Population-based study of cataract surgery among patients with type 2 diabetes in Kinmen, Taiwan.
BACKGROUND
The purpose of this study was to assess the prevalence and associated factors of cataract surgery among patients with type 2 diabetes in Kinmen, Taiwan.


METHODS
A community-based population survey between 1991 and 1993 identified 971 patients over the age of 30 years with type 2 diabetes. In 1999, a total of 578 patients (59.5%) with type 2 diabetes from the population were examined in an ophthalmic screening study. Two senior ophthalmologists employed slit-lamp biomicroscopy, indirect ophthalmoscopy, and retinal photographs with pupil dilatation to examine the patients' lenticular and retinal status.


RESULTS
The prevalence of cataract surgery in one eye, both eyes, and any cataract surgery among patients with type 2 diabetes was 4.5%, 5.4%, and 9.9%, respectively. The prevalence of cataract surgery in women (11.3%) was not significantly higher than in men (7.7%), but there was a statistical increase with age (p = 0.001, chi2 trend test). Multiple logistic regression showed that age (OR 1.13, 95% CI 1.07-1.19) and diabetic retinopathy (OR 4.68, 95% CI 1.94-11.33) were independent factors associated with cataract surgery.


CONCLUSIONS
Age and diabetic retinopathy were associated with prevalence of cataract surgery among persons with type 2 diabetes.
