You can only get a tube of antibiotic ointment or drops from a vet, unless younget the Terramycin Eye Ointment for sale at feed stores ($15) where it might be locked up. I just spent $30 on a tube of Neosporin ointment for my bloodhound who suffered a corneal abrasion. Ideally, ophthalmic drops or ointment is best, since it is sterile and for the eyes. In an emergency, I have used a brand new tube of plain Neosporin or Triple Antibiotic Ointment for a polish hen who had a severe peck wound to the eye on a Saturday afternoon. A tube of the generic is a couple of dollars, or a dollar at Dollar Tree. You might be risking infection by using the topical Neosporin, but it is up to you. We have had this discussion for many years on BYC.
