METHOD FOR CLEANING LIPID DEPOSITS ON SILICONE HYDROGEL CONTACT LENSES

摘要

This invention is directed to a method of treating a silicone hydrogel lens to cleaning lipid deposits thereon. The method comprises administering to the contact lens a solution comprising a first straight chain polyether surfactant. The first straight chain polyether surfactant has an HLB value that is a minimum of about 18. The second straight chain polyether surfactant has an HLB value that is a minimum of about 12 and a maximum of about 18. The second surfactant is present in an amount effective to improve the ability to remove lipids from a silicone hydrogel lens.
