青少年近视散光采用角膜塑形镜矫治的效果探讨

Discussion on effect of orthokeratology on adolescents with myopic astigmatism

目的探究青少年近视散光采用角膜塑形镜矫治的效果。方法100例(200眼)青少年近视散光患者作为研究对象,根据随机法分为对照组和观察组,各50例(100眼)。对照组采用普通框架镜矫治,观察组采用角膜塑形镜矫治。比较两组患者并发症发生情况、眼轴增长情况、球镜度增长情况、角膜曲率。结果观察组患者并发症发生率10.00%高于对照组的2.00%,差异有统计学意义(P<0.05)。矫治前,两组患者的眼轴增长比较差异无统计学意义(P>0.05);矫治1、2、3年,两组患者的眼轴增长均大于矫治前,但观察组患者的眼轴增长小于对照组,差异有统计学意义(P<0.05)。矫治前,两组患者的球镜度增长比较差异无统计学意义(P>0.05);矫治1、6、12个月,观察组患者球镜度增长分别为(0.91±0.52)、(0.57±0.34)、(0.34±0.17)D,均小于对照组的(1.49±0.57)、(1.17±0.26)、(0.83±0.20)D,差异有统计学意义(P<0.05)。矫治前,两组患者角膜曲率比较差异无统计学意义(P>0.05);矫治12个月后,观察组患者的角膜曲率为(39.02±0.17)D,低于对照组的(42.96±1.56)D,差异有统计学意义(P<0.05)。结论青少年近视散光采用角膜塑形镜矫治,可以取得较好的效果,但同时需要注意可能出现的一些并发症,需要加强对青少年佩戴方法的教育。

Objective To investigate the effect of orthokeratology on adolescents with myopic astigmatism.Methods A total of 100 cases(200 eyes)of adolescents with myopic astigmatism were selected as the research subjects and randomly divided into control group and observation group,with 50 cases(100 eyes)in each group.The control group was treated with ordinary spectacles,and the observation group was treated with orthokeratology.The complication rate,axial growth,sphericity growth and corneal curvature were compared between the two groups.Results The complication rate 10.00%in the observation group was higher than 2.00%in the control group,and the difference was statistically significant(P<0.05).Before correction,there was no statistically significant difference in the axial growth between the two groups(P>0.05).After 1,2 and 3 years of correction,the axial growth of the two groups was greater than those of this group before correction,but the axial growth of the observation group was less than that of the control group.All the differences were statistically significant(P<0.05).Before correction,there was no statistically significant difference in sphericity growth between the two groups(P>0.05).After 1,6,and 12 months of treatment,the sphericity growth in the observation group were(0.91±0.52),(0.57±0.34),(0.34±0.17)D,which were all less than(1.49±0.57),(1.17±0.26),(0.83±0.20)D in the control group,and the differences were statistically significant(P<0.05).Before correction,there was no statistically significant difference in corneal curvature between the two groups(P>0.05).After 12 months of treatment,the corneal curvature of the observation group was(39.02±0.17)D,which was lower than(42.96±1.56)D of the control group,and the difference was statistically significant(P<0.05).Conclusion Orthokeratology can achieve good results in the treatment of myopic astigmatism in adolescents,but at the same time,attention should be paid to some possible complications,and it is necessary to strengthen the education on the wearing method of adolescents.
