title: Epidemiologic aspects of senile cataract extraction stratified by visual acuity, age, and sex.
abstract: A review of records for 221 patients 50 years old and older undergoing first cataract extractions showed that women constituted 64% of this population (142 cases). The men had a mean age of 70.8 years and the women a mean age of 71.8 years. This difference was not significant. Men had a significantly (P less than .05) better mean best corrected visual acuity preoperatively than women (20/100 vs 20/400). In the two younger groups (those aged 50 to 59 years and those aged 60 to 69 years), men also had significantly (P less than .05) better preoperative visual acuities.
