Because laser surgery isn't safe, permanent or cheap?
Say what?!
its not safe - you can end up worse then you thought or in the occasional case blind or MUCH worse then you started. Thus it isnt safe yet.
Its not permanent, in many cases years after receiving the surgery you need to get it done again or your vision ends up deteriorating again again the effects of this vary from person to person and how long it lasts varies also.
Its not cheap - considering if you have half decent vision insurance you can get your glasses for like nothing once a year or 50 bucks once a year, vs spending 2-5k on lasik surgery which might last 10 years you tell me which is cheaper.
