ABSTRACT:
Multi-purpose solutions for contact lens care provide substantial lens wearer/user comfort and/or acceptability. Such solutions include an aqueous liquid medium; an antimicrobial component, preferably a biguanide polymer present in an amount of less than about 5 ppm; a surfactant component, preferably a poly(oxyethylene)-poly(oxypropylene) block copolymer surfactant, in an effective amount; a phosphate buffer component in an effective amount; a viscosity inducing component, preferably selected from cellulosic derivatives, in an effective amount; and a tonicity component in an effective amount. Such solutions have substantial performance, comfort and acceptability benefits, which, ultimately, lead to ocular health advantages and avoidance of problems caused by contact lens wear.
