2．2mm同轴微切口超声乳化与传统超声乳化白内障手术的对比研究

目的探讨2．2mm同轴微切口超声乳化在白内障手术中的应用价值。方法选取近两年在本院眼科接受治疗的200例白内障患者，随机将所有患者分为观察组和对照组各100例。观察组采用微切口同轴微切口超声乳化术进行治疗，对照组则采用双手微切口白内障超声乳化术进行治疗。结果两组患者在术中的有效超声乳化时间、超声能量使用和前房稳定性比较均差异无统计学意义（P〉0．05）；术后1周观察组患者的视力恢复情况、角膜内皮细胞计数及散光情况均较对照组有明显改善（P〈0．05）。结论2．2mm同轴微切口白内障超声乳化术治疗白内障，术中前房稳定性较好，术后散光小，更利于视力恢复，具有临床应用价值。

Comparative study of 2.2 mm coaxial micro incision phacoemulsification and traditional phacoemulsification in cataract operation

Objective To explore the application value of 2.2 mm coaxial microincision phacoemulsification in cataract operation. Methods 200 cases of cataract patients in the past two years in our hospital Department of Ophthalmology, all patients were randomly divided into observation group and control group with 100 cases in each. The observation group was treated with micro incision coaxial micro incision phacoemulsification for treatment, the control group with bimanual micro incision phacoemulsification for treatment. Results Two patients in the operation of the effective phaco time, ultrasonic energy use and anterior chamber stability had no significant difference （P〉0.05）; 1 weeks after operation, the patients in observation group recovery of visual acuity and astigmatism, corneal endothelial cell count were all significantly improved （P〈0.05）. Conclusion 2.2 mm coaxial microincision cataract phacoemulsificafion for cataract, intraoperative anterior chamber stability is good, postoperative astigmatism is small, more conducive to the recovery of visual acuity, has the value of clinical application.
