CONTACT LENS DISINFECTION PROCESS, PRESERVATION OF AN OPHTHALMICALLY ACCEPTABLE MEDIUM AND PREPARATION OF DISINFECTANTS FOR CONTACT LENSES BASED ON A QUATERNARY AMMONIUM POLYMER

摘要

Ophthalmic compositions, such as those used to care for contact lenses, methods of preserving such compositions, and methods for disinfecting contact lenses using such compositions are disclosed. The compositions may comprise an ophthalmically acceptable, liquid aqueous medium and, included therein, an effective preserving or disinfecting amount of certain oxygen-containing ionene polymers.
