目的：分析上海奉贤东部地区65岁以上人群白内障患病率及手术现状。

方法：采用整体随机分层抽样方法。2015-01/12期间在奉贤东区四团镇、奉城镇对>65岁人群3 050名进行调查，采用统一眼科检查和问卷调查，其中眼科检查主要包括眼部裂隙灯显微镜检查和LogMAR视力表，了解接受白内障手术情况。

结果：受检者3 050名中，发现白内障1 244例，患病率为40.79%； 不同年龄的受检者患病率不同，随着年龄的增长，患病率不断升高。年龄组患病率差异有统计学意义(χ²=558.6，P<0.001)； 男性和女性的患病率分别是31.06%和49.94%，差异具有统计学意义(χ²=112.4，P<0.001)； 文盲(52.04%)与非文盲(38.76%)相比，差异有统计学意义(χ²=28.78，P<0.001)。接受白内障手术的患者为765例，手术覆盖率为61.25%； 年龄、性别差异不具有统计学意义，文化程度方面：非文盲盲人手术覆盖率明显远高于文盲的，差异具有统计学意义(χ²=39.72，P<0.001)。术后矫正视力≥0.3为脱残，术后矫正视力≥0.05为脱盲，脱残率为71.50%，脱盲率为95.29%，765只手术眼中，术后共29眼出现并发症，占总手术眼的3.79%。

结论：白内障是老年人常见的主要致盲眼病，上海奉贤东部地区老年人白内障患病率较高，虽近几年开展白内障复明工程以来，手术覆盖率有了一定提高，防治白内障仍然是防盲致盲工作的首要任务。

METHODS: In the period of January to December 2015, random stratified sampling in the whole group was taken in 3 050 people over 65 years, in Situan and Fengcheng, two towns at the Eastern District of Fengxian Town. Ophthalmologic examination and questionnaire survey were given to those people, including slit lamp microscopy and visual acuity(LogMAR)and the conditions on cataract surgery.

RESULTS: Totally 1244 cases of cataract were found in 3050 subjects, the prevalence rate was 40.79%. The prevalence rates in the subjects of different ages were different, as the age increases, the prevalence rate was rising. The difference of prevalence rate in different age groups was statistically significant(χ²=558.6, P<0.001); the prevalence rate of male and female were 31.06% and 49.94%, the difference was statistically significant(χ²=112.4, P<0.001); the rate of illiterate and literate was 52.04% and 38.76% respectively with significantly difference(χ²=28.78, P<0.001). Cataract surgery was taken in 765 cases, surgical coverage rate was 61.25%; difference on age, gender was not statistically significant; the degree of education: the rate in literate was significantly far higher than in the illiterate, the difference was statistically significant(χ²=39.72, P<0.001). Postoperative corrected visual acuity ≥0.3 was considered as removing from disable and postoperative corrected visual acuity ≥0.05 as removing from the blind. The rate removing from disable was 71.50%, the rate removing from the blind was 95.29%. In 765 eyes receiving surgery, postoperative complications occurred in 29 eyes, 3.79% of the total eye receiving surgery.

CONCLUSION: Cataract is the common blind causing disease in the elderly, and the prevalence rate of cataract in eastern Fengxian of Shanghai is high. Although in recent years, the Restoring Vision Project has been developed, the surgical coverage has been improved, and the prevention and control of cataract is still the primary task of blind prevention.
