Our weim had cherry eye surgery back in September. It looked better that same day, and she never had any problems with it. She sometimes wakes up with extra eye goo in it, but that's about it. It never quite settled, and you can see the nictating lid a little bit, but our vet said it looks good. I don't think it looks that good, but he said that it's fixed and that's about as good as anyone could do it. He didn't even do the surgery, we had it done at another clinic because our vet wanted too much money.
I would have the vet look at it again, that doesn't sound right!
