I have. It's worked out great for me.
You might've noticed that many of the older pictures that have been posted of me across the web have me in glasses, and new avatars I post never have them anymore.
I had my surgery done shortly before the summer of 2007, before I took a trip to Europe. I had a grade of 500/500 making it difficult for me to read even large print or street signs. It made no sense for me to go on an extended trip and risk losing my glasses... and while I could easily get a new pair made anywhere, I had a budget of 30 euros a day... meaning getting it made in a foreign country with a higher standard of living would put me into dumpster diving.
As for the experience, it's a painless affair and what you 'see' as its all being done is like watching a few special effects sequences from Sunshine or Blindness.
