I was operated in November 2000.
At first I had decided on Lazik, but about a week before doing the first eye, the surgeon called me and said that during a recent conference in the US he had learned that PRK is better suited in the long term, despite being older.
He was the specialist, so I went along with his proposition (I suppose his advice was for real, since Lazik is more expensive than PRK).
I had my right eye done on November, 15th, I stayed ten minutes in the operating room (which actually looks like a dentist's cabinet), and then was free to go home bandaged, with advice on taking up to 6 antipain tablets a day ("you will need them").
The pain was bearable with 4 tablets a day for two days, then it suddenly disappeared.
The bandage went away three days after the operation.
The second eye was done exactly one week after the first: the pain was a little longer, but this was due to cicatrization problems, which forced me to go on cortisone drops for a few months.
A friend of mine, who was operated with Lazik six weeks after me had less problems in the beginning, but she's now lost part of what she had gained and will probably be forced to wear glasses while driving at night.
As for diving: the surgeon told me I should wait until after Christmas for normal pool sessions, but a full four months before going out into open water, I honestly don't know whether this was due to my particular problems or if it's usual practice.
