FWIW, I had cataract surgery two days ago (left eye). My appt started at 9:30 am with tests, tests, and more tests. Wait and then more tests. Consult and then wait. Finally pick out the lens I wanted, and go upstairs to the surgical center and wait. Finally, I had surgery and was returned to my husband for the trip home at about 2:30 pm.
So a total of five hours.
I never took off my mask for a single minute. They even left it on during surgery. All they did was lift it slightly and put an oxygen cannula in my nose.
It was fine. I was fine. Everyone in the building had on a mask, staff, patients, everyone.
I don't mind a well fitting comfortable mask one bit and will wear one probably forever. 🙂
