Better visual results, higher risks, seen with IOL after unilateral congenital cataract surgery

Aphakia correction after unilateral congenital cataract surgery with primary IOL implantation results in “improved visual acuity, improved binocular vision outcome and less occurrence of strabismus, but a higher rate of complications requiring reoperation,” according to a group of Czech researchers.

Rudolf Autrata and colleagues at Masaryk University in Brno reported their results in 41 children with unilateral congenital cataract who underwent cataract surgery with posterior capsulorrhexis and anterior vitrectomy. Eighteen of the patients had primary IOL implantation, and 23 were corrected with contact lenses. The mean age at time of surgery was 3.11 months; all patients were prescribed the same half-time reduced occlusion therapy.

Mean final VA in the operated eye was 0.43 (logMAR) for those who received an IOL and 0.58 for those who did not. The re-operation rate was 78% for those who received an IOL and 35% for those who did not.

The study is published in the March/April issue of Ophthalmologica.
