方法：试验组：选取小梁切除术后需行超声乳化白内障手术的白内障患者30例32眼，对照组：随机选取单纯老年性白内障患者36例40眼，由同一熟练眼科医师行白内障超声乳化术。用非接触式角膜内皮显微镜对患者分别于术前及术后7d； 1，3，6mo拍摄中央、鼻侧、颞侧、上方及下方共五方位角膜内皮细胞图像，并对图像自动分析。

结果：在白内障手术中试验组五方位角膜内皮细胞均比对照组易受到损伤(P<0.01)。

结论：抗青光眼术后白内障患者角膜内皮细胞对超声乳化白内障吸除术产生的损伤更加敏感，所以术前评估、手术操作及术后处理很重要。

METHODS: Patients with cataract after anti-glaucoma surgery were selected, and the surgery of phacoemulsification was performed by a same skilled surgeon, The superior, inferior, central, nasal, temporal endothelium cells were observed with a non-contact endothelium scope on pre-operation and seventh day, first month, third month and sixth month of post-operation.

RESULTS: After operation, there were obvious differences of corneal endothelium of every sites between two groups(P<0.01).

CONCLUSION: Endothelium cells of senile cataract in patients after anti-glaucoma surgery are easier to be damaged in the phacoemulsification, so preoperative evaluation, surgery manner and postoperative treatment are very important.
