I watched a dog being neutered on TV - and they did put an ointment in his eyes for that procedure. They said that dogs (and people) don't blink when they are under anethesia and their eyes can become dry and sore because of this.
You might run a search on "anesthesia" here on YT because this topic has been brought up often. And, I know that different types of anesthesia have been mentioned often.
