方法：选取2012-11/2014-05于本院进行超声乳化术进行治疗的60例白内障患者为研究对象，将其根据疾病情况分为A组(角膜切口组)30例和B组(角巩膜缘切口组)30例，然后将两组患者的上皮和切口修复时间、治疗前后的泪膜破裂时间、泪液分泌量、角膜染色评分及泪液相关指标进行分别统计及比较。

结果：B组的上皮和切口修复时间构成均好于A组，治疗后1，7，14，28d的泪膜破裂时间、泪液分泌量、角膜染色评分及泪液相关指标也显著地好于A组，均P<0.05，两组上述比较指标有显著性差异。

结论：角巩膜缘切口在超声乳化术中的应用价值相对更高，对患者的不良影响更小且术后综合状态恢复更快。

METHODS: Sixty patients with cataract who were treated with phacoemulsification in our hospital from November 2012 to May 2014 were selected as research object, and they were divided into group A(corneal incision group)30 cases and group B(corneoscleral rim incision group)30 cases according to the disease state. Epithelial and incision repair time, tear break-up time, tear secretion, corneal staining score and tear related indexes before and after the treatment of two groups were respectively analyzed and compared.

RESULTS: The epithelial and incision repair time constitution of group B were better than those of group A, the incision repair time, tear break-up time, tear secretion, corneal staining score and tear related indexes at 1,7, 14 and 28d after the treatment were all significantly better than those of group A too, there were all significant differences(all P<0.05).

CONCLUSION: The application value of corneoscleral rim incision in the patients with cataract phacoemulsification is relatively higher,and bad influence of this method for the patients is smaller, the postoperative recovery of comprehensive state are faster.
