Performing capsulorhexis in white intumescent cataracts during phacoemulsification surgery is challenging for cataract surgeons because of high intralenticular pressure and reduced red reflex. Capsulorhexis extension to the periphery of the lens is a common occurrence due to lens intumescence. We used a vitrectomy cutter to create an initial tear in the anterior capsule and simultaneously remove a part of milky fluid coming out of the intumescent lens. Once the lens was decompressed, capsulorhexis was completed using capsulorhexis forceps. This technique helped in controlling capsulorhexis in eyes with intumescent cataracts by reducing the intralenticular pressure and thereby preventing unexpected radial capsular tear.
在白内障超声乳化手术中，对白色膨胀性白内障行撕囊是对白内障医生的一个挑战，因为此时眼内压高且红光反射减弱。由于晶状体膨胀，撕囊常扩展至晶状体周边。我们使用玻璃体切割器在前囊上制造一个初始撕裂口，同时清除部分从膨胀晶状体中冒出的乳白色液体。晶状体一旦减压，就用撕囊镊完成撕囊。该技术通过降低眼内压，有助于控制膨胀性白内障眼中的撕囊，从而防止意外的放射状囊膜撕裂。
