title: Lens implantation surgery in the second eye.
abstract: In a series of 730 patients who underwent lens implant surgery, 44 (6%) had bilateral implants. Eighty-eight percent of these patients had at least one year's interval between operations and 50% more than two years. Surgery on the first eye resulted in vision of 20/40 or better in 86% of patients. Eighty-three percent of patients were 20/40 or better in the second eye following surgery. The principal cause of vision less than 20/40 was senile macular degeneration. Follow-up observation ranged from 4-96 months. Conservative criteria are advised for bilateral implant surgery, with an appropriate interval between operations considering the increased complexity of the implant procedure.
