Objective: To compare the therapeutic effects and operation time of 23-G vitrectomy and conventional 20-G vitrectomy on complications (retinal breaks, retinal detachment). Methods: Related studies published prior to October 2014 were retrieved via exhaustive searching of English and Chinese scientific literature databases. High quality clinical cohort studies, focused on 23-G and 20-G vitrectomy in retinal diseases, were carefully selected according to our study inclusion criteria. Statistical analyses were also conducted by comprehensive Meta-analysis 2.0 (CMA 2.0) software. Results: Fifty-five published articles (47 in English and 8 in Chinese) were initially identified as relevant to our keyword search, of which 10 studies were included in this meta-analysis, including 1464 patients treated for retinal diseases (718 treated with 23-G vitrectomy, 746 treated with 20-G vitrectomy). Our meta-analysis showed that the incidence of retinal breaks in 23-G vitrectomy were lower than those in 20-G vitrectomy (P = 0.017). However, no such difference was found in the incidence of retinal detachment between these two surgical procedures (P = 0.467). As for operation time, our results showed that 23-G vitrectomy procedure was performed in less time compared with patients receiving 20-G vitrectomy (P < 0.001). Conclusions: The 23-G transconjunctival sutureless vitrectomy may be superior to conventional 20-G vitrectomy in reducing the incidence of retinal breaks and shortening operation time.
