The characteristics of the corneal endothelium of 134 eyes which underwent extracapsular cataract extraction and intraocular lens implantation from 1984 to 1990 were studied. We classified the initial 29 eyes as group 1 and the most recent 105 eyes as group 2. Endothelial cell loss of group 1 was much larger than that of the latter group, reflecting the degree of surgical damage. Endothelial cell of both groups decreased with index functions. The coefficient of variation of both groups showed no significant change during the observation period. The hexagonal cells of both groups decreased once after surgery, and it increased after one year in group 1, and after three months in group 2. However the late phase of the change of hexagonal cells appeared to have no relation to the degree of surgical damage. The change of hexagonal cells was supplemented by the appearance of pentagonal cells and heptagonal cells.
对1984年至1990年间接受白内障囊外摘除术和人工晶状体植入术的134只眼睛的角膜内皮特征进行了研究。我们将最初的29只眼睛归类为第1组，将最近的105只眼睛归类为第2组。第1组的内皮细胞损失比后一组大得多，反映了手术损伤的程度。两组的内皮细胞均呈指数函数减少。两组的变异系数在观察期内无显著变化。两组的六边形细胞在手术后均有一次减少，第1组在一年后增加，第2组在三个月后增加。然而，六边形细胞变化的后期似乎与手术损伤程度无关。六边形细胞的变化由五边形细胞和七边形细胞的出现补充。
