Summary:Ophthalmic compositions that comprise 0.1 ppm to 10 ppm of a cationic antimicrobial component selected from the group consisting of biguanides, polymeric biguanides, quaternium ammonium compounds and any one mixture thereof; 0.005 wt.% to 0.15 wt.% of hyaluronic acid; and 0.01 wt.% to 1.0 wt.% of an amphoteric surfactant of general formula I wherein R 1 is R or -(CH 2 ) n -NHC(O)R, wherein R is a C 8 -C 16 alkyl optionally substituted with hydroxyl and n is 2, 3 or 4; R 2 and R 3 are each independently selected from methyl, ethyl, propyl or iso-propyl; and R 4 is a C 2 -C 8 alkylene optionally substituted with hydroxyl. The invention is also direct to the use of the ophthalmic compositions to clean and disinfect contact lenses, and in particular, soft, silicone hydrogel contact lenses.
