Stereopsis after congenital monocular cataract extraction.

Congenital monocular cataract extraction was performed on a 1-day-old baby girl and a hydrophilic contact lens was fitted. A progressive regimen of part-time occlusive therapy was then instituted. Eight years later, the girl has a visual acuity of 20/25 in the operated-on eye and 50 seconds of arc of stereoacuity that has been confirmed by an independent pediatric ophthalmologist. This patient demonstrates the potential for high-grade stereopsis in congenital monocular aphakia.
