title: Visual outcome of cataract surgery.
abstract: The aim of this study was to assess whether the visual outcome of cataract surgery in the institution was in accordance with the World Health Organization recommendations. In this retrospective case series, all patients who underwent cataract surgery by a single surgeon from January 2009 till June 2011 were included. Date were collected from medical records on age, gender, visual acuity and causes of sub-optimal outcome. The main outcome was best-corrected visual acuity in the operated eye, measured 4 - 6 weeks after surgery. Data on visual outcome was grouped using WHO's classification. Of the 495 eyes that underwent cataract surgery, 58% were female. Overall, 93.3% of the operated eyes had good visual outcome, while 4.4% and 2.2% had borderline and poor outcomes, respectively. Pre-existing diseases accounted for 93.9% of the borderline/poor outcome. The study showed good visual outcome of cataract surgeries performed using phacoemulsification with intraocular lens (IOL) insertion.
