A corneal abrasion is a scratch on the eye's cornea. The cornea is the clear, protective lens that is in front of the iris, which is the colored part of the eye, and the pupil -- the black circle in the middle of the eye. It is caused due to various reasons such as a foreign body, fingernails, branches of leaves, makeup material, paper pieces etc.
HOW IS CORNEAL ABRASION DIAGNOSED?
An ophthalmologist diagnoses corneal abrasion by the following:
1. A slit lamp examination
2. Ocular CT Scan
3. MRI scan in extreme cases
HOW IS CORNEAL ABRASION TREATED?
Antibiotic eye drops or ointment may be prescribed or placed in your eye or eyes. Some ophthalmologists may use steroid or nonsteroidal anti-inflammatory eye drops to reduce inflammation and to avoid potential scarring.
Eye drops to stop eye muscle spasm may be placed into your eyes by your ophthalmologist. These drops may relieve your pain and your sensitivity to light, but they may also cause blurring of vision.
The eye may or may not be patched by your ophthalmologist. Recent evidence shows that patching the eye probably does not help and may actually have a negative impact on the healing process. Whichever choice your ophthalmologist makes, it is not likely to be a significant issue. Your ophthalmologist may have specific reasons for your treatment based on the specific circumstances of your case. If you are in doubt about the ophthalmologist's decision, ask him or her why a certain choice has been made. If there is any evidence of rusty metallic deposits within the injured cornea, your ophthalmologist may recommend a tetanus vaccination if your immunization status is not up to date.
Although anaesthetic eye drops may be used to immediately relieve the eye pain at the time of your examination, these drops cannot be prescribed for you to use at home because they interfere with the natural healing process.

Wearing of contact lenses should be avoided till the corneal abrasion heals.
