I think she needs an oral antibiotic for a few days. You should add Duramycin-10 or a similar broad spectrum antibiotic powder into her drinking water, to fight the infection internally. Adding neosporin cream directly to the eye can help, but it's doesn't seem to be enough on it's own.
I have a rabbit with one eye, who suffered a similar injury as a kit (it's mother scratched its eye while cleaning it). The subsequent infection made it necessary to surgically remove the eye. He lives just fine and happy as a pet with only one eye, and is a great breeder buck, btw.
If you can't get the infection cleared up, it could become life threatening... so you might want to consider removing the eye, if necessary. Good luck!
