"Everyone you know" to have had the surgery probably isn't enough data to draw conclusions.
Google "long term laser eye surgery effects" and you'll stumble across the potential pitfalls of the operation.
Remember I'm someone who also suffers from short-sightedness (-3.75, -4), so Laser Eye Surgery is something I've considered for myself. I'd like it to be a safe and reliable operation with predictable effects.
But from reading sites like this (and not _only_ this one):

I've come to the conclusion that it's a gamble. Maybe there are good odds of success, but the whole thing is unpredictable.
