摘要

摘要: 目的研究高中青少年在佩戴夜戴型角膜塑形镜后对角膜形态的早期变化。方法选取深圳市龙岗区第五人民医院2014年9月-2015年9月符合佩戴夜戴型角膜塑形镜标准的青少年近视患者60例117眼,并根据初诊时患者的近视程度将患者分为A组(58眼,近视 ≤ -3.00 D)和B组(59眼,-3.00 D<近视 ≤ -6.00 D)。所有患者在戴镜前、戴镜后的1 d,1周,1、3、6个月;1、1.5、2年定期对裸眼视力、角膜曲率、眼轴长度、眼压等各项进行复查。结果 2组患者在佩戴夜戴型角膜塑形镜后1 d的裸眼视力均有大幅度提高,戴镜后1周基本趋于稳定,角膜曲率均较戴镜前变平,角膜厚度也均有不同程度的变薄现象,戴镜1、3、6个月后基本趋于稳定,其中B组患者的治疗效果较A组更加显著,差异具有统计学意义(P<0.05)。2组患者虽在佩戴夜戴型角膜塑形镜后均有不同程度的干眼症状出现,但角膜的各形态变化包括眼轴长度、前房深度和眼压等各项与戴镜前相比,差异无统计学意义(P>0.05)。结论佩戴夜戴型角膜塑形镜能在短期时间内提高患者裸眼视力,阻止近视的发展,且控制中度近视患者的疗效较低度近视患者更加明显,是一种安全、快速、有效的治疗青少年近视的方法,值得在临床中推广。

Abstract: Objective To study the early changes of corneal morphology in high school adolescents wearing overnight orthokeratology. Methods A total of 60 adolescent myopia patients (117 eyes) meeting the standards of wearing overnight orthokeratology in our hospital from September,2014 to September,2015 were enrolled and divided into group A (58 eyes,myopia ≤-3.00 D) and group B (59 eyes,-3.00 DResults The uncorrected visual was improved significantly one day after wearing overnight orthokeratology in both groups,and became more stable one week later.The corneal curvature recovered as compared with that before wearing the glasses,and the thickness of cornea got thinner with different degrees,and became more stable 1,3 and 6 months later.The curative effect of group B was more obvious as compared with group A with a statistically significant difference (P<0.05).Through with varying degrees of dry eye symptoms,the changes of corneal morphology including optic axial length,anterior chamber depth and intraocular pressure were not significant as compared with those before wearing the glasses in both groups (P>0.05). Conclusion To wear overnight orthokeratology can in a short time improve the uncorrected visual acuity and prevent the development of myopia,especially for the moderate myopia,it is a safe,fast and effective treatment for adolescent myopia,and worth popularizing in clinical use.
