We report a case of stereopsis following early surgery for congenital monocular cataract. The patient was a 3.75-year-old girl who underwent early surgery for congenital monocular cataract at the age of 19 weeks and received an immediate gas-permeable hard contact lens fitting and occlusion therapy consisting of daily patching the sound eye for 6 hours. During the subsequent years, patching was increased to 50% to 80% of the waking day. Three years and two months postoperatively, she showed good visual acuity of 0.7 in the operated eye and also demonstrated stereoacuity of 1200 to 1500 seconds of arc in the Lang Stereotest or the TV-Random Dot Stereo test, duplicatably. From recent reports with excellent results of stereopsis, including this, we conclude that stereopsis is obtainable in patients undergoing congenital monocular cataract extraction by the end of month 2, contact lens fitting with a good compliance, and a progressive regimen of part-time occlusive therapy not to exceed 80% of the waking time.
