Hello and welcome kneedown!
I had PRK laser on my eyes a few months ago. Like yourself I'd a history of migraine as well as MS, and I also have had bouts of optic neuritis during the last 15 years. This didn't rule me out for PRK and it has been successful. The opthalmologist I went to did not request permission from my neuro - but I'm in Ireland so things probably differ from clinic to clinic. I didn't go to a laser eye clinic, rather to a private opthalmologist, one of the best in Dublin so as to ensure the most thorough analysis of my suitability for the procedure. He did send me for a colour test and a vision-field test prior to the surgery though.
It was successful, I'm glasses-free now, one less thing to think about! I have the occasional day of dry eyes but my eyes were a bit dry anyway. I am a bit light-sensitive but I don't mind that too much and it is very slowly improving.
Hope that helps and let us know how you get on.
