Orthoptic consequences of Binkhorst lens implantation for unilateral cataract.

Stereoacuity levels regained after uniocular lens implantation for unilateral cataract are related to the final visual acuity of the operated eye. They compare unfavorably with levels reported in normal populations and are unrelated to the period of monocularity and the residual optical defects of the operated eyes. Using random dot stereograms as a criterion, over a third of thirty-five patients remained stereoblind after treatment.
