Phacomorphic glaucoma is a common condition in developing countries. Extracapsular cataract extraction with a sulcus-fixated intraocular lens (IOL) is associated with increased intraoperative and postoperative complications in this condition. We developed a technique that allows a safe, controlled capsulorhexis in the presence of the shallow anterior chamber, increased anterior capsule convexity, and high intralenticular pressure seen in eyes with phacomorphic glaucoma. The intumescent cataracts are decompressed by filling the anterior chamber with viscoelastic; a 30 gauge needle is then used to aspirate liquid cortex, which facilitates a controlled capsulorhexis. This allows safe phacoemulsification of the cataract and in-the-bag IOL implantation.
晶状体膨胀性青光眼在发展中国家是一种常见病症。在这种情况下,采用沟内固定人工晶状体(IOL)的囊外白内障摘除术会增加术中及术后并发症。我们研发了一种技术,该技术能在晶状体膨胀性青光眼患者眼睛出现前房浅、前囊凸度增加及晶状体内部压力高的情况下,实现安全、可控的撕囊。通过向前房注入粘弹剂来降低膨胀性白内障的压力;然后使用30号针头抽吸液体皮质,这有助于进行可控撕囊。这使得白内障能够安全地进行超声乳化并植入囊袋内人工晶状体。
