方法：采用回顾性方法，对334例334眼接受贫困白内障复明手术的患者进行基本情况、术前及术后1wk视力、术中并发症、术后并发症的病历采集及现场调查，对其中83例进行视功能和生存质量调查，225例贫困白内障患者和120例非贫困白内障患者进行手术成本/效果的对比分析，使用多重线性回归模型及Logistic回归模型进行术后视力影响因素分析。

结果：患者术后1wk视力明显高于术前视力(P<0.05)，其中术后1wk视力≥0.5的为235例(70.4%)、视力<0.05的为16例(4.8%)。多重线性回归分析显示，眼部其他疾病、白内障分类是术后视力的影响因素。logistic回归分析显示，术前视力低、眼部有其他疾病是术后低视力的危险因素，其OR值及其95%CI依次为6.5(2.8-14.8)和1.3(1.0-1.6)。术后视功能以及生存质量均高于术前。贫困白内障患者手术成本/效果低于非贫困白内障。

结论：贫困白内障患者术后视力、视功能明显提高，且手术成本低，显著改善了生活质量。

METHODS: Retrospectively, 334 eyes of 334 patients were reviewed. Visual function and quality of life questionnaires were available in 83 patients. The cost/effectiveness of cataract surgery was analyzed in 225 patients with LSES and 120 patients who received standard cataract surgery. Multiple linear regression analysis and logistic regression analysis were used to assess the factors affecting the postoperative visual acuity.

RESULTS: At 1wk postoperatively, uncorrected visual acuity(UCVA)was improved significantly compared to these preoperatively(P<0.05), 235 eyes(70.4%)had UCVA of 20/40 or better, and 16 eyes(4.8%)had UCVA worse than 20/400. Multiple linear regression analysis revealed that other ocular diseases and cataract classification were factors contributing to postoperative UCVA. Logistic regression analysis showed that low preoperative visual acuity and other ocular diseases were risk factors of postoperative low vision, and the odds ratio(95% confidence interval)values were 6.5(2.8-14.8)and 1.3(1.0-1.6), respectively. Visual function and quality of life were significantly improved after the surgery. The cost/effectiveness of cataract surgery in patients with LSES was lower than that in standard cataract patients.

CONCLUSION: Visual acuity and visual function were significantly better after the surgery in cataract patients with LSES, and the operation cost was low. Quality of life in these patients was significantly improved.
