CLINICAL STUDIES A. AEROTAB Disinfecting Tablet A 6 month clinical trial of 334 subjects (276 test, 58 control) compared the safety and efficacy of the Sauflon AEROTAB Disinfecting Tablet when used with commercially available saline, daily cleaners and wetting solutions to that of a commercial peroxide disinfecting system. There were no adverse reactions with the Sauflon AEROTAB Disinfecting System, and there were no positive slit lamp findings at 90% of the eye examinations, compared to 67% with no findings with peroxide. No symptoms were reported at 81% of visits, compared to 85% in the peroxide controls, a difference considered not significantly different. The most common symptoms were lens awareness and discomfort in both test and control groups. Appropriate visual acuity (within 2 Snellen lines of original best corrected acuity) was obtained by 95% of the test eyes and all of the control eyes. Wear time was not affected by the care regimen. Evaluation of lens cleanliness showed 93% of test lenses and 94% of control lenses were clinically clean at scheduled visits. There were no significant gender differences in the findings. All clinical information concerning the AEROSOLV Unpreserved Buffered Saline Solution is contained in P850074 and its supplements. {3}------------------------------------------------ ## DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/3/Picture/1 description: The image shows the logo for the Department of Health & Human Services - USA.
