The best candidate for such a medication is povidone-iodine ophthalmic solution. It has already been proven the best agent to sterilize the ocular surface before and after eye surgery and to prevent conjunctivitis in newborn babies. It was also shown an effective treatment against bacterial conjunctivitis in children. Povidone-iodine ophthalmic solution can be prepared in a local hospital or clinic by mixing the powder with an ophthalmic saline solution bringing the cost of a 10-ml bottle to less than US $0.10. By contrast, in the Philippines, a 10 ml. bottle of Neosporin ophthalmic solution cost about $4.00 and it may take a few bottles to cure a bacterial corneal ulcer. For far less than a U.S. dollar, a corneal ulcer could be fully cured. Povidone-iodine has the widest antimicrobial spectrum of any known topical medication. It has been shown to be effective against all bacteria, fungi, and viruses. No true resistance to povidone-iodine has ever been demonstrated. Allergic reactions are rare. Thus, if any medication could serve the purpose for this study, it would be povidone-iodine.
