If this is distichiasis, the vet is right, it would need surgery. It is extra lashes that grow along the "rim" of the eye(extra lashes) that irritate the eye and could cause ulcers.
Plucking does not work, because they grow back. Maybe you could look closely at her eye with a magnifying glass and you could see those lashes. Did the Dr. show them to you? I have heard that it is heriditary condition-if it is the diagnoses. Sometimes they are little soft lashes, and sometimes thicker ones. The skin is not turned in, like entropian-just lashes. If that is the problem-you know how much it bothers, when something is in your eye! If it doesn't clear up, definitely get a second opinion. You don't want her to get an eye ulcer.
to EBN. Someone else may come by with better info. Hope your baby will be okay.
