不同年龄阶段近视儿童佩戴多区近视离焦镜片的控制效果

Control Effect of Defocus Incorporated Multiple Segments Lens in Children with Myopia at Different Ages

目的观察不同年龄阶段近视儿童佩戴多区近视离焦(DIMS)镜片的控制效果。方法回顾性分析2019年12月至2020年12月在新乡医学院第三附属医院佩戴DIMS镜片的287例儿童,年龄7~15岁。按照首次佩戴DIMS镜片的年龄将其分为3组,其中7~9岁100例,10~12岁101例,13~15岁86例。比较3组儿童佩戴DIMS镜片前及佩戴6个月后等效球镜度、眼轴的变化情况,分析DIMS镜片对不同年龄阶段儿童的控制效果。结果佩戴DIMS镜片6个月后,3组儿童等效球镜度均增长,7~9岁组等效球镜度的增长幅度大于10~12岁组及13~15岁组(P<0.05)。10~12岁组的等效球镜度的增长幅度与13~15岁组相比,差异无统计学意义(P>0.05)。3组佩戴DIMS镜片后眼轴均出现增长,7~9岁组眼轴的增长幅度大于10~12岁组及13~15岁组(P<0.05)。10~12岁组眼轴的增长幅度与13~15岁组相比,差异无统计学意义(P>0.05)。结论10~15岁儿童佩戴DIMS镜片后近视控制效果较7~9岁儿童好。

Objective To observe the control effect of defocus incorporated multiple segments(DIMS)lens on children with myopia at different ages.Methods A retrospective analysis of 287 children aged 7-15 years who wore DIMS lenses in the Third Affiliated Hospital of Xinxiang Medical College from December 2019 to December 2020 was conducted.They were divide into three groups according to the age of first wearing DIMS lens,including 100 children aged from 7 to 9 years old,101 children aged from 10 to 12 years old,and 86 children aged from 13 to 15 years old.The changes of equivalent sphericity and eye axis of the three groups of children before and after wearing DIMS lenses for 6 months were compared,and the control effects of DIMS lenses on children of different ages were analyzed.Results After wearing DIMS lenses for 6 months,the equivalent sphericity of children of three groups increased,and the increase range of equivalent sphericity of 7-9 years old group was greater than that of 10-12 years old group and 13-15 years old group(P<0.05).There was no statistical difference in the increase range of equivalent sphericity between 10-12 years old group and 13-15 years old group(P>0.05).The eye axis of three groups increased after wearing DIMS lenses,the increase range of the eye axis of 7-9 years old group was greater than that of 10-12 years old group and 13-15 years old group(P<0.05).There was no statistical difference in the increase range of eye axis between 10-12 years old group and 13-15 years old group(P>0.05).Conclusion The myopia control effect of DIMS lens in children aged 10-15 years old is better than that in children aged 7-9 years old.
