【摘要】：目的探讨角膜塑形镜对青少年近视眼视力、眼压及生物测量参数的影响。方法随机选取2013年1月至2015年12月在河北省眼科医院佩戴角膜塑形镜的青少年近视患者72例(136眼),年龄8~16岁,比较戴镜前,戴镜后1周、1个月、3个月和6个月视力、眼压、眼轴长度、角膜地形图、角膜厚度、前房深度的变化。结果佩戴角膜塑形镜后,患者的裸眼视力明显改善(P0.05),平均屈光度下降(P0.05);患者的非接触眼压降低(P0.05);眼轴长度较佩戴前变化不大(P0.05)。戴镜后前房深度较戴镜前未见明显变化(P0.05)。戴镜1周后角膜曲率较戴镜前下降(P0.05),其后角膜曲率趋于稳定;角膜厚度较佩戴前无明显变化(P0.05);角膜厚度较佩戴前减小(P0.05),其后3、6个月趋于稳定。结论角膜塑形镜可降低近视度数,提高裸眼视力,对青少年近视控制效果明显,佩戴角膜塑形镜后眼压及生物测量参数发生相应变化。
[Abstract]:Objective to investigate the effects of corneal plastic lens on visual acuity, intraocular pressure and biometric parameters of juvenile myopia. Methods A total of 72 cases (136 eyes) of juvenile myopia, aged 816 years, were randomly selected from January 2013 to December 2015 in Hebei Ophthalmology Hospital. The visual acuity and intraocular pressure were compared before, 1 week, 1 month, 3 months and 6 months after wearing the lens. Changes in axial length, corneal topography, corneal thickness and anterior chamber depth. Results after wearing corneal plastic lens, the naked visual acuity of the patients improved significantly (P0.05), the mean diopter decreased (P0.05), the non-contact IOP of the patients decreased (P0.05), and the length of the eye axis did not change much (P0.05). There was no significant change in anterior chamber depth after wearing mirror (P0.05). The corneal curvature decreased after 1 week (P0.05), then the corneal curvature tended to be stable; the corneal thickness did not change significantly (P0.05); the corneal thickness decreased compared with the pre-wear (P0.05); then, 36 months tended to be stable. Conclusion Corneal plastic lens can reduce the degree of myopia, improve the naked visual acuity, and control myopia in adolescents obviously. The intraocular pressure and biological measurement parameters after wearing corneal plastic lens can be changed accordingly.
