Keep using the Neosporin. It's just as good as Terramycin, and this is my experience since I've used both, as well as Vetericyn eye gel. Vertericyn eye gel is nearly useless, and the gel is hard to get out of the bottle. It's frustrating and aggravating. By all means buy some if you enjoy being frustrated and aggravated. Saline works just as well and is cheap and easy and effective.
