PURPOSE: To evaluate the 1-year myopia control efficacy of a spectacle lens with annular cylindrical microstructures.
METHODS: A total of 118 consecutive eligible children aged 8-12 years with -1.00 D to -4.00 D of spherical component myopia and <1.50 D astigmatism were enrolled between August 2020 and November 2020 at the Eye Hospital of Wenzhou Medical University. Participants were randomly assigned to wear cylindrical annular refractive element (CARE) (n = 61) or single-vision (n = 57) spectacle lenses. Cycloplegic autorefraction (spherical equivalent refraction [SER]) and axial length (AL) were measured at baseline and 6-month intervals. Adaptation and compliance questionnaires were administered during all visits.
RESULTS: Among 118 randomized participants, 96 (81.4%) were included in the analyses (mean [SE] age, 10.4 [0.6] years; 49 [51.0%] were female; mean [SE] spherical equivalent refractive error, -2.67 [0.66] D; mean [SE] axial length, 24.75 [0.77] mm). Adjusted 1-year myopia progression was -0.56 D for CARE and -0.71 D for single-vision spectacle lenses. The difference in progression was 0.14 D (95% CI, -0.04 to 0.32) for CARE vs single vision. Adjusted 1-year eye growth was 0.27 mm for CARE and 0.35 mm for single vision. The difference in eye growth was 0.09 mm (95% CI, -0.15 to -0.02) for CARE vs single vision. All groups adapted to their lenses with no reported adverse events, complaints, or discomfort.
CONCLUSIONS: Among children with myopia, treatment with cylindrical annular refractive element spectacle lenses significantly reduced the rate of axial elongation over 1 year compared with single-vision spectacle lenses.
