What is a corneal erosion?
A corneal erosion sometimes occurs in the area of the original abrasion after the defect has healed. The erosion happens because the abrasion healed imperfectly and the cells that grew back are not tightly attached to the cornea. The cells become detatched from the cornea and an erosion occurs. Erosions can occur with little or no trauma to the eye. They often occur upon awakening. They are often as painful as the original abrasion.
