Background: Cataract is one of the leading cause of blindness in Indonesia and worldwide. Meanwhile the ability to carry out cataract surgery was not balanced by the increasing of cataract backlog of ± 70,000 per year. In addition to increase the number of cataract operations, it is very important to maintain the quality of surgery results by auditing the result of surgery. This study aims to evaluate post-operative visual acuity in social services organized by the Cataract Blindness Prevention Section of IOA Malang Branch in 2015-2017.Methods: This study is a retrospective study based on medical record data of cataract patients underwent cataract surgery at a social service organized by the Cataract Blindness Prevention Section of IOA Malang Branch in January 2015 - December 2017 period. Data collected included demographic data, preoperative and postoperative visual acuity, type cataract surgery, and intraoperative complications.Results: Cataract surgery carried out from 2015-2017 was 1,662 surgeries with 965 male patients (58.06%). Visual acuity before surgery was 1/300 in 583 patients (35.08%). The most cataract surgery procedure performed was SICS (60.17%). Vitreous prolapse was the most common complication found. There was a significant association between age and type of cataract surgery, with postoperative vision (p <0.05, α = 5%). From the analysis, the progress of post-operative visual acuity was found in 85.93% of patients and the results were significant (p <0.05, α = 5%).Conclusions: Cataract surgery may provide significant visual improvement that elevates vision and quality of life for patients.
