Objective: The aim of this study was to compare the postoperative refractive outcome after cataract surgery between a hospital-based and an outreach-based cataract service centre. Methods: This study was conducted at the Hospital Selayang (HS), Selangor, Malaysia, a tertiary referral centre and an outreach-based cataract service centre (Pusat Pembedahan Katarak MAIWP, PPKM). Data was sourced from the Cataract Surgery Registry (CSR) in the National Eye Database (NED). Results: A total of 2318 surgeries were analysed. PPKM achieved postoperative refraction outcome within ±1.0D in 94.3 of cases compared with 88.4 in Selayang Hospital. Mean absolute prediction error was also better in PPKM (0.39±0.27D vs. 0.33±0.24D, p<0.001). Multivariate analysis showed that the tertiary hospital, persons of Chinese ethnicity, history of uveitis, previous history of ocular surgery and intraoperative complications as significant independent predictive factors for poor refractive outcomes. Conclusion: The outreach-based cataract service centre, which incorporates streamlined process designs and workflows, achieved superior refractive outcomes within ±1 dioptre after cataract surgery compared to a tertiary hospital. © 2021, Malaysian Medical Association.
