When the corneal epithelium is disconnected from the corneal layer under it, it is painful and causes blurry vision and dry eyes. If the epithelium is not well adhered, opening the eyelids could detach the epithelium. The cornea has many nerve cells, which is why they are so painful. You are at higher risk of corneal erosion: a) have very dry eyes b) have had a corneal abrasion or other eye injury c) have had corneal disease (such as corneal dystrophy) d) wear contact lenses that were not fitted properly e) wear contact lenses that have not been well cared for.

Treatment: Artificial tears and lubricating ointment, if it does not work, oral tetracycline or topical prednisolone, or both, and excimer laser ablation can be effective treatments for recurrent cases.
