Abstract Details

Purpose:

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

Setting:

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

Methods:

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.

Results:

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.

Conclusions:

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.
