摘　　要：[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 know the effects of the cataract surgery,explore the main reasons of visual acuity after cataract surgery,and find ways for improving the visual acuity of cataract patients.[Methods] A survey of 935 patients with cataract surgery in Sichuan was taken by stratified cluster random sampling method.Chi-square test was used for describing and analyzing the distribution of the patients＇s situation.Logistic regression was used for the main reasons analysis.[Results] 44.06% of the 935 cataract operated eyes had presenting visual acuity 6/18 or better than 6/18.77.86% of the 935 cataract operated eyes had corrected vision acuity 6/18 or better than 6/18.This was far lower than the standard which developed by WHO.Results from the univariate analysis showed that the preoperative poor eyesight was associated with surgical methods,postoperative refractive error situation,postoperative corneal situation,postoperative oculopupillary situation,postoperative intraocular lens situation,PCO/after cataract,postoperative vitreous situation and the situation of eye fundus.Results from the multivariate analysis showed that the preoperative poor eyesight was associated with surgical methods,postoperative refractive error situation,postoperative intraocular lens situation,PCO/after cataract and the situation of eye fundus.[Conclusion] Implementing the surgical with IOL,correcting the refractive errors effectively,giving treatment to PCO/after cataract and the abnormal of the eye fundus will make an important contribution to improve the visual acuity of cataract patients.
