方法：回顾性分析52眼带有Ⅲ级以上硬核的复杂性白内障患者，采取晶状体超声粉碎技术(A组)以及小切口白内障囊外摘除(B组)不同术式的治疗效果。

结果：A组术后最佳矫正视力的提高优于B组，差异有统计学意义(P<0.05)； 两种手术方式对中央角膜厚度的影响，差异无统计学意义(P>0.05)； A组手术中对角膜内皮的影响多于B组，差异有统计学意义(P<0.05)； A组手术并发症的发生低于B组，差异有统计学意义(P<0.05)。

结论：对于治疗带有Ⅲ级以上硬核的复杂性白内障，超声粉碎晶状体技术可以考虑应用。

METHODS:Totally 52 eyes were performed retrospective analysis with phacofragmentation technique(group A)and extracapsular extraction surgery for cataract with small incision(group B)differently, and the effects of surgical treatment were compared.

RESULTS:Postoperative best corrected visual acuity(BCVA)of group A lens was better improved than group B, the difference was statistically significant(P<0.05); the difference of corneal thickness was not statistically significant(P>0.05); the effect of group A on corneal endothelium was larger than group B, the difference was statistically significant(P <0.05); the surgical complications of group A were lower than group B, the difference was statistically significant(P <0.05).

CONCLUSION: The technology of sonicating lens can be considered for the cataract of the grade Ⅲ nuclear and above.
