Corneal Abrasion


What is a corneal abrasion?

A corneal abrasion is a scratch on the cornea of your eye. The cornea is the clear layer that covers the front of your eye.

Eye Anatomy

What causes a corneal abrasion?

  • Contact lenses that do not fit well or are worn too long
  • A scratch or poke from a fingernail or objects such as a pencil or tree branch
  • Objects such as dirt, sand, or metal shavings that get into your eye
  • Rubbing your eyes too hard

What are the signs and symptoms of a corneal abrasion?

  • Pain
  • More tears than usual
  • Redness
  • A feeling that you have something in your eye
  • Blurred vision
  • Sensitivity to bright light
  • Headache

How is a corneal abrasion diagnosed?

Your healthcare provider will use an instrument to examine your eye. If you have something in your eye that is scratching your cornea, your healthcare provider will remove it. He or she may put dye in your eye and look at it with a lighted instrument. The light and dye can help your provider see if your cornea has been scratched.

How is a corneal abrasion treated?

You may be given antibiotic eyedrops or ointment to help prevent an eye infection. You may also be given eyedrops to decrease pain. A small scratch may heal in 1 to 2 days. Deeper or larger scratches may take longer to heal.

What can I do to care for my eyes?

  • Get regular eye exams. Get your eyes checked at least every year.
  • Eat healthy foods. Fresh fruits and vegetables that are rich in vitamins A and C may help with your vision. Foods such as sweet potatoes, apricots, and carrots are rich in good nutrients for the eyes.
  • Take care of your contacts or glasses. Store, clean, and use your contacts or glasses as directed. Replace your glasses or contact lenses as often as your healthcare provider suggests.
  • Decrease eye strain. Rest your eyes, especially after you read or sew for long periods of time. Get plenty of sleep at night. Use lights that reduce glare in your home, school, or workplace.
  • Use eyedrops safely. If your treatment plan includes eyedrops, it is important to use them as directed. Your provider may give you detailed instructions to follow. The eyedrops may also come with safety instructions. Follow all instructions to help prevent an infection. Do not touch the tip of the bottle to your eye. Germs from your eye can spread to the medicine bottle.

How can I help prevent corneal abrasions?

  • Remove your contact lenses if your eyes feel dry or irritated.
  • Wash your hands if you need to touch your eyes or your face.
  • Trim your child's fingernails so he or she cannot scratch his or her eye.
  • Wear protective eyewear when you work with chemicals, wood, dust, or metal.
  • Wear protective eyewear when you play sports.
  • Do not wear your contacts for longer than you should.
  • Do not wear colored lenses or lenses with shapes on them. These lenses may cause eye damage and vision loss.
