I had Lasik done five months ago. Overall, I am quite pleased as I had pretty severe myopia (roughly 950 in both eyes plus astigmatism). I have noticed, however, two things:

1) My dominant eye is just slighly undercorrected, which I understand to be not uncommon in those with severe myopia like me. I am told I could get a touchup, the slightest of its kind. I know the risk of infection is the same as before. But what I haven't been able to find through research are success stats of those who bother to get it done. I'm trying to determine if it's worth it. It is slight but annoying nonetheless since my other eye is perfect. I am aware that my eye won't get any better on its own. Yet the thought of opening up an existing flap is unnerving and I am concerned the healing can't be as good as the first time around when the flap was smooth. I'm told the flap will inevitably be jagged when pried open. The doctor held up a lens in front of the bad eye and that slight prescription definitely made a difference so if it worked, I'd be elated. But I'd like to know, say, of X number of people who had it done, what the failure rate is. And the consequences, e.g., worse vision. If vision is overcorrected, can nothing be done because tissue can't be put back?

2) Floaters. I did some online research and learned that this is unlikely due to Lasik. Yet I swear I have never noticed so many floaters (clear squiggles) before. Even a moving faint grey spot. No flashes of light though (my eye doc checked my retina). Any insight (no pun intended)? I recall only in childhood seeing some floaters and I read that once you have them, they never go away. So did my brain just become more alert to them post-Lasik? Or is my noncontact lens vision somehow more attuned to them?
