I want to do whats best for my dog but am not sure I am making the right decision?

I have a 7yr old american eskimo with glaucoma who in just 3 hours from now will be having both eyes removed. She is already blind and is a pain factor now.Am not completely sure how long she has been blind for we just started noticing she would hit into things every once in a while not long before we were told we only had the two options at this point. Put her to sleep or remove both eyes. I love my pup very much and almost feel the only reason I have opted to have the eyes removed is because I dont have the heart to put her down.Then I cant help but feel like it will be too hard to look at her everyday with no eyes and I will just want to cry each time I look at her.I keep telling myself this is about her and whats best for her but how do I feel comfortable with my decision of having both eyes removed in knowing it was the right choice.
