Performing primary posterior capsulorhexis (PPCCC) during cataract surgery is an effective prevention of secondary cataracts. It is important not to damage the anterior vitreous membrane to minimize the possible complications and adverse side effects of this step of the surgery. Most authors use a viscoelastic material to protect the anterior vitreous membrane, injected into the space between the posterior lens capsule and the vitreous membrane through a small hole in the posterior capsule. The creation of posterior capsulorhexis using 25G forceps under an implanted intraocular lens while continuously filling the anterior chamber with irrigation fluid from an irrigation cannula, without the use of a viscoelastic material is, in our opinion, a safe, fast and cheap technique of PPCCC. This technique could theoretically lead to a lower incidence of postoperative complications such as higher postoperative intraocular pressure or anterior segment inflammatory response.
在白内障手术中进行原发性后囊撕开术（PPCCC）是预防继发性白内障的有效方法。重要的是不要损伤前玻璃体膜，以尽量减少手术这一步骤可能出现的并发症和不良副作用。大多数作者使用粘弹性材料来保护前玻璃体膜，通过后囊上的小孔注入到晶状体后囊与玻璃体膜之间的间隙。在植入人工晶状体的情况下，使用25G镊子在后囊撕开，同时用冲洗套管持续向前房注入冲洗液，不使用粘弹性材料，我们认为这是一种安全、快速且廉价的PPCCC技术。从理论上讲，这种技术可能会降低术后并发症的发生率，如术后眼压升高或前段炎症反应。
