There is a method to my madness, so bear with me.
Do you have a food scale that you can weigh her on? If not, can you get one? Now that you have a baseline weight of 1.1 kg, and since you are trying to figure out if something else is ailing her, or if the eye is painful enough that she doesn't want to eat, it would be best to start weighing her once a day. If her weight drops below 1050 grams then I think you need to think about having the vet look at her again.
