Hi flygirl_sa2002,
Try and do a search on laser eye surgery. Here you will find losts of posts about the pro's and con's of this technique.
From my understanding the RAF will not let you train as a pilot if you wear glasses or have corrective surgery.
Please don't hold me to that. I'm sure someone else can give you more details.
I wanted to be in the RAF, but wear glasses. As a result they would not let me train as a pilot. I have decided to go private and start off with a PPL.
Hope that helps you in someway.
