Analysis of risk factors for posterior capsule rupture in phacoemulsification

Posterior capsule rupture (PCR) is one of the most common complications threatening postoperative vision in cataract phacoemulsification, which not only affects the surgical process such as intraocular lens implantation, but also leads to a series of intraoperative and postoperative complications. PCR is related to various factors, such as the general characteristics of the patients (shallow anterior chamber, deep anterior chamber, small pupil, specific type of cataract, cataract lens nucleus hardness, pseudo-exfoliation syndrome), surgical operators' proficiency, and various intraoperative factors. In order to fully understand PCR and reduce the incidence of clinical PCR, this article reviews the risk factors for PCR.
