白内障超声乳化术对角膜内皮细胞数的影响分析

目的：探讨白内障超声乳化术对角膜内皮细胞数的影响。方法：选取2008年1月-2010年12月于本院进行治疗的64例白内障患者为研究对象，将其根据手术方式分为对照组（非超声乳化小切口手术组）32例和观察组（超声乳化术组）32例，后将两组患者术前及术后3个月的角膜内皮细胞数、密度及六角形细胞比例进行统计及比较。结果：术后观察组角膜内皮细胞数、密度及六角形细胞比例均高于对照组，P均〈0．05，差异均有统计学意义。结论：白内障超声乳化术对角膜内皮细胞数的不良影响要小于非超声乳化小切口手术。

The analysis on the influence of phacoemulsification for cataract surgery for count of corneal endothelial cells

Objective： To study the influence of phacoemulsification for cataract surgery for count of corneal endothelial cells. Methods： 64 patients with cataract in our hospital from January 2008 to December 2010 were selected as research object, and they were randomly divided into control group （small incision cataract extraction without ultrasonic phacoemul- sification group） 32 cases and observation group （ultrasonic emulsification surgery group） 32 cases according the surgery methods, then the count and density of corneal endothelial cells, proportion of hexagonal cell of two groups before and after the surgery at third month were analyzed and compared. Results： The count and density of corneal endothelial cells, proportion of hexagonal cell of observation group after the surgery were all higher than those of control group, all P〈0.05, there were all significant differences. Conclusion： The harmful effects of phacoemulsification for cataract surgery for count of corneal endothelial cells is smaller than that of small incision cataract extraction without ultrasonic phacoemulsification.
