title: Bilateral intraocular lens implantation.
abstract: A study of 1796 consecutive cataract patients in a posterior chamber intraocular lens implant (IOL) series revealed 373 patients (20.8%) who had bilateral IOLs. Visual acuity was 20/40 or better in 87% of first eyes operated and 90% in second eyes. The major cause of vision less than 20/40 was senile macular choroidal degeneration in both first and second eyes. The surgical reintervention rate was 11.8% in first eyes and 3.7% in second eyes. Ninety-two percent of patients had an interval of six months or more between surgery on the first and second eyes.
