Abstract

Purpose : Within a double masked randomized clinical trial, to assess adaptation and visual comfort in children wearing 2 different types of new spectacle lenses for myopia control, compared to single vision lenses (SVLs).

Methods : One hundred and sixty-seven children fulfilling the inclusion criteria (age 8-13 years, cycloplegic spherical equivalent refractive error: -0.75 to -4.75D) were randomly allocated to 24 months of wearing SVLs (55 children) or one of two types of new spectacle lenses containing concentric rings of contiguous aspherical micro-lenses (type 1: mildly aspherical micro-lenses, 56 children; type 2: highly aspherical micro-lenses, 56 children). A telephone or wechat interview 3 days and 2 weeks post dispensing assessed if children had adapted to the lenses. Visual comfort and ease of adaptation was evaluated by means of a 4 point likert-scale questionnaire given after 6 months post dispensing. Difference between each lens design was analysed using Kruskal-Wallis ANOVA.

Results : After 3 days of wearing the spectacle lenses 94%, 100% and 90% of children declared being adapted to SVLs, type 1 and type 2 lenses, respectively. After 2 weeks, all children declared being adapted to their lenses. Ease of adaptation did not differ between lens groups (p = 0.66), more than 96% of children judged adaptation being very easy or quite easy. There was also no difference in comfort between the three lenses: 94%, 96% and 94% of the children found SVLs, type 1 and type 2 lenses very comfortable or a little comfortable (p = 0.59), respectively. In addition, subjective perception of distance vision (p = 0.80), near vision (p = 0.53), motion (p = 0.42) and climbing of stairs (p = 0.40) were not affected by lens design.

Conclusions : Adaptation, quality of vision and visual comfort in children was comparable between single vision lenses and new lenses for myopia control during dispensing and 6 months of wearing.
