What is corneal abrasion?


A corneal abrasion is an injury to the very front of the eye called the corneal epithelium.  Abrasions are painful.  Common causes of corneal abrasions include fingernails, paper cuts, tree limbs or rubbing of the eye.  Contact lenses may also cause abrasions that become infected quickly.  It is best to see an ophthalmologist if you think you have an abrasion.
