Abstract:
A multi-purpose aqueous liquid contact lens care composition consisting of:a non-oxidative antimicrobial component in an amount of less than 5 ppm, said amount of non-oxidative antimicrobial being effective to disinfect a contact lens contacted with said composition, a surfactant component in an amount from about 0.005% to about 0.8% (w/v), said amount of surfactant being effective in removing deposit material from a contact lens contacted in said composition, and hydroxypropylmethyl cellulose as a viscosity inducing component in an amount from about 0.05% to 0.5% (w/v), said amount of hydroxypropylmethyl cellulose being effective to increase the viscosity of said composition and to enhance the effectiveness of said composition in passively removing deposit material from the contact lens during said contacting, said composition having a viscosity in a range of about 1.5 cps to about 30 cps.
