Sometimes, swelling can be an adverse reaction to something in the eyedrops. It would be a good idea to get yourself in to see your doc and have him/her take a look at things.
Swelling under the eyes is normal after a cataract surgery. It is caused by the anesthesia and eye drops used during the surgery. You must have a follow up check up with your eye doctor, to make sure that you're not having another vision-threatening eye disease.
I look terrible. Like I've been out all night living it up. Bags and dark circles that were not there before the cat surgery. The eye doc says I looked like this before but couldn't see it because I needed cat surgery. Not true, used to put makeup on w/magnifying mirror. They had taken a close-up picture when I first went in. When we looked at it - no bags or circles. The excuse now is that I wore glasses before and they covered up the bags and circles. I've tried to research to see if eye drops could have caused this and if it is a temporary situation. It's very depressing to look in a mirror.
