Postoperative capsular bag distension syndrome (CBDS) is a rare complication of cataract surgery which might occur in the early postoperative period, as well as several years after uncomplicated surgery. The aim of this study was to review the current evidence on postoperative capsular bag distension syndrome. PubMed and Web of Science were used for literature search. The typical presentation involves deterioration in visual acuity, unexpected myopic shift or less frequently hyperopia. In eyes with clear capsular fluid and no posterior capsule opacification, usually in the late postoperative period, CBDS can be asymptomatic. Risk factors for developing CBDS include retained ophthalmic viscoelastic device, inadequate subincisional cortex cleaning, apposition between the intraocular lens (IOL) and the capsular bag, postoperative inflammation and IOL sequestration with . Visualization of the CBDS can be aided with Scheimpflug imaging, ultrasound biomicroscopy, and particularly anterior-segment optical coherence tomography. Nd:YAG posterior capsulotomy, and in some cases anterior capsulotomy, is accepted as a standard and effective CBDS treatment. Surgical approach could be beneficial in cases suspected of presence or when it is impossible to perform Nd:YAG posterior capsulotomy.
术后囊袋扩张综合征（CBDS）是白内障手术的一种罕见并发症，可能发生在术后早期，也可能在无并发症手术后数年出现。本研究的目的是综述目前关于术后囊袋扩张综合征的证据。使用PubMed和科学网进行文献检索。典型表现包括视力下降、意外的近视性移位，较少见的是远视。在囊袋内液体清澈且无后囊膜混浊的眼中，通常在术后晚期，CBDS可能无症状。发生CBDS的危险因素包括残留眼科粘弹剂、切口下皮质清理不充分、人工晶状体（IOL）与囊袋之间的贴附、术后炎症以及IOL隔离。Scheimpflug成像、超声生物显微镜检查，尤其是前段光学相干断层扫描有助于观察CBDS。Nd:YAG后囊膜切开术，在某些情况下还有前囊膜切开术，被认为是标准且有效的CBDS治疗方法。在怀疑存在或无法进行Nd:YAG后囊膜切开术的情况下，手术方法可能有益。
