改良前囊减张撕囊法在白色白内障手术中的应用

Application of modified anterior capsular reducting capsulorherxis in white cataract surgery

目的评价改良前囊减张撕囊法在白色白内障手术中的应用的效果。方法前房注入少许黏弹剂，以自制1ml注射器针头在前囊中央穿刺做一小三角形瓣口，待有液化皮质溢出于前房。经前囊穿刺瓣口往前囊下缓慢注入少许黏弹剂，并从主切口置换出遮挡术野的液化皮质，及时前房补充黏弹剂，撕囊镊完成环形撕囊操作。结果60例（68眼）白色白内障手术中，66眼顺利完成环形撕囊操作，成功率97．06％。结论在白色白内障手术中，应用改良前囊减张撕囊法，可以解决在撕囊时乳糜状皮质溢出时影响术野及前囊撕囊操作的观察问题，并减低囊袋内的压力，明显提高环形撕囊的成功率。

Objective To evaluate the efficacy of application of modified anterior capsular reducting capsulorherxis in white cataract surgery. Methods The anterior chamber was injected with a small amount of viseoelastics. A puncture small triangle flap in the center of the anterior capsule was made with self-made 1 ml syringe. Through the anterior capsule puncture flap, a small amount of viscoelasties was injected slowly under the anterior capsule, and liquefied cortex was replaced from the main incision. Curvilinear eapsulorherxis was completed with eapsulorherxis forceps. Results Sixty-eight eyes with white cataract received surgery, among them 66 eyes were successfully capsulorherxis, and the success rate was 97.06%. Conclusion Application of modified anterior capsular reducting capsulorherxis in white cataract surgery can not effect the observation of the operation field and the capsulorhexis operation, and reduce the pressure in capsular bag, improve the success rate of the annular capsulorhexis.
