Abstract Details


To compare change of corneal epithelial thickness and stromal thickness after cataract surgery and to investigate difference of remodeling trend of corneal epithelium and stroma


Wonju Severance Christian Hospital, Wonju-si, Gangwon-do, South Korea


This study compared topographic values of corneal epithelial thickness (CET) and stromal thickness (ST) in 40 eyes underwent cataract surgery. Epithelial thickness mapping was obtained using a spectral-domain optical coherence tomography before surgery, 3 days, 7 days and 1 month after surgery.


The mean preoperative CET of center (2 mm in diameter), paracenter (2-5 mm), mid-periphery (5-6 mm) were 52.13�Â�±3.41�Â�µm, 50.42�Â�±2.97�Â�µm and 49.12�Â�±3.05 �Â�µm. CET of center changed to 51.54�Â�±4.59�Â�µm at 3 days, 52.93�Â�±4.78�Â�µm at 7 days, 51.03�Â�±3.63�Â�µm at 1 month postoperatively. Comparing to preoperative values, CET was significantly different only at 1 month postoperatively in paracenter and mid-periphery zone. But ST was significantly different from 3 days to 1 month postoperatively in central 6 mm diameter zone.


Topographic remodeling patterns are different between corneal epithelium and stroma after cataract surgery. Corneal stromal thickness increased just after surgery, but compensative change of corneal epithelium started between 7 days and 1 month after cataract surgery.
