Congenital cataract is the most common cause of preventable blindness in children. The aim of this study is to evaluate the refractive and functional prognosis of children operated for congenital cataract with implantation. This is a retrospective study of 94 children, including 73 bilateral cataracts, 21 unilateral operated between 2009 and 2013. The refraction was measured at 1 month, 3 months, 6 months, 1 year, 2 years, 3 years and / or 4 years postoperatively. The best corrected visual acuity, as well as the incidence of postoperative complications were analyzed. The average age of surgery was 25 months with an average follow-up of 3.17 years. The complications found were inflammation, secondary proliferation, and glaucoma. Final corrected mean visual acuity (VA) was 5.75 / 10th for bilateral forms, and 4.16 / 10th for unilateral. The poor prognostic factors found were the late age of surgery, the density of cataracts and the occurrence of complications. The incidence of postoperative complications was significantly higher in children operated at a young age. The factors of poor visual prognosis in children operated for congenital cataract with implantation, are represented by the unilateral nature of the cataract, the late age of the surgery, the density of the cataract and the occurrence of postoperative complications.
