ICL手术对高度近视眼调节和非斜视性双眼视异常的影响探讨

The Effect of ICL Operation on Hypermyopia Accommodation and Non-Squint Binocular Vision Abnormality

目的:对于高度近视患者接受ICL手术治疗对眼调节以及非斜视性双眼视异常所产生的影响情况进行探讨。方法:选取2018年4月~2019年4月接诊的高度近视患者40例,所选患者全部接受ICL手术治疗,在手术前和术后6个月检查患者双眼视功能情况,分析手术前和术后6个月调节以及非斜视性双眼视功能变化。结果:40例高度近视患者接受ICL手术治疗之后没有抑制以及复视情况,手术之后全部获得稳定双眼视功能,手术治疗6个月之后的近距离水平隐斜(NLP)、在手术之后出现明显下降,和手术治疗之前对比存在显著统计学差异;调节性集合和调节比值(AC/A)以及调节幅度(AMP)和正相对调节(PRA)指标在手术之后出现明显升高,与手术之前对比存在显著统计学差异。结论:高度近视患者具有不同程度调节以及非斜视性双眼视异常,给予患者ICL手术治疗能够在保证屈光状态恢复正视基础之上,更好地改善双眼视功能,使患者获得舒适、清晰、稳定的视力。

Objective:To explore the influence of ICLon ocular adjustment and non strabismus binocular vision.Methods:40 patients with high myopia from April 2018 to April 2019 were selected,all of them were treated with ICL.The binocular visual function of the patients was examined before the treatment and 6 months after the treatment,and the types of accommodation and non strabismus binocular visual abnormalities before and after the operation were analyzed.Results:40 patients with high myopia did not have inhibition or diplopia after ICL operation.All patients obtained stable binocular vision function after operation,NLP decreased significantly and the AC/A,PRA and AMP increased significantly after operation.There was a significant statistical difference compared with before operation.Conclusion:The patients with high myopia have different degree of accommodation and non strabismus binocular vision abnormality.ICL can improve binocular vision function on the basis of ensuring the dioptric state to return to emmetropia,and the patients can acquire more comfortable,clear and stable vision.
