I heard about a year ago that the requirements under JAR were going to loosen up in the nearest future... I'm not saying that it is, just that I heard that it probably would. Have you talked to the CAA about this? Have you asked if they know anything about this changing soon? I would try that before you decide to do the lasik since it is a risk. Also I would recommend that you gather as much information on the LASIK as you can before going down that road. I was considering this choice about two years ago and bought a book: In Search of 20/20: Everything You Need to Know About Laser Eye Surgery. It both answered a lot of questions and gave good advice. For me the risk was to big since I already held a class 1 medical.
