If anybody else has had this happen (lurkers, anywhere?) I sure hope you'll speak up.
I'm sure I'm not the only LASIK patient with post-operative floater onset who is having a little deja vu here... All our doctors told us it was a coincidence. To this day it's one of the least talked about, least explained "coincidences" that occurred to a whole awful lot of lasik patients. For most of us it was just a nuisance (e.g. swatting at mosquitoes that weren't there) but for some they affected vision so much that they opted for floaters-only vitrectomy. (Talking of risky procedures.)
No one can say authoritatively what are or aren't side effects from IPL (statistically, I mean) when nothing's been published. I'm sorry for what happened to you.
