Hospital-based community cataract surgery: comparison of visual outcomes between conventional extra-capsular cataract extraction and small incision cataract surgery

Abstract

the small-incision cataract surgery is gaining popularity among the ophthalmic surgeons. to compare the visual outcome of conventional extra-capsular cataract extraction (ECCE) and small-incision cataract surgery (SICS) in a hospital based community cataract program. aprospective interventional study without randomization was carried out including the patients undergoing cataract surgery by either conventional ECCE or manual SICS. They were followed up for 6 weeks postoperatively. The visual outcomes were compared between the two groups. the statistical program Epi-Info version 2000 was used to analyze the data. Mean values with standard deviations, 95% CI and p value were calculated. The p value of<0.05 was considered significant. of 85 patients, 44 (M: F=10:34) underwent ECCE and 41 (M: F=15:26) SICS (RR= 0.71, 95% CI=0.42-1.2, p value=0.16). Unaided visual acuity on the 1st postoperative day in the ECCE group was e"6/ 18 in 22.7%,<6/18-6/60 in 63.6 %,< 6/60 in 13.7%, whereas in the SICS group, the same was e"6/18 in 70.7%,<6/18-6/60 in 22 %,< 6/60 in 7.3% (95% CI= 0.23 -0.48, p=0.001). Best corrected visual acuity on the 6th week follow-up in the ECCE group was e"6/18 in 79.5%,<6/18-6/60 in 18.2 %,< 6/60 in 2.3% and in the SICS group the same was 6/18 in 90.5% and <6/18-6/60 in 4.9% (95% CI=0.44 -0.73; p=0.00 12). both ECCE and SICS are good procedures for hospital based community cataract surgery but within the 6 weeks postoperative period SICS gives better visual outcome. Remarkably higher number of female patients can be provided service in a hospital based community cataract programme as compared to males.
