TSC usually has Terramycin eye ointment available, around $15 for the little tube which goes a long way. They also have NFZ Puffer powder treats eye and earinfections. The cheap, easily available route is regular (no painrelief) OTC triple antibiotic crème. Yes the one for humans. Does not burn, clears stuff up in a day, have used it myself already. Would probably give antibiotics too.
