Boots, the CF still does not allow corrective eye surgery for pilots. There have been many folks flying on the civy side who have had lazik, some with thousands of hours and years of no problems. I suppose the CF is concerned about other issues, reversion of effects, unknown effects at high altitudes, effects on use of night vision goggles, etc... I can't speak for the medical community, I just know that eye surgery for pilots in the CF is not an option at the moment. I don't know if this will change in the future.
To pass medically through the Aircrew Selection Center, an applicant must meet Vision category 1 requirements: uncorrected 20/20 vision or better. Later in a pilots career, their vision can degrade to Cat 2 vis, but only under certain conditions can they stay flying - IIRC, no worse than 20/200 uncorrected, correctable to 20/20 with glasses and no astigmatism...so you will see some pilots wearing glasses. Any worse than 20/200 uncorrected or any astigmatism at all and it's V3 or worse = no go.
There are some other threads on the corrective eye surgery thing, including ideas of enter as a navigator in the hope that lazik might be allowed in the future, but to be honest....I would assume the worst case (CF won't change its mind on lasik) and join the CF only if there are careers that interest you if you were not able to change classification or trade in the future.
Cheers,
