An ophthalmic composition comprising a polymeric biguanide composition having less than 18 mol% of terminal amine groups and 55 mol% or greater of terminal guanidine groups as measured by 13C NMR, and 0.005 w/v% to 0.04 w/v% hyaluronic acid. Alternatively, the ophthalmic composition comprises a polymeric biguanide composition comprising less than 18 mol% of terminal amine groups and 40 mol% or greater of terminal cyanoguanidino groups as measured by 13C NMR, and 0.005 w/v% to 0.04 w/v% hyaluronic acid. The compositions can be used for cleaning, disinfecting or packaging a contact lens. |
