In 1984, our ophthalmology department switched from intracapsular cataract extraction (ICCE) to extracapsular cataract extraction (ECCE). We reviewed the postoperative incidence of retinal detachment (RD) in two consecutive series: (1) 604 eyes operated on by ICCE from 1982 to 1983 and (2) 1726 eyes operated on by ECCE from 1985 to 1986. Follow-up averaged 39 months in both groups. The RD incidence was 1.30% after ICCE and 0.41% after ECCE, a statistically significant difference. In both groups, the risk of RD was high for patients less than 70 years of age at the time of surgery but minimal for patients older than 70 years. The proportion of younger patients was significantly higher in the ICCE group (29.5%) than in the ECCE group (23.2%). When the data were stratified by age and the difference in age composition adjusted for statistically, the difference between the two groups in the incidence of postoperative RD was less pronounced. We conclude that although not significant at the 5% level after adjusting for age distribution, our results suggest a decreased risk of RD with ECCE.
1984年，我们眼科从囊内白内障摘除术（ICCE）转为囊外白内障摘除术（ECCE）。我们回顾了连续两个系列术后视网膜脱离（RD）的发生率：（1）1982年至1983年接受ICCE手术的604只眼，以及（2）1985年至1986年接受ECCE手术的1726只眼。两组的平均随访时间均为39个月。ICCE术后RD发生率为1.30%，ECCE术后为0.41%，差异有统计学意义。在两组中，手术时年龄小于70岁的患者发生RD的风险较高，而70岁以上患者的风险极小。ICCE组年轻患者的比例（29.5%）明显高于ECCE组（23.2%）。当数据按年龄分层并对年龄构成差异进行统计学调整后，两组术后RD发生率的差异就不那么明显了。我们得出结论，尽管在调整年龄分布后未达到5%的显著水平，但我们的结果表明ECCE术后RD风险降低。
