An increase in corneal thickness occurs so regularly after cataract surgery as to be considered to be the rule. It reflects the state of endothelial activity and is therefore affected both by the preoperative condition of the endothelium and the degree of surgical manipulation. The question how quickly the endothelium can be expected to recover with consequent disappearance of corneal swelling is still open to discussion. The central corneal thickness of 55 eyes with normal slit-lamp endothelial appearance undergoing cataract surgery was measured preoperatively and on the 3rd, 7th, 14th, 21st, 28th, and 42nd postoperative days. The initial corneal thickness was 0.56 mm. The greatest corneal swelling, found on the third postoperative day, was 16%. Corneal thickness returned to preoperative values in four eyes within 7 days, in 19 eyes within 14 days, in 39 eyes within 21 days, in 50 eyes within 28 days, and in all 55 eyes within 42 days. Corneal swelling, as measured on the third postoperative day, was greatest (19%) when chromic catgut was used, less (13-16%) when black silk 7/0 was used, and least (9%) when virgin silk 8/0 was used.
白内障手术后角膜厚度增加十分常见，堪称规律。它反映了内皮细胞的活性状态，因此既受术前内皮细胞状况影响，也受手术操作程度影响。内皮细胞预计多久能恢复从而使角膜肿胀消失，这一问题仍有待探讨。对55只白内障手术前裂隙灯检查显示内皮外观正常的眼睛，在术前及术后第3、7、14、21、28和42天测量中央角膜厚度。初始角膜厚度为0.56毫米。术后第3天发现的最大角膜肿胀为16%。4只眼睛在7天内角膜厚度恢复到术前值，19只眼睛在14天内恢复，39只眼睛在21天内恢复，50只眼睛在28天内恢复，所有55只眼睛在42天内恢复。术后第3天测量时，使用铬制肠线时角膜肿胀最大（19%），使用7/0黑色丝线时较小（13 - 16%），使用8/0纯丝线时最小（9%）。
