Objective: To analyze the changes of cataract surgery volume and related influencing factors in Shanghai during 2013 and 2015. Methods: The information of Cataract patients during the period of 2013 and 2015 was collected from Shanghai Cataract Operations Database. The cataract surgery volume and CSR of Shanghai residents and non-registered ones were compared. The cataract surgery volume and CSR of registered Shanghai residents in urban, suburban and exurban areas were calculated, respectively. In addition, the sources of surgery cost, hospitals where surgeries were performed were analyzed. Results: In Shanghai, the cataract surgery volume grew from 63 915 to 114 688 and the total CSR grow from 2 686 to 4 729 during the years between 2013 and 2015. In this period, the cataract surgery volume of registered Shanghai residents in urban, suburban and exurban areas increased from 27 203, 21 921, 8 847 to 46 415, 40 463, 18 171, respectively. The CSR1 (CSR of registered Shanghai residents) grew rapidly from 4 081 to 7 363, while the CSR2 (CSR of non-registered Shanghai residents) grew slowly from 619 to 949. According to statistics, 93.08% of the registered Shanghai residents paid the medical expenses with their medical insurance, while more than 80% non-registered Shanghai residents afforded it at their own expenses. The number of total CSR in urban, suburban and exurban areas increased from 5 085, 3 600, 3 205 to 3 600, 6 588, 6 513 respectively. In 2015, the number of cataract surgery cases in non-public hospitals exceeded that in public hospital, accounting for 54.71% of the total cataract surgeries. In the same year, 55.44% of the total cases come from suburban and exurban residents. Conclusions: From 2013 to 2015, there had been a dramatic increase in cataract surgery volume in nonpublic hospitals and exurban area in Shanghai, which effectively solved the problem of low CSR in suburban and exurban area, however the 1ow level of CSR of non-registered Shanghai residents was the key factor that significantly reduced the total CSR in Shanghai.

目的： 分析2013至2015年上海市白内障摘除手术的数量变化和影响因素。 方法： 调查研究。从"上海市白内障复明手术数据库"中收集上海市2013至2015年间白内障摘除手术的相关数据，计算白内障手术率（CSR），包括常住人口中的户籍人口与非户籍外来人口，城区、近郊、远郊户籍常住人口的白内障摘除手术量、CSR、手术方式、手术费用来源以及各地域医院手术量情况。 结果： 2013至2015年间，上海市每年白内障摘除手术的数量从63 915例增长到了114 688例，CSR从2 686增长到4 729。上海市城区、近郊、远郊户籍居民的白内障摘除手术数量分别从27 203、21 921和8 847例增长到46 415、40 463和18 171例。户籍常住人口CSR从4 081迅速增长为7 363，非户籍外来人口CSR增长缓慢，仅从619增为949，户籍常住人口手术费用中社会医疗保险比例达93.08%，非户籍外来人口手术费用中自费病例占80%以上。城区、近郊、远郊户籍常住人口CSR分别从5 085、3 600和3 205增长为8 708、6 588和6 513。白内障超声乳化吸除联合人工晶状体植入术是上海市白内障摘除手术的主要方式，占99%以上，人工晶状体植入占总体手术的比例也超过99%。2015年上海市非公立医院白内障摘除手术量首次超过公立医院，占上海市总手术量的54.71%。2015年非公立医院白内障摘除手术患者中55.44%为郊区人口。 结论： 2013至2015年上海市非公立医院和郊区人口中的白内障摘除手术量增长迅速，有效解决了郊区CSR低的问题；非户籍外来人口白内障摘除手术量低是制约上海市总CSR增长的主要因素。（中华眼科杂志，2018，54：580-585）.
