Pictures would be helpful. Are you seeing the third eyelid (nictitating membrane?) She might have suffered a tear in the injury. Do you think they were picking on her when she was injured? Moisten watery chicken feed and tuna, and even a small amount of canned cat food are other things that might interest her.
I think that I would use some saline in the warm wet compresses to the eye 2-3 times a day with a clean washcloth. Hold her while you apply it. Then coat with the antibiotic ointment twice a day. Neosporin, triple antibiotic, bacitracin, or Terramycin available from feed stores are all okay. You can make homemade saline by adding 2 tsp of salt to 32 ounces/1 quart of water, and boil it for a few minutes, then let it cool.
