Ever hear of Colloidal silver? It is not cheap but is worth the money. I had an eye problem for a few days this last week and thought is was because I had gotten dust in my eye at my work place. Well, last night I was beginning to think it may have been a sty. I decided to use a little bit of colloidal silver (at 10ppm) in a solution of eye wash and rinsed my eye with it. I have had no issues today. It has been perfectly fine.
