Bimanual Microincision Cataract Surgery versus Coaxial Microincision Cataract Surgery: A Meta-Analysis of Randomized Controlled Trials and Cohort Studies

Purpose. this meta-analysis was conducted to compare the intraoperative and postoperative outcomes of bimanual microincision cataract surgery (b-mics) and coaxial microincision cataract surgery (c-mics). methods. three databases were searched for papers that compared b-mics and c-mics from inception to june 2016. the following intraoperative and postoperative outcomes were included in the final meta-analysis: ultrasound time (ust),effective phacoemulsification time (ept),balanced salt solution use (bss use),mean surgery time,best-corrected visual acuity (bcva),central corneal thickness (cct),and increased cct. results. there were no statistically significant differences in mean surgery time,ust,bss use,bcva,cct,or increased cct (one subgroup at postoperative day 7-8 and another subgroup at postoperative day 30). however,there was less ept needed during surgery (p<0.01) and lower levels of increased cct at postoperative day 1 (p=0.02) in the b-mics group compared with the c-mics group. conclusions. the ept was shorter and increased cct was less at postoperative day 1 in the b-mics group. there were no statistically significant differences in other intraoperative and postoperative outcomes between the b-mics group and the c-mics group. b-mics is an efficient and safe cataract surgery procedure. © 2017 chenxi fu et al.
