Eye Scratch (Corneal Abrasion), First Aid 

After assurance that there is nothing more serious than an abrasion, your doctor will most likely tightly patch the eye for a day or two after instilling an anesthetic drop and antibiotic ointment. Very tight patching is indicated for those abrasions that are felt to be essentially clean. Otherwise, patching may not be done. Your doctor may also clean and sweep (débride) the area of the abrasion to remove any possible dirty or contaminated tissue. If there is an underlying basis for the abrasion, care for this is needed to prevent recurrence. If the abrasion was contact-lens–related, you may be required to be reevaluated regarding your contact lenses as to fit and type. If the problem is recurrent erosion, your doctor will begin specific treatment for that condition.
