I had "custom wavefront lasik" a couple of years ago. It cost 1300/eye.
I am extremely pleased with the result. I went from horrendous vision, being severely far-sighted and having an extreme astigmatism. Now I have 20/15 vision (20/10 left 20/20 right) and have experienced NO problems from the lasik. I would do it again in a heart beat, and consider it some of the best money ever spent.
I have worn glasses since I was three years old, and now I can actually read and use a computer without glasses. Yes, as you get older, you are likely to form near0sightedness, this is a standard part of aging.
You usually can have lasik done again. I have thin cornea's, and was told I could only have it 1 or 2 more times, if needed. It has not been needed.
the custom waveform lasik supposedly does a better job of correcting your vision, but they could just say that to charge more. Do research, and get recommendations from happy lasik customers. I found a doctor who had done 20k surgeries.
