目的：比较环曲面和球面角膜塑形镜对青少年中低度近视的控制效果。方法：回顾性分析2020-07/2021-06于上海德目佳苑眼科门诊部就诊并验配角膜塑形镜的中低度青少年近视患者169例290眼的临床资料，根据配戴的角膜塑形镜类型分为环曲面组(81例135眼)和球面组(88例155眼)。记录治疗前后视力和眼轴变化情况，评估治疗效果。结果：治疗后1a，环曲面组和球面组患者裸眼视力均较治疗前改善(P<0.01)，眼轴均较治疗前有所增长(P<0.01)，但两组间裸眼视力(0.014±0.043、0.017±0.047LogMAR)和眼轴增长量(0.18±0.22、0.19±0.22mm)均无显著差异(P>0.05)。结论：环曲面和球面角膜塑形镜均可提升中低度近视青少年裸眼视力，近视控制效果无显著差异。

AIM: To compare the control effects between toric-designed orthokeratology and spherical orthokeratology on adolescents with moderate-to-low myopia.METHODS: The clinical data of 169 adolescents(290 eyes)with moderate-to-low myopia in Jiayuan Outpatient Department of Shanghai Demu Ophthalmology from July 2020 to June 2021 were analyzed retrospectively. The patients were divided into toric group and spherical group according to the type of orthokeratology, with 81 cases(135 eyes)and 88 cases(155 eyes)respectively. The changes of visual acuity and ocular axis before and after treatment were recorded to evaluate the therapeutic effect.RESULTS: The uncorrected visual acuity of both groups significantly improved at 1a after treatment(P<0.01), and the axial length increased compared to that before treatment(P<0.01). But there were no significant differences in uncorrected visual acuity(0.014±0.043, 0.017±0.047LogMAR)and axial growth(0.18±0.22, 0.19±0.22mm)between the two groups(P>0.05).CONCLUSION: Both toric-designed orthokeratology and spherical orthokeratology can improve the uncorrected visual acuity of adolescents with low-to-moderate myopia, and there is no significant difference in controlling effect on myopia.
