Gross associated ocular defects were present in 129 of 231 eyes with congenital cataract. The visual results in these eyes were significantly poorer than in the eyes without such gross ocular defects.
The visual results for the patients on whom the operation was performed before 2
years of age were poorer than for those operated on after the age of 2
years.
The visual results were essentially the same whether the congenital cataract was complete or incomplete at the time of operation.
