Purpose: The aim of this study was to evaluate the factors related to the postoperative visual prognosis in unilateral congenital cataracts.


Methods: Pars plana lensectomy and anterior vitrectomy was carried out in 18 children with unilateral congenital cataract. All children received hard contact lens correction and occlusion therapy after surgery. Postoperative visual function was assessed by Landolt visual acuity (V/A) and Titmus Stereo Tests.


Results: Four patients in the good acuity group achieved a V/A of 1.0 and 14 patients in the poor acuity group had V/A ranging from 0.02 to 0.4. Age at surgery significantly related to the postoperative V/A in the poor group but not in patients with good acuity.


Conclusion: We found that poor visual prognosis correlated with age at surgery performed after 3 months of age rather than with compliance to visual rehabilitation. Good visual prognosis in congenital cataract with early onset was attributed to very early surgery since a patient who had cataract extraction at 3 weeks of age attained a V/A of 1.0.
