I had LASIK done 12 years ago. Other than marriage and family, it was the best thing I ever had done. I was one of those people who was extremely nearsighted. If I woke up during the night I would put on glasses to go to the restroom. If I had no glasses on and I was looking at someone 20 feet away and didn't already know who it was I wouldn't recognize them. Swimming was always difficult. Without contacts or glasses I couldn't see. I tried prescription goggles but they gave me a headache. I got tired of feeling my activities were limited.
I am extremely risk averse to deciding to do LASIK was a big issue for me. I did a huge amount of research on LASIK. When I ultimately did it I put out an online diary of my experience and had a web site devoted to LASIK and the risks and how to decide and who to limit risk. This was before Google when the Yahoo directory was the main way to search. For a long time when people searched on LASIK my webpage was in the first few listings. I got tons of traffic and got emails from lots of people having LASIK with their results good and bad. After a few years I really had nothing more to say since my vision was stable.
Anyway a few comments.
1. Someone said that results from LASIK don't last. This is not exactly accurate. Results from LASIK do last. However, LASIK does not prevent future changes in vision. If someone's vision is not stable and is continuing to deterioriate LASIK won't stop future deterioration. In my case, my vision after LASIK was about 20/25 and over a period of a few years did change to 20/20.
2. Having to wear reading glasses (LASIK doesn't prevent that) is way less onerous than being nearsighted.
3. I did a ton of research on surgeons. When I was looking in my area there were clinics that advertised low cost on the radio, etc. I didn't go to any of them. I found that one of the premier LASIK surgeons in the world lived in my area. More to the point, he had done LASIK on my other physicians, including an astounding number of opthamalogists. I asked physicians that I knew who to go to and they all recommended him. He didn't advertise extensively and was more expensive. I went to him anyway.
4. I chose to do each eye on separate days. Many people thought that was ridiculous of me. I am still glad I did it. I had one eye done, made sure vision was stable in it, and then had the second eye done.
5. I did have astigmatism, although not terribly severe. I was still able to do LASIK. Someone with astigmatism needs to be evaluated to determine
whether LASIK is appropriate.
6. People with negative experiences are way more vocal than those who had a great experience. I kept my web page up for a few years after having surgery but eventually took it down because I had nothing more to say and I wasn't researching LASIK any more. If I had had a bad experience it would probably still be up....
6. To the original poster -- each situation is different. I suggest that you research and find a good surgeon and get evaluated.
