Purpose: We compared the disinfecting efficacy of Pure Eyes Disinfectant and Opti-Free Rinsing, Disinfecting and Storage Solution, without recommended daily cleaning steps, against Pseudomonas aeruginosa. Methods: Vifilcon A soft contact lenses were inoculated with the challenge organism, P. aeruginosa ATCC 15442, at a concentration of 1 x 108 colony forming units (CFU/mL) and disinfected with each solution for four and six hours, respectively. Results: Pure Eyes eradicated P. aeruginosa after both four and six hour soak times. With all lots of Opti-Free, colony forming units were too numerous to count (>200) for both soak times. Conclusions: We concluded that, because Pure Eyes disinfecting solutions can eradicate P. aeruginosa without the benefit of a daily cleaning step, this disinfecting process may offer protective benefits to noncompliant contact lens wearers.
