I can personally testify to the fact that as a large-pupilled, blue-eyed person, that PLEC in Vancouver with their transPRK SmartSurfACE, has left me with night vision superior to that of wearing glasses and contact lenses, and at a 20/12 visual acuity at my last check-up, and quite likely 20/10 right now. Even at very low light conditions (ie: getting out of the city at night and looking at the stars!).
The problem with laser eye correction for a pilot is that undergoing a procedure, whether it is LASIK or PRK (I prefer PRK for many reasons, especially since airplane air is very dry), is that such will take you out of the cockpit for a while. And that complications could ruin your career. Ask your medical examiner or Transport Canada for actual details, but your license will be suspended/revoked for a month or two at least until you meet the standards.
