I have not had it done, but we did our research and got several referrals for several DR's for my wife. This is a personal decision but I will tell you I have never seen her more happy since she decided to do it. She hated glasses and contacts and always complained about them, she wore them for 20 plus years. I think something that should be considered in this is the fact that you will eventually need readers, at least she does and the DR said thats an age thing.
So my plan was to do this for my Daughter after she graduated college, but she entered a drawing for free surgery with one of the highest rated Eye DR's in her area and she won. She loves it and was in the same boat as my wife, hated glasses and contacts and was something she really wanted. I got lucky on this one, but it made me a nervous wreck, but we checked his references and checked with my Brother-in-Law and she proceeded.
The moral of the story, do your due diligence and do it again before proceeding. I personally would do it if I could get rid of my reading glasses because I can only go so big with a computer monitor before I have to put them on. I also hate that I can't read my phone without glasses so I have to purchase sunglasses with readers built in.
If I could get rid of them then I would do it, but thats because I have faith in the DR.
I agree with MoabMan, its your eyes and they are not replaceable.
