Outcome of cataract surgery in rural areas of Kaduna State, Nigeria

Abstract

To evaluate the visual outcome of all patients who had cataract surgery with intraocular lens implant in five Local Government Areas (LGAs) of Kaduna State and to identify reasons for poor outcome and to proffer suggestions to improve outcome. A prospective study using the WHO cataract surgery record form to collect data from consecutively screened and operated cataract patients over a period of 18 months (January 2006-June 2007). Data was analysed using Monitoring Catarct Surgery Outcome V2.3 software by the WHO. A total of 690 eyes of 644 patients were operated, ECCE+PCIOL implantation was achieved in 664 (96.2%) while 26(3.8%) had anterior chamber lens implant. The age range was 40 - 99 years and male to female ratio was 1: 0.9. Good outcome was obtained in 239 (34.6%) and 370(53.6%) of patients at 2 and 8 weeks respectively in the postoperative period. Surgical complications like striate keratopathy/corneal oedema (18.3%), cortical reminant (4.2%) and posterior capsular rupture (2.9%), and uncorrected refractive error were identified as reasons for poor outcome. A good outcome of greater than 80% at 8 weeks postoperative period was not achieved. Provision of postoperative correction of residual ametropia in the rural community, as well as improved surgical techniques of surgeons, will go a long way to improve the visual outcome and cataract surgery uptake.
