They usually wait 4 weeks (sometimes even 6) before trying to prescribe correction after
surgery to wait for vision to stabilize, and
I know mine improved a bit before
my 4 week postop. I think I'd read they wait perhaps 3 months before thinking about laser enhancement.
re: the halos. I'd mentioned that I see them, but they don't bother me. My night vision is perhaps better than before I had cataracts, but at the least comparable.
