Ophthalmol Update Jan ;16(4):923-6.

Objective: To assess the visual outcome of cataract surgery at Hayatabad Medical Complex (HMC) Peshawar on 1st, 3rd and 15th post-operative day and to categorize its visual acuity by World Health Organization (WHO) criteria. Methodology: The study was conducted from September to November 2015. 120 patients were enrolled for the study were above the age of 40. All patients were admitted through the OPD. 117(97.53%) patients were considered to have a good vision, 2(0.016%) were having borderline and none of the patients were having poor vision. Data was collected on a validated predesigned performa pre operatively on 1st, 3rd and 15th post operation day, and complications were treated accordingly and recorded for those patients who had their V.A less than 6/18 on 15th post-operative day after refraction was done in such cases if patient was not improving due to previous complications, their finding was recorded after thorough examination. Vision was finally recorded. Results: In total 120 patients were operated, males 87(72.5%), females 33(27.5%). Age group, 40-50 was 5(4.1%), 51-60 were 36(30%), in 61-70 were 56(46.6%), in 71-80 were 21(17.5%) and in 81-90 were 2(1.6%). Good vision was 75(62.5%), 35(29.16%) of them were on borderline and 8(6.66%) of them were having poor vision. According to WHO definition on 15th post-operative day 117(97.53%) were having good vision, 97% were borderline, 2(1.66%) were NPL due to endophthalmitis. Conclusion: Blindness due to cataract is a significant problem among the developing countries. The visual outcome of cataract surgery was 97%, which can be improved with adequate skills, facilities and quality control. The monitoring of quality outcome needs to be built into the data collection. The use of these indicators facilitates adequate management and evaluation of the efficiency and effectiveness of the intervention and can help to ensure the maximum utilization of the available resources for the cataract surgery.
