Had it done a year ago. I had really bad vision with astigmatism, don't remember the exact numbers, but they told me my right eye would never be 20/20. I went with the Lasik / WaveFront / Intralase, figured these are my eyes I might as well not take any chances (I'm in California, imagine an earthquake during the procedure). Cost me about $4500. From research to procedure it took me about a year to finally decide to do it.
Took about 15 minutes for the whole procedure and my results were awesome. A few minor side effects: After the surgery on the way home my eyes began to burn a bit, like when you get hot sauce in your eye, but not unbearable. Only lasted for about 30 minutes then went away. Also for the first few months my eyes would take a little while to adjust to night time. At first I would see larger halos in the street lights. After a few minutes in the dark halos would get smaller. After 4 to 6 months I didn't have any issues adjusting to night time.
I'm very happy I had it done, it's really worth it. Oh and even though my right eye will never get to 20/20 my vision is still excellent. Definitely life changing.
