I work for an ophthalmic surgeon and we do these surgeries in the office. You shouldn't have much pain. You will be swollen and bruised for the first 4-5 days. We advise putting ice packs on eyes 20 minutes on and and 20 minutes off while awake the 1st 2 days. Really cuts down on Swelling. Other than that, Leave eyelids alone until sutures come out in 1 week. After that, each day will get better and complete swelling should be gone in a couple weeks. You will be happy you are having this done. We also Rx antibiotic to prevent infection. Good luck and happy healing☺
