Abstract

Purpose: The aim of this study was to investigate the effect of individualized ocular refraction customized (IORC) spectacle lenses with different actual amounts of peripheral myopic defocus (MD) on myopia control over 1 year. These lenses compensate for the original peripheral refraction via the free-form surface on the back of the lens.

Methods: This 1-year, double-masked randomised clinical trial included 184 myopic schoolchildren aged 8-12 years. Participants were randomised to receive IORC lenses with high (IORC-H group, +4.50 D), medium (IORC-M group, +3.50 D) or low (IORC-L group, +2.50 D) MD or single-vision (SV) lenses. The spherical equivalent refractive error (SER) and axial length (AL) were measured at baseline and 6-monthly intervals.

Results: After 1 year, the mean (SD) changes in SER were -0.18 (0.37), -0.36 (0.37), -0.52 (0.39) and -0.60 (0.42) D for the IORC-H, IORC-M, IORC-L and SV groups, respectively. Compared with the SV group, the effects of slowing myopia progression were 70%, 40% and 13% for the IORC-H (difference of 0.47 D, p < 0.001), IORC-M (difference of 0.32 D, p = 0.001) and IORC-L (difference of 0.15 D, p > 0.05) groups, respectively. The mean (SD) changes in AL were 0.12 (0.16), 0.23 (0.17), 0.29 (0.17) and 0.36 (0.17) mm for the IORC-H, IORC-M, IORC-L and SV groups, respectively. The axial elongation was 67%, 36% and 19% lower in the IORC-H (difference of 0.25 mm, p < 0.001), IORC-M (difference of 0.15 mm, p < 0.001) and IORC-L (difference of 0.10 mm, p = 0.04) groups, respectively, compared with the SV group. The IORC-H group exhibited significantly less axial elongation than the IORC-M and IORC-L groups (p = 0.01 and p < 0.001, respectively).

Conclusion: Compared with the IORC-M and IORC-L lenses, the IORC-H lens was found to have superior efficacy in inhibiting myopic progression and slowing eye growth in schoolchildren, with better myopia control efficacy in younger children.

个体化屈光度定制眼镜对学龄儿童近视控制的影响：为期一年的随机临床试验。

目的：本研究旨在探讨不同实际周边近视离焦（MD）量的个体化眼屈光定制（IORC）眼镜在一年内对近视控制的影响。这些镜片通过镜片背面的自由曲面补偿原有的周边屈光度：这项为期一年的双掩蔽随机临床试验包括 184 名 8-12 岁的近视学童。参与者被随机分配接受高（IORC-H 组，+4.50 D）、中（IORC-M 组，+3.50 D）或低（IORC-L 组，+2.50 D）MD 的 IORC 镜片或单视（SV）镜片。基线和每 6 个月测量一次球面等效屈光度（SER）和轴向长度（AL）：1年后，IORC-H、IORC-M、IORC-L和SV组的球面等效屈光度（SER）的平均（标度）变化分别为-0.18（0.37）、-0.36（0.37）、-0.52（0.39）和-0.60（0.42）D。与 SV 组相比，IORC-H 组减缓近视发展的效果分别为 70%、40% 和 13%（差异为 0.47 D，P 0.05）。IORC-H组、IORC-M组、IORC-L组和SV组的AL平均（标清）变化分别为0.12（0.16）、0.23（0.17）、0.29（0.17）和0.36（0.17）毫米。IORC-H 组的轴向伸长率分别降低了 67%、36% 和 19%（差异为 0.25 毫米，p 结论）：与 IORC-M 和 IORC-L 镜片相比，IORC-H 镜片在抑制学龄儿童近视度数加深和减缓眼球增长方面具有更好的疗效，对年龄较小的儿童具有更好的近视控制效果。
