Purpose: The method of the aphakic correction after unilateral cataract extraction during infancy is controversial. Some ophthalmologists advocate correction with a contact lens (CL), whereas others recomended an intraocular lens (IOL) correction. We compared visual acuity, ocular alignment, retreatment rate and binocular vision outcomes in children treated with these two methods at our clinic.
Method: This study included 41 children with a unilateral congenital cataract who had cataract surgery with posterior capsulorhexis and anterior vitrectomy, coupled with (IOL group, n = 18) primary IOL implantation or without (CL group, n = 23). All infants undergone the first surgery during 12 months of their life and they were operated in the period from 1994 to 1999. The mean age at surgery was 3.11±2.65 months (range: 28 days to 11 months. All patients were prescribed the same half-time reduced occlusion therapy. Good parents cooperation and good compliance with patching were the necessary conditions to include a patients into the study. In January to February 2003, the final visual acuity and binocular vision outcomes were assessed.
Results: The mean final visual acuity for the operated eye was 0.78 ± 0.31 for the IOL group and 0.57 ± 0.36 for the CL group (P = 0.092). The me
