During 1987 and 1988 all patients undergoing a cataract extraction at the eye Clinic of Sahlgrenska University Hospital were registered to determine the yearly incidence of cataract extractions according to sex and age. We found that after the age of 70 years the incidence of cataract extractions was higher for females than males. This difference was most pronounced for operations of the first eye. In this case the relative risk to undergo a cataract extraction for a woman compared to a man was 1.71 with 95% confidence interval 1.51-1.94, which showed a significantly increased risk. The preoperative VA of the best eye at the time of the first operation did not differ significantly between older men and women, indicating that women had no tendency to come earlier to operation. Our results show that after the age of 70 years the operation incidence of women is significantly higher than for men. This probably reflects a generally increased prevalence of various stages of cataract among females above 70 years in a Nordic population.
1987年至1988年期间，对在萨尔格伦斯卡大学医院眼科诊所接受白内障摘除手术的所有患者进行了登记，以确定按性别和年龄划分的白内障摘除年发病率。我们发现，70岁以后，女性白内障摘除的发病率高于男性。这种差异在第一眼手术中最为明显。在这种情况下，女性接受白内障摘除手术相对于男性的相对风险为1.71，95%置信区间为1.51 - 1.94，这表明风险显著增加。首次手术时最佳眼的术前视力在老年男性和女性之间没有显著差异，这表明女性没有更早前来手术的倾向。我们的结果表明，70岁以后女性的手术发病率显著高于男性。这可能反映了北欧人群中70岁以上女性白内障各个阶段的总体患病率普遍增加。
