Purpose To report trends in cataract surgery indications, visual acuity outcomes, complication rates and reoperation rates at ten Aravind Eye Hospitals in Tamil Nadu, India. Methods In this retrospective database study we analyzed seven years of data of cataract surgeries at Aravind during January 1, 2012 to December 31, 2018. Our main outcome measures were preoperative and 1-month postoperative uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA); and rates of intraoperative complications and reoperations. We performed Cochran-Armitage trend tests. Results In 1.86 million eyes that underwent cataract surgery, the percentage of eyes undergoing phacoemulsification (PE) showed an increasing trend (p < 0.0001), from 26.8% in 2012 to 33.5% in 2018. The percentage of eyes undergoing manual small incision cataract surgery (SICS) showed a decreasing trend (p < 0.0001), from 70.0% in 2012 to 65.1% in 2018. For SICS, the percentages of eyes with good postoperative UCVA and BCVA showed increasing trends (p < 0.0001 for each), and the percentages of eyes with poor postoperative UCVA and BCVA showed decreasing trends (p < 0.0001 for each). Results for PE surgeries were mixed. For both PE and SICS rates of intraoperative complications showed a declining trend (p < 0.0001 for each) and a slight increasing trend for reoperations (PE p < 0.02; SICS p < 0.0001). Conclusions During this seven-year period there were noticeable trends in cataract surgeries performed at Aravind in terms of the mix of surgical procedures, preoperative vision, and cataract surgical outcomes.
