MiSight Assessment Study Spain: A Comparison of Vision-Related Quality-of-Life Measures Between MiSight Contact Lenses and Single-Vision Spectacles

Abstract

Objectives: Recent research has shown that concentric contact lenses (CLs) can be a way to control the progression of myopia. The purpose of the current study was to compare vision-related quality-of-life measures in children wearing distance single-vision (SV) spectacles versus MiSight CLs, a specific concentric design for myopia control. Methods: Subjects aged 8 to 12 with myopia from 20.75 to 24.00 diopters (D) of sphere and astigmatism less than 1.00 D of cylinder were allocated to the lenses study group (MiSight) or control group (SV). A Pediatric Refractive Error Profile (PREP) questionnaire was administered at 12- and 24- month intervals to evaluate children’s perceptions in overall vision, near vision, far distance vision, symptoms, appearance, satisfaction, activities, academic performance, handling, and peer perceptions. The mean score of all items was calculated as the overall score. Results: In total, 74 children completed the study: n¼41 in the MiSight group and n¼33 in the SV group. In the MiSight group, the ratings at 12 and 24 months for appearance, satisfaction, effect on activities, handling, and peer perceptions were significantly better than those given by children in the SV group (P,0.001), as was the overall score. However, near vision was significantly better in the SV group at both 12 and 24 months (P,0.001). Conclusions: MiSight CL wear for controlling myopia improves visionrelated quality of life in children when compared with spectacle wear.
