【摘要】 目的:探討白色白內障超聲乳化手術的撕囊方法。方法:對76例76只眼,應用一種手法撕囊。向前房內注入黏彈劑,在上方用截囊針截開晶狀體前囊約2 mm,用囊膜剪在晶狀體前囊截囊口兩端呈鈍角剪開前囊膜約2~3 mm,再用撕囊鑷夾持前囊右側角逆時針完成撕囊。結果:76只眼白色白內障應用此方法環形撕囊均獲成功,成功率為100%,超聲乳化手術順利完成。結論:在白色白內障超聲乳化手術中,應用截囊聯合剪切撕囊簡便、安全、有效,其可顯著提高白色白內障連續環形撕囊的成功率,便于掌握和應用。

Use of Capculorhexis Technique for Phacoemulsification in White Cataract/WU Hong, ZHANG Yu, YAN Xiao-ran, et al.//Medical Innovation of China,2014,11(28):120-122
【Abstract】 Objective: To find a way of capculorhexis in phacoemulsification for patients with white cataract. Method: Phacoemulsification was performed in seventy-six eyes of 76 patients with white cataract using a capculorhexis technique. Viscoelastic was injected to fill anterior chamber. Firstly, a cut was made on the anterior capsule about 2 mm length using discission needle. Cutting two sides of the anterior capsule opened in an obtuse angle with scissors and the continuous curvilinear capsulorhexis (CCC) was finished. Result: All cases with white cataract had successful results of CCC (100%). Conclusion: In the white cataract phacoemulsification the use of combinational capculorhexis technique is an easy, safe and effective method. It significantly improves the success rate of CCC. And it is easy to handle and extend.

白內障超聲乳化手術相對于傳統的白內障囊外摘除術而言,具有手術切口小、組織損傷輕、安全性好、恢復快、無需等待白內障成熟才施行手術等優點在臨床得到廣泛開展。而連續環形撕囊術是手術順利完成的關鍵步驟之一[1]。隨著我國人口老齡化進程加快,白內障患者不斷增多,其中白色白內障患者占有相當比例。白色白內障是指晶狀體皮質白色混濁或晶狀體核硬化混濁,在手術顯微鏡下缺乏眼底紅光反射,以致難以區分晶狀體前囊膜和皮質的白內障[2]。由于眼底紅光反射缺失,前囊膜與其下方皮質的對比度差,撕囊過程中不易辨認撕囊軌跡,易向周邊部撕裂而不易被發現,導致撕囊失敗,影響后續手術操作[1]。為解決白色白內障撕囊困難的難題,在白色白內障超聲乳化手術中,筆者應用截囊聯合剪切兩側囊膜再撕囊的方法,顯著提高了白色白內障連續環形撕囊的成功率,取得了滿意的效果。……
