目的：评价甘肃省和政县年龄相关性白内障患者术后生活质量水平，并分析其影响因素。

方法：于2015-10/2016-02采取整群随机抽样的方法，将确诊为年龄相关性白内障并自愿接受小切口白内障摘除联合人工晶状体植入术的患者195例纳入本研究，分别于术前和术后6mo采用参考美国国立研究所开发的QOL问卷修订后制成的眼健康相关生活质量量表调查患者的生活质量情况。

结果：本研究最终回收有效问卷193份(99.0%)。将量表各维度总分的1/2作为此维度的正常生活质量水平，本组患者在身体运动功能、独立性/生活自理功能、社会角色和社会功能、精神心理健康维度得分均低于正常水平，且生活质量各维度得分均低于术前(均P<0.001)。视力损伤时间和双眼术后最佳矫正视力提高值对年龄相关性白内障患者术后生活质量影响显著。

结论：手术干预能够显著提高年龄相关性白内障患者的生活质量水平，视力损伤时间和双眼术后最佳矫正视力提高值是年龄相关性白内障患者术后生活质量的主要影响因素。

METHODS: Totally 195 cases of diagnosed age-related cataract patients who have voluntarily received SIECCE+IOL cataract surgeries were recruited in this study by cluster random sampling. Quality of life before and half year after the surgeries were studied by eye health related QOL scale developed and modified by referring to the questionnaires from National Institute of Research of the United States and India Aravind Eye Hospital.

RESULTS: One hundred and ninety-three questionnaires are valid for the study(99.0%). Half of total score of each dimension is defined as an average level of quality of life. The scores of study patients are all lower comparing to average level from perspective of physical function, independence/self-care function, social role and social function, psychological health. And the scores of all the dimensions of quality of life of postoperative patients are lower than those before surgeries(all P<0.001). Increased binocular best corrected visual acuity after surgery and visual impairment time influences significantly on the quality of life of patients after cataract surgery.

CONCLUSION: Surgical intervention can significantly improve the quality of life in age related cataract patients. Visual impairment time before surgery and the increased binocular best corrected visual acuity after surgery are the main influencing factors of postoperative quality of life in age related cataract patients.
