Purpose: The objective of the study reported here was to obtain information on acceptance and satisfaction with OPTI-FREE® PureMoist® Multi-Purpose Disinfecting Solution (MPDS) from contact lens wearers globally.
Methods: Eligible contact lens wearers provided baseline demographic and lens-wear-regimen information, and advised their ocular dryness/discomfort level and current lens-wear experience. Volunteers received OPTI-FREE PureMoist MPDS and a survey consisting of ten statements about the trial solution. Volunteers were instructed to use the solution daily and to complete the survey after 2 weeks of use. Descriptive statistical analysis was conducted on data from the entire group, from the subset of respondents reporting ocular dryness and/or discomfort at trial initiation (symptomatic subgroup), and from each geographic region.
Results: Volunteers from nine countries returned 10,610 surveys, in which 50% of respondents classified themselves as having ocular dryness/discomfort. Lens comfort and visual performance responses from the total population and the symptomatic subgroup were significantly more positive after 2 weeks of OPTI-FREE PureMoist use than at baseline, irrespective of the habitual lens-care solution. In the USA, Southeast Asia, and Europe, 14% to 20% more respondents reported that their contact lenses provided all-day comfort after 2 weeks of OPTI-FREE PureMoist use compared with baseline (P<0.0001). Australia reported 31% more patients with all-day comfort after OPTI-FREE PureMoist use (P<0.0001). Approximately four out of five respondents from both populations reported their intent to continue using OPTI-FREE PureMoist. Globally, 39% of all respondents and 58% of symptomatic respondents experienced reduced end-of-day dryness with their contact lenses after use of OPTI-FREE PureMoist (P<0.0001).
Conclusion: Results from this large survey indicate that respondents globally viewed OPTI-FREE PureMoist MPDS favorably, suggesting improved comfort and reduced end-of-day dryness with this solution compared with their habitual solutions. Most individuals planned to continue using OPTI-FREE PureMoist, suggesting that it may provide additional benefit over their habitual solutions.
