I tried these drops after around 5 months and things just were not getting any better, for a short while (30 mins) I thought that it was brilliant, I could see properly at night time, but after this 30 mins I suffered from blistering headaches, it's common with any kind of drops that alter pupil size apparently, I even tried pilacarpine (sp?) drops just over a years ago and these were even worse, they almost blinded me for 2 hours while they started working, it was horrible and left me unable to see anything while they were working.
I would steer clear of drops like these, long term use is not advised and really when you think about it glaucoma meds shouldn't be the answer to botched lasik.
