摘要
目的:探讨角膜塑形术对近视患者立体视觉、调节参数和眼生物学参数的影响。方法:分析2016-01/2017-05在我院接受治疗的65例130眼青少年近视患者的临床资料,按照等效球镜度分为高度近视组、中度近视组和轻度近视组。比较配戴角膜塑形镜前后近视患者立体视觉、调节参数和眼生物学参数的变化。结果:三组患者远近视力差值、立体视锐度、调节幅度、调节灵敏度水平比较,差异均有统计学意义(P<0.05)。近视患者治疗后裸眼视力(LogM AR)、球镜度数、柱镜度数明显低于戴镜前,差异均有统计学意义(P<0.05)。近视患者配戴角膜塑形镜后眼压、中央角膜厚度与戴镜前比较,差异无统计学意义(P>0.05)。戴镜后患者角膜曲率低于配戴前,差异有统计学意义(P<0.05)。眼轴长度高于治疗前,差异具有统计学意义(P<0.05)。结论:角膜塑形术可改善青少年患者的近视和散光,且能改善角膜曲率和延缓眼轴增长。
AIM:To investigate the effect of orthokeratology on stereopsis,accommodation parameters and ocular biological parameters in myopic patients.METHODS:The clinical data of 65 patients(130 eyes)with myopia in our hospital from January 2016 to May 2017 were analyzed and they were divided into high myopia group,moderate myopia group and slight myopia group.The changes of stereopsis,accommodation parameters and ocular biological parameters were compared between the myopic patients before and after the operation.RESULTS:The difference of distant vision,stereo acuity,accommodation range and accommodation sensitivity between the three groups were statistically significant(P<0.05).The uncorrected visual acuity,the degree of spherical equivalent and the diopter of cylindrical power in the myopic eyes were significantly lower than those before treatment,and the difference was statistically significant(P<0.05).The intraocular pressure and central corneal thickness were not different compared with before treatment(P>0.05).After treatment,the corneal curvature was lower and axial length were higher than those before treatment,the difference was statistically significant(P<0.05).CONCLUSION:Orthokeratology can obviously improve the distance and near vision and stereoscopic vision function of myopic patients,which may slow the increase of axis and reduce the corneal curvature.
