Got lasik three months ago.
Having read up on a lot of problems with lasik a long time ago, I decided to get one eye done at a time, and to do my worst eye first. That way, if I completely messed up my eye, I'd still have one decent eye. If it worked, I would get them both done.
I can't remember what my vision was like--I'll update this if I find the exact numbers--but I believe I had -2.5 in my left and around -2 in my right. I also have a VERY strong eye reaction, meaning that I can't touch my eye, or let others touch my eye. This caused one lasik surgeon to say he was apprehensive about operating on me and led me to believe I would be unable to get lasik. I tried another doctor who was completely unconcerned about my eye reaction, so I went with him. When the time came to measure my eye pressure (where they must touch your eye), it took a few minutes and some Valium, but it worked.
The GOOD: My vision in my left eye is almost 20/20. I can go without glasses during the day, if I want. I bought a pair of sunglasses for the first time in my life.
The BAD: My night vision has small halos. If it's dark, and there is a bright light (especially white light), there will be a little glow around the light. It's worse when I'm tired or my eyes are dry. I still wear glasses most of the time because having binocular 20/20 vision is better than "looking good."
At first the halos prevented me from getting my other eye done, since I was worried about driving around at night with both eyes like this. However, I decided that I could probably drive at safely night with some slight halos. Then I realized that watching TV or movies in a dark room will make bright spots on the screen pretty blurry. This is most noticeable with subtitles. I am an avid movie watcher and have decided I'd rather be able to see movies with perfect visual accuracy (at least in one eye, with glasses on) than to not have to wear glasses.
Overall, I'm very happy I had it done. Now I don't have to wear glasses during the day. I only really have to wear them when driving at night or watching a movie in a dark room, just like before. Perhaps my left (lasik) eye will improve and I will get the other one done. The doctor said the halos would be gone after a month. They aren't, but the halos have lessened since those first few weeks.
Everyone told me to get both eyes done in one session, but I don't see the point. It costs the same either way and the operation is not such a horrible experience that having it done twice would be an unfathomable nightmare. It was pretty pleasant, aside from some light pain and five minutes of the doctor's assistant trying to measure my eye pressure. I think everyone should get one eye done at a time.
