Purpose: We aimed to evaluate the product performance of a novel one-step hydrogen peroxide cleaning and disinfecting solution, PeroxiClear (“Test” solution), when used by habitual Clear Care users to bilaterally clean and disinfect their soft contact lenses, for approximately 2 weeks.
Methods: This was a 2-week, open-label, bilateral eye study designed to include subjects ranging in age from 18 to 55 years, inclusive. All subjects were habitual users of the Clear Care peroxide regimen for cleaning, disinfecting, and storage of their soft contact lenses, for at least 6 months prior to enrolling in the study. Subjects were examined at two study visits: a screening/dispensing visit and a 2-week follow-up visit. The primary end point, patient preference for the Test solution, was evaluated with an online survey administered after 7 days of using the Test cleaning and disinfecting solution. Respondents could answer questions with neutral or nonneutral responses (better or worse). Statistical analyses were conducted to compare differences for nonneutral responses.
Results: Of the 299 eligible subjects enrolled, 297 completed the study, conducted at 21 sites by 21 investigators in the United States. A significantly higher proportion of nonneutral respondents reported the Test solution was better overall (85.9%) than their habitual contact lens solution (14.1%) (P<0.001). The proportion of subjects who preferred the Test solution over their habitual solution was significantly higher for each of the preference questions regarding comfort (85.4% vs 14.6%), moistness (90.0% vs 10.0%), cleanness (91.6% vs 8.4%), and clarity of vision (85.8% vs 14.2%).
Conclusion: After 7 days of using the Test cleaning and disinfecting solution, survey results indicated high levels of patient satisfaction and preference over the habitual solution, particularly in the areas of comfort, moisture, and cleanness.
