A corneal abrasion occurs when there is a loss of cells from the epithelium or surface of the cornea.
A corneal abrasion heals by the movement of neighboring epithelial cells, which slide over the wounded area, and through a cell division process called mitosis, which fill in the abraded area with new epithelial cells.
