Hello

I would really love some feedback on this issue..
I had my Lasik surgery a couple years ago, only had -2.50 and -2.75 to start with and ended up with halos, and as someone here described it as the edges of letters and objects not being very well defined...
A year ago I had an enhancement done on both eyes, one of them got a lot better, all the halos and problems disappeared. but the other one remained unchanging..
I can really feel the difference and never seem to be able to just forget it and let it go

even though I have a 20/10 in both eyes.
should I undergo a second enhancement for the one eye that wasn't fixed with the first enhancement?
I had minor epithelial in-growth with that same one after the first enhancement that was limited and went away by itself...
What is the rule on doing a second enhancement..
