As I said, you need to do a comprehensive lit review not jump on an anti-lasik sight for some dated and out of context quotes! George Waring brought Lasik to this country for example. My ophthalmologist did a Fellowship with him and he is not ant-lasik, nor do most people ever need a repeat procedure years later! Warring would tell you that!
Go on Medline, do a search for any of those "problem areas" and read the whole paper, look at the methodology, etc. They publish RECENT research every month. Drops in contrast sensitivity for example usually return to baseline by 6 months post op. Wouldn't know that from the kind of dated, out of context quotes that just talk about..."there is a drop in contrast sensitivity..." without knowing the time period wherin they are sampling this, but hey, we vote people into office on soundbites. Few people employ critical thinking anymore.
