Welcome to NT
We do care and want you to feel at home here.
No questions are too silly.
I did have surgery on my eyes when I was younger. I was amazed that there was little to no pain about the eyes after surgery. The IV was the most discomfort I had. Yours may be totally different, I don't know.
There are always risks with any surgery. I do know some are unfortunate and are going to fall into the negative category, (you're usually given a pecentage of succes ratio - and then define "success" ... and at what costs? or secondary complications

) but sometimes surgery is the only way to correct something and we just have to let it happen and have some trust in our surgeon and hope and pray for the best outcome possible. I know you'll do your part.
It's never good to need surgery. Hope all goes well when it finally comes your turn.
