摘　　要：目的比较不同类型白内障患者术后晶状体后囊膜混浊发生率。设计回顾性病例系列。研究对象2007-2008年在石家庄市第一医院同一医师施行的超声乳化白内障吸除及人工晶状体植入术的2069眼。其中,单纯老年性白内障1574眼、糖尿病性白内障305眼、高度近视并发白内障165眼,陈旧性葡萄膜炎并发白内障25眼。方法于术后2年进行视力、裂隙灯、眼底检查,观察记录晶状体后囊膜混浊程度,并根据Hayashi方法进行混浊分级。主要指标晶状体后囊膜混浊发生率。结果单纯老年性白内障组后囊膜混浊128眼(8.13%),糖尿病性白内障组39眼(12.79%),葡萄膜炎并发白内障组4眼(16.00%),高度近视并发白内障组36眼(21.82%)。4个组比较,后囊膜混浊发生率之差异有统计学意义(χ2=35.377,P=0.000)。1级后囊膜混浊发生率各组相近:单纯老年组60眼(3.81%),糖尿病组6眼(1.97%),葡萄膜炎组1眼(4.00%),高度近视组5眼(3.03%);2级后囊膜混浊发生率糖尿病组较高,20眼(6.56%);3级后囊膜混浊发生率高度近视组较高,24眼(14.55%)。4组患者后囊膜混浊程度之间比较有显著差异(χ2=105.55,P=0.000)。结论单纯老年性白内障术后后囊膜混浊发生率较低,高度近视组后囊膜混浊发生率较高,混浊程度较重。Objective To compare the incidence of posterior capsule opacification （PCO） after surgery in the patients with differ- ent types of cataract. Design Retrospective case series. Participants 2069 eyes that accepted phacoemulsification and intraocular lens implantation by the same ophthalmologist from 2007 to 2008 in the First Hospital of Shijiazhuang. In which, 1574 eyes with simply se- nile cataract, 305 eyes with diabetic cataract, 165 eyes with cataract combined with high myopia, and 25 eyes with uveitis complicated cataract. Method The incidences of PCO in the patients with various types of cataract were recorded through observing visual acuity, split lamp and ocular fundus for 2 years after operation. The PCO was classified according to Hayashi＇s method. Main Outcome Mea- sures The incidence of PCO in patients with various types of cataract. Results In simply senile cataract group, diabetic cataract group, uveitis combined cataract group and high myopia combined cataract group, the incidence of PCO was 8.13% （128 eyes）, 12.79% （39 eyes）, 16.00% （4 eyes） and 21.82% （36 eyes）, respectively （X2=35.377, P=0.000）. The incidence of 1 level PCO among 4 groups was similar, 60 eyes/3.81% in simply senile cataract group, 6 eyes/1.97% in diabetic cataract group, 1 eye/4.00% in uveitis combined cataract group, and 5 eyes/3.03% in high myopia combined cataract group. The incidence of 2 level PCO in diabetic cataract group was higher （20 eyes/6.56%） and the incidence of 3 level PCO in high myopia combined cataract group was higher （24 eyes/14.55%） than in the other groups. Conclusion The incidence of PCO postopteratively in simply senile cataract group was significantly lower than other groups, but in high myopia combined cataract group was higher and the PCO was denser.
