摘要
目的对比不同角膜曲率患者配戴角膜塑形镜控制近视,延缓眼轴增长的疗效.方法采用回顾性病例分组对比研究方法,选取2017年1月到2020年12月于我院配戴角膜塑形镜2年的102例(204眼)青少年近视患者.按平坦角膜曲率分为平角膜曲率组和陡角膜曲率组两组,分别对戴镜前和戴镜2年后停戴1个月的等效球镜度、眼轴、角膜中央厚度、角膜内皮细胞计数进行测定.结果配戴治疗2年后比较,平角膜曲率组较陡角膜曲率组的等效球镜度和眼轴均明显增加(P<0.05).两组的角膜中央厚度和角膜内皮细胞计数分别比较,差异均无统计学意义(P>0.05).结论陡角膜曲率患者配戴角膜塑形镜控制近视和眼轴增长的疗效优于平角膜曲率患者,而角膜中央厚度和角膜内皮细胞计数变化无明显差异.及时配戴角膜塑形镜可有效控制近视和眼轴增长,避免高度近视引起眼底并发症.
Objective To compare the therapeutic effects of adolescents who suffered from different corneal curvatures by wearing a corneal shaping lens to control myopia and delay the growth of the ocular axis.Methods A retrospective case grouping comparative study was conducted.A total of 204 eyes of 102 adolescents with myopia admitted by our hospital were selected.These 102 adolescent patients had continuously worn corneal shaping lenses for two years from January 2017 to December 2020.The flat corneal curvature was categorized into two groups: the flat corneal membrane curvature group and the steep corneal curvature group.The equivalent sphericity, ocular axis, central corneal thickness, and corneal endothelial cell count were measured before wearing glasses.And the same tests were performed following by stopping wearing glasses for one month after two years of treatment.Results After two years of treatment, the equivalent sphericity and ocular axis in the flat angle membrane curvature group were significantly higher than those in the steep corneal curvature group(P<0.05). Comparison of mean central corneal thickness and mean corneal endothelial cell count between the two groups was not statistically significant(P>0.05).Conclusion The effectiveness of wearing a corneal shaping lens to control the progress of myopia and axial growth in the steep corneal curvature group was better compared with the flat angular membrane curvature group. However, there were no significant changes in central corneal thickness and corneal endothelial cell count.Wearing corneal shaping lenses in time can effectively control the progress of myopia and axial growth to avoid retinal complications caused by high myopia.
