PURPOSE: This meta-analysis aimed to evaluate the outcomes of bimanual microincision cataract surgery (B-MICS) through a 1.2- to 1.5-mm incision versus standard coaxial small-incision cataract surgery (C-SICS) through a 2.8- to 3.2-mm incision. METHODS: A comprehensive literature search was performed according to the Cochrane Collaboration methodology to identify randomized controlled clinical trials comparing B-MICS with standard C-SICS. Main outcome measures were mean surgical time, mean phacoemulsification power, effective phacoemulsification time, best-corrected visual acuity, surgically induced astigmatism (SIA), mean laser flare photometry values, mean endothelial cell loss, mean increased central corneal thickness, and intraoperative and postoperative complications. RESULTS: We identified 14 randomized controlled clinical trials that included 1235 eyes diagnosed with cataracts. No statistically significant differences were detected between the 2 surgical procedures in terms of best-corrected visual acuity (p>0.05), SIA at postoperative 1 month (p = 0.09), laser flare photometry values (p = 0.38), mean endothelial cell loss (p = 0.53), increased central corneal thickness at postoperative 1 month (p = 0.64) or 3 months (p = 0.88), intraoperative complications (p = 0.68), and postoperative complications (p = 0.30); however, statistically significant differences were apparent for mean surgical time (p<0.00001), mean phacoemulsification power (p = 0.008), effective ph...
