[目的]了解白内障复明术后效果,探讨引起白内障术后视力低下的主要原因,找到提高白内障病人术后视力的途径。[方法]采用分层整群随机抽样方法,对四川三地市的935名白内障术后患者进行现场调查。采用χ2检验对调查人员术前及术后情况进行描述和分析;采用多因素Logistic逐步回归分析术后视力低下主要原因。[结果]四川三地白内障术后视力术后裸眼视力≥6/18占全部调查人数的44.06%,而术后矫正视力≥6/18的占全部调查人数的77.86%,低于WHO规定的标准,术后效果不佳。单因素分析显示手术方式、术后屈光不正情况、术后眼睑情况、术后角膜情况、术后瞳孔情况、术后人工晶体情况、后发障情况、术后玻璃体情况以及术后眼底情况在视力低下组和视力正常组间差异均有统计学意义;多因素分析显示,手术方式、术后屈光不正情况、是否安装人工晶体、后发障情况以及术后眼底情况是白内障患者术后发生视力低下主要原因。[结论]推行晶体植入的手术方式,矫正屈光不正,积极治疗术后发生的后发障以及眼底病变将对促进白内障患者术后视力提高有重要意义。
[Objective] To understand the postoperative effects of cataract surgery, investigate the main causes of visual acuity after cataract surgery, and find ways to improve postoperative cataract patients’ visual acuity. [Methods] A stratified cluster random sampling method was used to investigate 935 cataract patients in three cities of Sichuan Province. The χ2 test was used to describe and analyze the investigators’ preoperative and postoperative conditions. The main causes of postoperative visual acuity were analyzed by multivariate Logistic stepwise regression. [Results] Visual acuity of uncorrected visual acuity after cataract surgery in three places in Sichuan Province accounted for 44.06% of the total number of patients, while the corrected visual acuity of 6/18 accounted for 77.86% of the total, less than the WHO standard , Poor results after surgery. Univariate analysis showed that the operation method, postoperative refractive error, postoperative eyelid, postoperative cornea, postoperative pupil, postoperative intraocular lens, postoperative obstacle, postoperative vitreous and postoperative fundus in There was significant difference between low vision group and normal vision group. Multivariate analysis showed that the operation method, postoperative refractive error, whether to install intraocular lens, postoperative obstacle and postoperative fundus were the occurrence of postoperative cataract The main reason for poor eyesight. [Conclusion] It is of great significance to promote the visual acuity after cataract surgery by implementing the operation mode of crystal implantation, correcting the refractive error, and actively treating the posterior obstacle and the retinopathy.
