We evaluated a new integrated contact lens care system that combines fluid turbulence for lens cleaning with ultraviolet (UV) light for solution sterilization. The ultraviolet light system was used to clean and disinfect 42 soft contact lenses (water contents: 38.6%, 43%, 55%, and 70%) and two rigid gas permeable lenses. Test lenses were contaminated with 10s cells/mLof Bacillus pumilus, Aspergillusniger, Pseudomonasaeruginosa, and Acanthamoeba castellanii and subjected to a 15-minute cleaningdisinfection cycle. Bathing solutions and contact lenses were cultured at various time intervals and atthe end of the cycle. All bathing solutionsand all lenses but one were found to be sterile after one cycle. All units effectively disinfected solutions and contact lenses. This device may be an effective alternative to existing contact lens care systems.
