Abstract
An improved ophthalmic composition comprising an anionic polymeric substance, such as Hyaluronic Acid and/or Carboxymethylcellulose, in combination with any of various cationic monomeric or dimeric antimicrobial agents, such as Cetylpyridinium Chloride and/or Alexidine Dihydrochloride, wherein said compositions provide additional comfort and biocompatibility with lenses without significantly affecting the antimicrobial efficacy of the antimicrobial agent and without therefore requiring a substantially increased concentration of the agent such as that could expose contact lens wearers to increased levels of the disinfecting agent. Solutions according to the present invention may be used for effective multipurpose contact lens disinfection compositions, lens packaging solution compositions, and/or eye drops such as rewetters and tears.
