Hi there! I had cataract surgery done on both eyes and I had similar problems on the first eye that was done. The migraine-like pain disappeared after the doctor changed the steroid drops brand. It is two months now since my surgery and I'm down to once a day drop, however, I'm now experiencing prickly pain behind the lower eyelid that gets worse as the day goes.
I'm wondering if your problem ever got resolved.
Please get a second opinion.
Dr. O.
