双泵液流系统在硬核超声乳化手术中的应用

目的探讨双泵液流系统在硬核超声乳化手术中的临床效果。方法对116例（116眼）Ⅳ～Ⅴ级硬核白内障手术中应用双泵套包系统完成超声乳化，蠕动泵模式下超声乳化，文氏泵模式下注吸，植入折叠人工晶状体。观察手术时间及术后并发症。结果双泵液流系统的应用明显缩短硬核超声乳化手术时间，手术时间3min20s～5min56s，人工晶状体植入率100％，术后角膜内皮水肿者占15％，3d内完全消退，房水闪光轻度，3d内房水清澈。结论在硬核白内障的超声乳化手术中应用双泵液流系统减少角膜内皮的热损伤，减轻硬核超声乳化术后并发症，是一种高频率、高质量的超声乳化手术的应用方法。

Double fluid pump system in phacoemulsification for hard nuclear cataract

Objective To explore the clinical efficacy of double fluid pump system in phacoemulsi- fication for hard nuclear cataract. Methods 116 eyes of 116 cases of cataract with grade ⅣorⅤ hard nu- clei were treated by phacoemulsification combined with intraoeular lens implantation under double fluid pump system. The phacoemulsifieation was performed with peristaltic pump, and irrigation and aspiration was done with Venturi pump. The operational duration and postoperative complications were observed. Results With double fluid pump system, the average operational duration was from 3min and 20s to 5min and 56s, which was shorter than the traditional phacoemulsification. The rate of intraocular lens implantation was 100%. There were 15% patients with corneal endothelial edema after the surgery, which disappeared within 3 days. The slight aqueous flare was disappeared within 3 days. Conclusion Phacoemulsifleation for hard nuclear cataract with double fluid pump system is a high-efficiency and high-quality method, which can decrease the thermal damage to the corneal endothelia and reduce postoperative complications.
