  • Data are presented as the means±SEs.

  • *The differences in changes in cycloplegic refractive error and axial elongation between treatment groups were all statistically significantly different at 6 and 12 months.

  • AL, axial length; D, diopters; HAL, spectacle lenses with highly aspherical lenslets; SAL, spectacle lenses with slightly aspherical lenslets; SER, spherical equivalent refraction; SVL, single-vision spectacle lenses.
