Bilateral paediatric cataract surgery - outcomes of 298 children from Kinshasa, the Democratic Republic of the Congo

Abstract

Introduction: The leading cause of childhood blindness globally is paediatric cataract. Bilateral cataract surgery can help to improve visual performance and to diminish the burden of childhood blindness. Objective: To report in a retrospective observational cohort study the long-term outcomes of 298 children who had bilat- eral cataract surgery with IOL implantation from 2001-2016 in Kinshasa. Methods: A standardized surgical treatment of paediatric cataract was practiced on 298 children. Patient’s follow-up, com- plications, and visual outcomes were recorded and analysed. Results: The mean age was 5.7 ± 4.3 years and males were predominant (64.9%). Most of children were living mainly in urban poorest areas (96.3%). Strabismus, nystagmus and microcornea were encountered in 20.1%, 25.1% and 8.7% of children, respectively. Using WHO criteria most of patients were classified as blind preoperatively and 81.9% of them had improved visual outcomes after surgery. Main reasons for reduced vision during follow-up were secondary cataract (5.7%), IOL decentration (1.2%), retinal detachment (1.2%), and secondary glaucoma (1.5%). Conclusion: In spite of the post conflict challenges, elimination of cataract blindness in children remains a priority. Children present at a late age for surgery and long term follow-up is poor. There is need for program strengthening in these areas. Keywords: Paediatric cataract surgery; bilateral cataract; outcomes.
