Nope I haven't, was referring to something else, but never mind. And i'm not one to tell you what you should or shouldn't do since i'm the same age as you. Therefore i'll leave that to some of the other more knowledgeable members.
BTW i was advised against getting laser eye surgery by an employee of the RAF. He told me that there's no guaranteeing your eyesight doesn't deteriorate after a certain period of time.
