โฆ Synopsis
Several studies have indicated that operation during the first months of life in children with dense congenital cataract improves the final visual acuity. In the current study seven otherwise healthy children operated on before the age of fifty-six days are compared with seven children operated on after the age of three months. The patients were followed by a team consisting of a paediatric ophthalmologist, a contact lens optician and an orthoptist. They were treated with contact lenses, spectacles with near addition and occlusion therapy when needed. Visual acuity was initially tested with preferential looking technique and later with Snellen optotypes. In the early treated group the visual development was almost normal with a final visual acuity of 20/20, while in the late treated group no patient obtained better visual acuity than 20/100. The findings indicate that dense congenital cataract should be treated before the age of three months.

Many tests of visual function have been proposed as means of preoperatively evaluating cataract patients' surgical outcomes. It is impractical to compare all of these tests simultaneously on the same group of patients. Quantitative reviews apply quantitative methods to comparisons across studies. We
Cataract patients whose surgical outcomes were in question were referred for testing by visual evoked potentials, elicited through closed eyelids by a luminance stimulus (flash) that appeared 10 times per second. Visual evoked potentials were rated as normal (predicted acuity of 20/50 or better) or
