I once requested they not do the dye thing on me, it makes me really really sick.
So they sent me, with eyes already dilated, down to some lab where they took pictures and all I did was stare at something that looked like purple fireworks. It was pretty cool.
The 12 lasers sounds way better than the darn 400 and 450 I had at one time (I never want that again.)
I hope everything stays calm for you.
My 1200 laser beam eye has permanent things floating in my field of vision, all the time, but I can still read and all that.
