目的探讨双眼白内障第一眼超声乳化手术前后生存质量的变化程度。方法综合分析国内外1990年1月～2008年11月间双眼白内障第一眼超声乳化手术前后生存质量比较的相关文献,对符合要求且资料完整的文献进行Meta分析。结果符合纳入标准的文献共4篇499眼。其纳入文献经异质性检验具有异质性,因而采用随机效应模型合并加权均数差及95%可信区间。其生存质量各方面的加权均数差及95%可信区间分别是:自理31.80(24.48～39.13);活动42.12(39.21～45.02);社交49.58(29.05～70.11);心理29.79(24.81～34.77);生存质量总分的加权均数差及95%可信区间是36.76(33.66～39.86)。结论双眼白内障第一眼超声乳化手术后患者的生存质量较手术前有显著改善。
Objective To explore the changes of the quality of life before and after phacoemulsification in the first cataract. Methods The related literatures about the quality of life before and after phacoemulsification were compared between January 1990 and November 2008 at home and abroad. Meta analysis was made on the documents that meet the requirements and the data were complete. Results A total of 499 eyes were included in the literature that met the inclusion criteria. The inclusion of heterogeneity in the literature by the heterogeneity test, so using random effects model combined weighted mean difference and 95% confidence interval. The weighted mean difference in all aspects of quality of life and 95% confidence interval were: self-care 31.80 (24.48-39.13), activity 42.12 (39.21-45.02), social 49.58 (29.05-70.11), psychology 29.79 (24.81-34.77) ; The weighted mean difference of total quality of life scores and 95% confidence interval were 36.76 (33.66 ~ 39.86). Conclusions The quality of life of patients after phacoemulsification in the first cataract is significantly improved compared with that before operation.
