Two of my buddies had it done. One did it here local and the other did it up in toronto. The one who got it local has trouble seeing at night still after 5 years sence it was done but that has been the only side affect. Other guy who got it done in toronto had trouble seeing at night for the first few months but cleared up after his eyes healed. Hes going on 4 years and still has 20/20.Toronto was more expensive. I would deffenitly say its worth it sence both of my buddies are happy. Just do your research.
