Purpose : To report the visual outcome of hundred thousand cataract surgeries done at Rural Secondary centres.

Methods : L V Prasad Eye Institute (LVPEI) has a network of rural eye centres in Southern and Eastern India. Data collected from electronic medical records for demographics – age, gender, economic status (paying and non-paying); eye operated, surgical techniques (Phacoemulsification or Manual small incision cataract surgeries MSICS), surgeon category (faculty, fellows & residents), intraoperative complications, associated ocular & systemic diseases, Preoperative presenting Visual Acuity (PVA) and postoperative Uncorrected (UCVA) & Best Corrected Visual Acuity (BCVA) between 3-11 weeks is reported along with risk factors for poor outcomes (defined as BCVA of 6/12 or less at last FU).

Results : From January 2016 to December 2020, 123685 cataract surgeries performed in 20 centres. Mean age of patients was 63 years; 71542(57.84%) were females. 82% were MSICS, 54.5% were in right eye, 60.77% were non-paying; 7.86% (ocular) & 5.22% (systemic) had comorbidities. 2.77% patients had intraoperative complications. Fellows did 70% of surgeries. Preop PVA of <3/60 was noted in 53300 (43.09%). 98,999 (80%) patients were available at last FU; ≥ 6/12 of UCVA in 66443 (67.11%) and BCVA in 90191 (91.1%). A significant difference was noted for age category, paying status, IOL status, surgeon category, ocular disease, eye & surgical technique for poor versus good outcomes. On multivariate analysis, variables (odds ratio OR) which are significant for poor visual outcome of BCVA <6/12 are: age of 60-69years (OR 1.43), ≥70years (OR 2.58) , females(OR 1.07), nonpaying patients(OR 1.12) , left eye(OR 0.71), MSICS(OR 1.92), presence of intraoperative complications (OR 1.97), ocular disease (OR 2.71), presence of ACIOL (OR 3.24) or aphakia (OR 9.22) and surgeries by fellows (OR1.11).

Conclusions : This study shows that it is feasible to achieve BCVA of 6/12 or better in 91% of patients in rural setup. More than 90% of surgeons achieved it. The possibility of achieving good visual outcome in rural setup with proper training of the fellows and residents with proper case selections for them, is important to achieve good visual outcome in these patients.
