Method of cleaning contact lenses using carbon dioxide and carbonic acid

摘要

Methods for cleaning soiled contact lenses are disclosed. The methods involve contacting the soiled lens with a cleaning composition comprising carbon dioxide and carbonic acid as cleansing agents. The cleaning compositions do not require abrasive agents such as polymeric beads, nor ocularly irritating agents such as enzymes or surfactants in order to effectively clean proteinaceous and nonproteinaceous deposits from the surface of contact lenses.
