Description
2,049 cataract surgeries from eight rural secondary care centers in India were audited from October 2009 to March 2010. The dataset includes patient demographics, surgical procedures, complications, and visual acuity outcomes measured at discharge, 1–3 weeks, and 4–11 weeks post-surgery. It was collected by L V Prasad Eye Institute to evaluate factors associated with poor visual outcomes.
Use Cases
Predict poor visual outcome (BCVA <6/18) using risk factors like patient age, gender, and preoperative comorbidities.
Analyze the association between surgical procedure type (e.g., SICS with IOL, ECCE) and the rate of intraoperative complications.
Model visual acuity trends over time by comparing presenting visual acuity (PVA) and best-corrected visual acuity (BCVA) at discharge, 1–3 weeks, and 4–11 weeks follow-up visits.
Investigate gender disparities in surgical outcomes by analyzing the odds ratio for female patients having a poor visual outcome.
Strengths
Contains detailed pre- and post-operative data for 2,049 audited cataract surgeries.
Includes multivariable analysis results with specific odds ratios for key risk factors like age ≥70 (OR 4.63) and intraoperative complications (OR 8.01).
Follows WHO-recommended cataract surgical record for data entry, ensuring standardized collection.
Provides longitudinal outcome data with visual acuity measurements at three distinct post-operative time points.
Limitations
Data is from a specific 6-month period in 2009-2010 and may not reflect current surgical practices or outcomes.
Sample is limited to eight rural centers in India, limiting geographic and healthcare system generalizability.
Raw column definitions and sample data are unavailable, hindering immediate understanding of data structure.
