Please see a Veterinarian ASAP. A kitten with an eye infection can have other things going on. Please do not ever give she/he any medication unless you talk to a Veterinarian.
I had a cat with an eye infection once. I treated it with Bacitracin ointment and it seemed to go away. yet the cat died a week or so later. I think the infection went further into his head. I was so sad I did not take it to the vet. Please have it checked by a doctor.
I have just done the same thing. I called the Vet and picked up antibiotic eye drops. You put them on twice a day. Very simple to heal.
If you think that will work, I would use it. But I would definitely take it to the vet ASAP. You don't want the poor thing to suffer. Also, coming from a feral cat, I would recommend getting it checked out anyways.
