Comparative disinfectant efficacy of Purilens versus ReNu

1 May 2000


The disinfectant efficacy of Purilens and ReNu Multiplus Multi-purpose solution was compared against Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans. About 10,000 colony forming units (cfu/ml) of each challenge organism were added to the disinfecting solution. At the end of the disinfecting time, 15 minutes for Purilens and 4 hours for ReNu, the number of remaining microorganisms was determined. There was at least a 95% reduction of the initial number of challenge organisms for both systems. They are equally efficient in contact lens disinfecting. The advantage of Purilens is that it is more convenient due to the short period of disinfection of 15 minutes.
