title: Comparative disinfectant efficacy of two disinfecting solutions against Pseudomonas aeruginosa.
abstract: OBJECTIVE
  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 10(8) 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.
