方法：选取于2013-08/2016-03来我院眼科就诊的白内障患者140例152眼，均行小切口非超声乳化白内障摘除术，于术前和术后1wk，1、3mo测量所有患者角膜上部、中央区和下部的角膜内皮细胞计数，计算并比较所有患者角膜内皮细胞的六边形细胞比例、密度、丢失率、角膜内皮细胞面积。

结果：术后36眼有后弹力层褶皱、房水闪辉，治疗后消失。术后可见患者角膜上部切口有较轻的角膜水肿，未见其他并发症。共有患者128例137眼完成了共计3mo的随访，失访12例15眼。角膜上部、角膜中央区、角膜下部术后1wk， 1、3mo角膜内皮细胞密度三组组间差异有统计学意义(F=3.526，P=0.031)，各时间点差异有统计学意义(F=4.111，P=0.018)。术后1wk，1、3mo角膜内皮细胞丢失率三组组间差异有统计学意义(F=3.526，P=0.031)，时间点差异有统计学意义(F=4.111，P=0.018)。术后1wk， 1、3mo角膜内皮细胞六边形细胞比率三组组间差异有统计学意义(F=4.348，P=0.014)，时间点差异有统计学意义(F=4.964，P=0.008)。术后1wk，1、3mo角膜内皮细胞面积三组组间差异有统计学意义(F=3.180，P=0.044)，时间点差异有统计学意义(F=3.511，P=0.032)。

结论：小切口非超声乳化白内障摘除术后角膜内皮细胞密度降低，六边形细胞比例下降、角膜细胞面积扩大。

METHODS: Totally 140 cataract patients(152 eyes)treated in our hospital from August 2013 to March 2016 were selected. All of the patients underwent small incision non-phacoemulsification cataract surgery. Before surgery and at 1wk, 1mo and 3mo after surgery, we measured the corneal endothelium of upper cornea, the central cornea and the lower part of cornea. The proportion and density of hexagonal cells, loss rate and cell area in corneal endothelial cells were calculated and compared.

RESULTS: Postoperatively 36 eyes had posterior elastic layer folds, aqueous flare, which disappeared after treatment. After surgery, corneal incision was found to have mild corneal edema. No other complications were found. A total of 128 patients(137 eyes)were followed up for a total of up to 3mo, with a loss of follow-up in 12 patients(15 eyes). After surgery, corneal endothelial cell density of the upper part of the cornea, the central cornea and the lower part of cornea, was statistically significantly different with each other(F=3.526, P=0.031), the difference in different time points was statistically significant(F=4.111, P=0.018). The postoperative corneal endothelial cell loss rate was statistically significant different between the three groups(F=3.526, P=0.031), at different time pionts(F=4.111, P=0.018). There was statistical significance of percentage of hexagonal cells between the three groups(F=4.348, P=0.014), the difference was significantly different between different time points(F=4.964, P=0.008). There was statistical significance of corneal endothelial cell area between the three groups(F=3.180, P=0.044), the difference was significantly different between the time points(F=3.511, P=0.032).

CONCLUSION: After small incision non-phacoemulsification cataract surgery, corneal endothelial cell density decreased, hexagonal cell proportion decreased, corneal cell area expanded.
