How long does it take for corneal epithelium to fall off and recover?

Corneal epithelial exfoliation may take 2-14 days to recover, or 1-2 months to recover. The specific time needs to be analyzed in combination with their own conditions.

Corneal epithelial cells are regenerative cells that can proliferate and repair themselves. If the patient is simple corneal epithelial exfoliation, there is no obvious basement membrane damage, and it usually recovers in about 2-3 days. However, if the patient is accompanied by infection, it is necessary to control the infection first. Corneal epithelial cells will be repaired after the infection is controlled. The process may take about 14 days. In addition, if the patient has diabetes, it may lead to poor corneal epithelial cell function, which may take 1-2 months to recover.
