Six years of wearer experience in children participating in a myopia control study of MiSight® 1 day


PURPOSE: To evaluate the experience of children wearing soft contact lenses (CLs) during a trial of MiSight® 1 day (omafilcon A, CooperVision, Inc.), a dual-focus myopia-control daily disposable CL. METHODS: A 3-year, double-masked, randomised trial (Part 1) comparing experiences with MiSight 1 day and a single-vision control (Proclear® 1 day, omafilcon A, CooperVision, Inc.) of neophyte, myopic children (ages 8-12). Treatment (n = 65) and control (n = 70) participants received lenses at sites in Canada, Portugal, Singapore, and the UK. Successful participants completing Part 1 were invited to continue for a further 3 years wearing the dual-focus CL (Part 2), and 85 participants completed the 6-year study. Children and parent questionnaires were conducted at baseline, 1 week, 1 month, and every 6 months until the 60-month visit, with children only also completing questionnaires at 66 and 72 months. RESULTS: Throughout the study, children reported high satisfaction with handling (≥89% top 2 box [T2B]), comfort (≥94% T2B), vision (≥93% T2B for various activities), and overall satisfaction (≥97% T2B). Ratings for comfort and vision were not significantly different between lens groups, visits, or study parts and did not change when children switched to dual-focus CLs. Ratings for 'really easy' or 'kind of easy' application improved from the outset for the neophytes (57% at 1-week follow-up and 85% at 1-month follow-up) and remained high throughout the study (visit: P = 0.007; part: P = 0.0004). Overall satisfaction improved in Part 2 (P = 0.04). Wearing times increased in Part 2 (14 vs. 13 hrs/weekday; 13 vs. 12 hrs/day on weekends; P < 0.001); there were no differences between groups. CONCLUSIONS: Children adapted rapidly to full-time wear, rated lenses highly, and rarely reported issues. The dual-focus optics included in the MiSight® 1 day lenses successfully achieved myopia control without lowering subjective ratings when fitted to neophytes or children refitted from single-vision CLs.
