... and since she still had 20/20 vision, back in november when i started really thinking about it, i told my husband to research it all and let me know what he could find. well, he only found POSITIVE things about it, so i knew he didn't search it right, and i looked it up myself, and i found all the negative sites you mentioned.... yeah. scared me to death!
so i wrote down all the negative things i read, and brought them with me when i went in for my consult. they answered all my questions, showed me the actual stats for the doctor who would be doing the surgery - like how many patients needed enhancements, who ended up with less than 20/20 but couldn't get an enhancement, and how many people ended up horribly blinded from lasik.... the numbers for the first two were suprisingly low, like maybe one or two for each, and the third one was zero. nobody was blinded or had worse vision from having lasik done from this doctor. that's not to say it doesn't happen though....
i think if you read those anti-lasik sites carefully, a lot of them are written by people who didn't research their doctor very well.... a couple of them i know, had lasik done in one of those portable trailers that go from city to city performing cheap lasik! that's where the rule "you get what you pay for" really comes in to play!
long story short (or less long, anyway), lasik is a scary thing. you are messing with your eyesight, which is pretty crucial for leading a normal life (yeah, i'm sure that's not very PC to say, and a blind person would probably be furious if they read this.... oh yeah.... that's kind of my point, isn't it?). but if did your research and you have a good doctor, you should be just fine.
just don't buy into all the next day 20/20 hype, because it generally takes 2-3 months before your vision really stablizes (it can take up to 6 months!) and your eyes fully heal. if you go back and look at my other earlier posts here on this board, you can read about my lasik recovery and all the FUN i had with it (that was sarcasm, BTW!). but my vision was -5.25 before lasik, and now it's 20/12.5 in both eyes, so i'm happy with it, i recommend it to everyone i know, and i'd definitely do it all again!
