目的：比较球面与环曲面角膜塑形镜对青少年中低度近视伴散光(-1.00--1.50 DC)的控制效果。

方法：回顾性分析2021-06/2022-01于四川省人民医院眼科就诊并验配角膜塑形镜中低度青少年近视伴散光(-1.00--1.50 DC)患者119例119眼的临床资料，根据配戴的角膜塑形镜类型分为球面组65例65眼和环曲面组54例54眼。记录患者戴镜前后裸眼视力(UCVA)、眼轴及角膜散光变化情况，评估治疗效果。

结果：戴镜1、2 a后球面组和环曲面组各组UCVA均较戴镜前有改善(均P<0.01)，角膜散光有降低，但无显著差异(均P>0.05)，眼轴均较戴镜前增长(P<0.01)。戴镜前后球面组与环曲面组UCVA、角膜散光比较无差异(F_组间=0.829，P_组间=0.364； F_组间=0.997，P_组间=0.320)。球面组与环曲面组眼轴增长量比较，戴镜1 a后(0.18±0.11 mm vs 0.17±0.14 mm)、戴镜2 a后(0.17±0.10 mm vs 0.16±0.10 mm)均无显著差异(均P>0.05)。

结论：中低度近视伴散光(-1.00--1.50 DC)的青少年配戴球面和环曲面角膜塑形镜均可改善UCVA，降低角膜散光，延缓眼轴增长，球面与环曲面设计的角膜塑形镜对近视的控制效果无显著差异。

METHODS: The clinical data of 119 cases(119 eyes)of low-to-moderate myopia with astigmatism(-1.00--1.50 DC)adolescents who were treated and fitted with orthokeratology in the ophthalmology department of Sichuan Provincial People's Hospital from June 2021 to January 2022 were retrospectively analyzed. They were divided into spherical group, with 65 cases(65 eyes), and toric group, with 54 cases(54 eyes)according to the type of orthokeratology. The changes of uncorrected visual acuity(UCVA), axial length and corneal astigmatism before and after wearing lenses were recorded to evaluate the therapeutic effect.

RESULTS: The UCVA of both the groups significantly improved at 1 and 2 a after wearing lenses(all P<0.01); corneal astigmatism decreased, but there was no significant difference(all P>0.05); the axial length was longer than that before wearing lenses(P<0.01). There were no statistical significant differences in the UCVA and corneal astigmatism between the spherical group and the toric group(F_intergroup=0.829,P_intergroup=0.364; F_intergroup=0.997,P_intergroup=0.320); and there were no statistical significant differences in the axial length growth between the spherical group and the toric group after wearing lenses for 1 a(0.18±0.11 mm vs 0.17±0.14 mm), and 2 a(0.17±0.10 mm vs 0.16±0.10 mm; all P>0.05).

CONCLUSION: Both orthokeratology lenses can improve the UCVA, reduce corneal astigmatism, and delay axial length growth of adolescents with low-to-moderate myopia with astigmatism(-1.00--1.50 DC), and there are no significant differences in the control effect of spherical design orthokeratology and the toric design orthokeratology on myopia.
