白色白内障超声乳化手术撕囊方法的改进

The improvement of capsulorhexis technique in phacoemulsification for white cataract

目的探讨白色白内障超声乳化手术中一种改进的撕囊方法的应用及其效果。方法首先在前房内注满黏弹剂,用穿刺刀和囊剪在前囊上面做一个倒"T"形切口,形成两个三角形囊瓣。用注吸针头将溢出的乳糜状皮质吸出,及时补充黏弹剂,用撕囊镊夹持囊瓣的一个角,完成环形撕囊操作。结果392例白色白内障手术中,有385例顺利完成环形撕囊操作,成功率98.21%。结论白色白内障超声乳化手术中,应用这种改进的撕囊方法,可以解决在撕囊时液化呈乳糜状皮质溢出,影响前囊撕囊操作的观察和判断的问题,并降低囊袋内的压力,可以明显提高环形撕囊的成功率,因而提高手术的成功率和术后效果。

Objective To discuss the effect and application of a capsulorhexis technique used in phacoemulsification for white cataract. Methods Injected a lot of viscoelastic to fill anterior cham ber, made a reversal ＂T＂ cut in the anterior capsule and shaped two triangle capsular flaps. Used the pinhead to draw out chyleo-cortex and injected more helon,nipped a corner of flap to finish CCC. Results The retrospective study covered 392 primary cases of white cataract,in which 395 cases finished CCC （98.21%） successfully.＂ Conclusions The new improved capsulorhexis technique in phacoemulsification for white cataract can effectively solve the problem that overflowed chylo-cortex affected the process of CCC. At the same time reduced the capsule pressure and improved the success rate of CCC and phacoemulsification surgery.
