The
PuriLens® System
A Breakthrough In Contact Lens Care
Scientific
Research Shows Safety and Effectiveness
- A study conducted to test the disinfecting efficacy of the PuriLens System reported a near 100% removal of microorganisms after using the PuriLens System. A variety of microbes were tested at both three and fifteen minute intervals to measure reduction of debris on contact lens surface. After three minutes in the PuriLens cleaning system, 99.99% of microorganisms were eliminated. Disinfection Efficacy Testing of the PuriLens System, Consumer Product Testing Co., Feb 1999.
- A multi-center study of 84 patients was conducted to evaluate the safety of PuriLens. The findings published in The CLAO Journal suggest that PuriLens may be considered a safe alternative to currently available contact lens cleaning and disinfection methods. Eighty-seven percent of the subjects reported satisfactory results and wished to continue using the PuriLens System over previous methods.

- A double-blind study conducted at the University of Alabama Birmingham School of Optometry using computer imaging demonstrated that lenses cleaned with PuriLens versus leading multipurpose solutions were cleaner by a statistically significant margin.

- In a six month, random assignment crossover study of 80 subjects, PuriLens was compared to a traditional soft contact lens cleaning regimen in three key areas of lens care: cleaning, disinfection and compliance. PuriLens was shown to significantly reduce signs of deposits on contact lenses in 94% of exams. The PuriLens System reduced the number of microorganisms by 99.999%. Additionally, 87% of users reported that lenses were very comfortable after cleaning with PuriLens.

- In a case report published in Contact Lens Spectrum, the PuriLens System was found to alleviate multipurpose nonkeratitis, or lens dryness resulting from a multipurpose contact lens cleaning regimen. PuriLens was recommended for patients as an easy, inexpensive form of chemical-free disinfection of contact lenses.

Surveys Reveal Satisfaction from Physicians and Patients in Canada
- Research was conducted among a sample of the 500 lens specialists who have 3,000 soft contact lens wearers using the PuriLens System. Eighty percent of the contact lens specialists surveyed cited fewer problems with patients who used the PuriLens System. Among the most widely cited merits stated were assured compliance with cleaning methods and ease of use by patients. Survey, Toltzis Communication, Apr 1996.
- A PuriLens research survey showed that, on a scale of 1.0 (unsatisfactory) to 5.0 (very satisfied), patients reported a 4.4 average overall satisfaction with the cleaning system. In addition, nearly half of these PuriLens users stated that ease and convenience of the method were reasons for switching from traditional chemical cleaning. Survey, Toltzis Communication, Inc., Apr 1996.
