在一项前瞻性研究中，报告了37例白内障囊内摘除术患者角膜厚度和角膜内皮的镜面显微镜检查结果。中心内皮细胞损失在手术后6个月估计，发现与术后角膜中央厚度立即增加显著相关。一组术前有轻微内皮细胞营养不良的患者，术后第4天角膜厚度明显增加。术后6个月，发现这组患者角膜厚度明显增加，而其余患者已恢复到接近术前水平。此时未发现细胞损失与角膜残余厚度增加之间的相关性。术后6个月，细胞密度出现垂直差异。这种差异可能与患者的年龄有关，可能表明老年患者细胞群的再分配不完全。
In a prospective study corneal thickness and specular microscopic findings of corneal endothelium are reported in 37 patients undergoing intracapsular cataract extraction. Central endothelial cell loss was estimated six months after the operation and was found to correlate significantly to the immediate post‐operative increase in central corneal thickness. A subgroup of patients showing slight endothelial dystrophy prior to the operation showed a significantly higher increase in corneal thickness fourth day after the operation. Six months after the operation a significant residual increase in corneal thickness was found for this group, while the rest of the patients had returned to near pre‐operative levels. No correlation was found between cell loss and residual corneal thickness increase at this time. Six months after the operation a vertical difference in cell density was found. This difference could be correlated to the age of the patient, presumably indicating a less complete redistribution of the cell population in older patients.
