Abstract
We reviewed 604 eyes in 521 patients who had intracapsular cataract extraction. The follow-up period averaged 39 months. The incidence of rhegmatogenous aphakic retinal detachment (ARD) was 1.3% in the whole group. The ARD incidence was 1.0% in eyes without surgical complications and 5.4% in myopic eyes (myopia defined as an aphakic refraction ≤ + 9.0 diopters). The log-rank test was used to estimate the statistical significance of various ARD predictors. Significant predictors were age at surgery below 70 years (P=.0004) and myopia (P=.001). Our results indicate that the high risk of ARD is concentrated in a small group of myopic patients operated on at a relatively early age. During the follow-up period, 128 patients died. Compared with the mortality rate of the entire Danish population, this was not an above average mortality rate. Thus, our results do not support the hypothesis that senile cataracts reflect general systemic deterioration rather than local eye disease.
