I haven't. but my friend's hubby, Gregg, has, in both eyes. He didn't find the experience pleasant, but now, 18 months on he's glad he had it done because at 32, for the first time in his life he has perfect vision.
at the time he found it a real drag because it made his eyes hurt and he had to wear shades everywhere for ages. they told him in the clinic he would need to wear them for just a few days while in the house, but those few days turned into a couple of weeks or more for him, but like i said, he has perfect vision now, and the pain is all forgotten.
