Ophthalmic optics. Contact lens care products. Method to assess contact lens care products with contact lenses in a lens case, challenged with bacterial and fungal organisms. | Status: Confirmed, Current

1 Scope This International Standard specifies an antimicrobial efficacy end point methodology to determine compatibility of contact lens solutions, lens cases and hydrogel lenses for disinfection. This provides a process for evaluating compatibility of solutions used for disinfection with contact lenses and lens cases using an antimicrobial efficacy end point. Specifically, the microbiological effect of the antimicrobial agent(s) while in the presence of the lens cases and/or lenses will be evaluated as described in the soak step of the label instructions. For practical purposes, this does not apply to oxidative systems.
