Abstract: Objective To evaluate the effect of anterior chamber support on posterior capsular rupture in cataract surgery. Methods A total of 22 cases(22 eyes)with posterior capsular rupture during cataract surgeries that were performed between January 2014 and December 2016 were retrospectively evaluated. An anterior chamber maintainer(ACM)was used to facilitate the extraction of residual lens cortex. The following clinical parameters were recorded preoperatively and after one and seven days post-operatively: the best corrected visual acuity(BCVA), intraocular pressure(IOP), corneal edema, inflammation of the anterior chamber, and complications. Results The patients post-operative BCVA significantly improved relative to the pre-operative BCVA. Normal IOP, mild corneal edema, and mild inflammation of the anterior chamber were reported. No severe complications were found during or after surgery. Conclusion Application of ACM in cases of posterior capsular rupture during cataract surgery may stabilize the anterior chamber, alleviate vitreous disturbance, prevent expansion of posterior capsular rupture, and facilitate the extraction of residual lens cortex.
