Abstract
Disclosed herein are ophthalmic solutions and methods of using the solutions which comprise a complex of at least one cationic component and an anionic polymer, wherein the complex can be used as an antimicrobial agent. The solutions described have complexes which can be dissolved in aqueous ophthalmic solutions due to both lower charge load and lower total polymer concentrations than commonly taught. The complexes display different antimicrobial profiles than the non-complexed antimicrobial agents.
