■我们描述了一种替代的自动化技术,该技术包括通过使用连接在超声乳化装置的抽吸管上的胰岛素针对囊袋同时进行前囊穿刺和减压,以防止在膨胀期白内障撕囊期间发生“阿根廷旗标”。
■阿西斯研究所和霍夫塔尔米专业中心,位于圣保罗州,巴西。
■前瞻性介入研究。
■本研究纳入88例白色或膨胀型白内障患者的88只眼。常规透明角膜切口,用锥虫蓝染色,前房内麻醉,和眼科粘弹性装置在手术前使用。使用双公鲁尔连接器将26号针连接到超声乳化抽吸导管上进行冲洗,并通过一个新的穿刺术切口插入前房,切口斜面朝下。插入后立即,对液化皮质进行自动抽吸,以去除前豆状核材料并实现囊减压。用针尖压缩细胞核,以除去捕获在细胞核后表面和后囊之间的任何液化物质。使用相同的超声乳化和参数进行所有手术。观察并记录完全连续撕囊的速率。
■在任何情况下均未观察到并发症。一个单一的阶段,连续,并且在100%的情况下实现了中心良好的撕囊术。
■我们得出的结论是,使用连接在超声乳化机抽吸管道上的胰岛素针同时穿刺和减压囊袋有效地避免了膨胀期白内障手术中的“阿根廷国旗标志”。
UNASSIGNED: We describe an alternative automated technique that consists of simultaneous anterior capsule puncture and decompression of the capsular bag by using an insulin needle attached to the aspiration tubing of the phacoemulsification device to prevent the occurrence of the \"Argentinian Flag sign\" during capsulorhexis in intumescent cataract.
UNASSIGNED: Instituto de Olhos de Assis and Center of Specialties Hoftalmed, located in the state of São Paulo, Brazil.
UNASSIGNED: Prospective interventional study.
UNASSIGNED: Eighty-eight eyes of 88 patients with white or intumescent cataracts were included in this study. Routine clear cornea incision, capsule staining with trypan blue, intracameral anesthesia, and ophthalmic viscoelastic device were used before the procedure. A 26-gauge needle was connected to the phacoemulsification aspiration tubing using a double male Luer connector for irrigation, and aspiration was inserted into the anterior chamber through a new paracentesis incision with the bevel facing down. Immediately after insertion, automated aspiration of the liquefied cortex was performed to remove anterior intralenticular material and achieve capsular decompression. Compression of the nucleus with the needle tip was performed to remove any liquefied material trapped between the posterior surface of the nucleus and the posterior capsule. All surgeries were performed using the same phacoemulsification and parameters. The rate of complete continuous capsulorhexis was observed and noted.
UNASSIGNED: No complications were observed in any of the cases. A single-stage, continuous, and well-centered capsulorhexis was achieved in 100% of cases.
UNASSIGNED: We conclude that a simultaneous puncture and decompression of the capsular bag using an insulin needle attached to the aspiration tubing of the phacoemulsification machine effectively avoided the \"Argentinian Flag sign\" in intumescent cataract surgery.
