1 Results of in vitro study following FDA/ISO stand-alone procedure performed with the addition of organic soil to create a more rigorous test condition. Primary criteria for effective disinfection are defined as a reduction in the number of bacteria by a minimum of 3 logs (99.9%) and a reduction of mold and yeast by a minimum of 1 log (90%) within the recommended disinfection time. Graphs depict mean log reduction measured after manufacturers' recommended disinfecting time (soak only). Biotrue, Clear Care, RevitaLens OcuTec, and OPTI-FREE PureMoist results from separate in vitro study performed following identical test procedures.
