Efficacy Of Multi-Purpose "No Rub" Contact Lens Solution Disinfectants.

Background: There are many soft contact lens solutions on the market today, each
product claiming to be the most effective at disinfecting. This research study compares
the efficacy of the following multi-purpose "no rub" soft contact lens solutions and their
respective disinfectants: Solo Care Plus, Opti-Free Express, Renu Multiplus and Clear
Care. Methods: The solutions were tested against Pseudomonas aeruginosa, Staphylococcus epidermis, and Candida albicans. Each organism was grown on several agar plates with paper discs in the center that were saturated with the previously mentioned multi-purpose solutions. The zones of inhibition created by the paper discs were measured, thus allowing a comparison between the solutions under study. Results: The Clear Care solution showed the greatest disinfectant capability compared to the rest. All solutions showed some disinfectant properties towards Pseudomonas aeruginosa. However, Opti-Free, Renu, and Solo Care Plus did not show any disinfectant capabilities towards Staphylococcus epidermis and Candida albicans.
