Yup, it's usually done within a few hours. See your optometrist and he'll probably refer you to some specialists to take a few retina tests, and thensome, then if all is healthy with your eyes, you're good to go.
I have to admit though, the process is kinda disturbing, but if you can hype yourself up and go through with it, it's worth it.
You can check on youtube people that have had their 'surgery' taped. Unless it was taken off, but I don't think it was. lol
