Abstract：
BACKGROUND: Capsulorhexis is the most important step in intumescent cataract due to the high risk of radial extension of the capsular tear during the cataract surgery. The aim of this study is to present modified the two-stage capsulorhexis technique for intumescent cataract.
METHODS: The two-stage capsulorhexis technique was used in this study. A small size capsulorhexis approximately 1.5-2 mm diameter was created in the first stage. Liquefied cortex was aspirated with a 25 G cannula to equalize anterior chamber pressure and intracapsular pressure after the small size capsulorhexis. In the second stage, a 5-6 mm capsulorhexis size was performed for a safe phacoemulsification.
RESULTS: A total of 73 consecutive patients with intumescent cataract were evaluated in this study. There were 39 male cases and 34 female cases. Mean age was 66 years ± 8 (between 53 and 84 years). A well centered complete continuous curvilinear capsulorhexis approximately 5-6 mm size was achieved in 72 of 73 cases (98.6%). Peripheral extension of capsulorhexis occurred in one eye during the second stage capsulorhexis. In this case, the capsule was cut with Vannas scissors and the capsulorhexis was completed. The rest of surgery was continued with a standard procedure and in-the-bag IOL implantation was done.
CONCLUSIONS: This technique facilitates the creation of a safe capsulorhexis compared to the one-stage capsulorhexis technique. Surgeons may consider this technique to perform a safe phacoemulsification in the intumescent cataracts.

摘要：
背景：由于白内障手术期间囊膜撕裂的放射状延伸的高风险，撕囊术是膨胀型白内障中最重要的步骤。这项研究的目的是提出改良的两阶段撕囊技术治疗膨胀型白内障。
方法：本研究采用两阶段撕囊技术。在第一阶段产生直径大约1.5-2mm的小尺寸撕囊。在小尺寸撕囊后，用25G套管抽吸液化的皮质，以平衡前房压力和囊内压力。在第二阶段,进行了5-6mm大小的撕囊手术以进行安全的超声乳化。
结果：本研究共评估了73例连续膨胀期白内障患者。男性39例，女性34例。平均年龄为66岁±8岁（53至84岁）。在73例中的72例（98.6％）中，实现了大约5-6mm大小的完整连续连续撕囊。在第二阶段撕囊期间，一只眼睛发生撕囊的外周延伸。在这种情况下,用Vannas剪刀切开胶囊并完成撕囊术。其余手术继续进行标准手术，并进行袋内人工晶状体植入。
结论：与一期撕囊技术相比，该技术有助于创建安全的撕囊。外科医生可能会考虑这种技术来在膨胀型白内障中进行安全的超声乳化术。
