目的：比较角膜塑形镜(OK镜)、多区正向光学离焦眼镜(DIMS)和单焦框架眼镜(SVS)对青少年近视的控制效果。

方法：回顾性研究。选取2020-04/2021-03于宁波爱尔光明眼科医院就诊的近视患者111例221眼，根据近视矫正方式分为OK组(42例83眼)、DIMS组(30例60眼)和SVS组(39例78眼)。随访24mo，记录并分析所有患者戴镜前后眼轴和等效球镜度变化情况。

结果：戴镜后6、12、18、24mo，三组患者眼轴均呈增长趋势，且SVS组患者眼轴增长量均高于OK组和DIMS组(P<0.01)。戴镜后24mo，角膜塑形镜的眼轴控制效果为59.7%，DIMS的眼轴控制效果为41.7%。戴镜后12、18、24mo，DIMS组和SVS组患者等效球镜度均呈增长趋势，且SVS组等效球镜度增长量均高于DIMS组(P<0.01)。戴镜后24mo，DIMS的近视度数控制效果为58.6%。

结论：角膜塑形镜和DIMS对青少年近视的控制均有较好的临床效果，且角膜塑形镜的控制效果优于DIMS。

METHODS: Retrospective study. A total of 111 myopic patients(221 eyes)in Ningbo Aier Guangming Eye Hospital from April 2020 to March 2021 were selected, and they were grouped into OK group(42 cases, 83 eyes), DIMS group(30 cases, 60 eyes)and SVS group(39 cases, 78 eyes)according to the method in myopia correction. All patients were followed up for 24mo, and the changes of axial length and spherical equivalent before and after treatment were recorded and analyzed.

RESULTS: After 6, 12, 18 and 24mo of treatment, the axial length grew in three groups of patients, and the growth of axial length in SVS group was higher than that in OK group and DIMS group(P<0.01). After 24mo of treatment, the control effect of axial length with OK and DIMS was 59.7% and 41.7% respectively. After 12, 18 and 24mo of treatment, the spherical equivalent increased in both DIMS and SVS groups, and the increase of spherical equivalent in SVS group was higher than that in DIMS group(P<0.01). After 24mo of treatment, the control effect of myopia with DIMS was 58.6%.

CONCLUSION: Both OK and DIMS showed good clinical effectiveness in the control of adolescent myopia, and the effectiveness of OK is better than that of DIMS.
