MULTIPURPOSE LENS CARE SOLUTIONS FOR DISINFECTING CLEANING AND RINSING CONTACT LENSES

摘要

The present invention provides a lens care composition having a persistentlipid removal efficacy characterized by that the amount of lipids adsorbed bya silicone hydrogel lens after about 10 cycles of soiling with a lipid soilingsolution and subsequent cleaning with a lens care solution of the inventionunder no-rubbing conditions is about 70% or less of that after about 10 cyclesof soiling with the lipid soiling solution and subsequent cleaning with anaqueous phosphate buffer under no-rubbing conditions. The lens carecomposition comprises at least one surfactant, a polyvinylpyrrolidone (PVP),xylitol, a buffering agent, wherein in combination with polyvinylpyrrolidone(PVP) and xylitol, the surfactant provides the persistent lipid removalefficacy.
