Is it possible to have a scratch on my cornea?

Yes - you can. Corneas can be scratched from trauma, such as with an finger nail or any foreign object. If you suspect a scratched cornea, you should be seen by an eye care professional and examined. Treatments can include topical antibiotics and even a bandage contact lens. But you should see your eye doctor to determine if you have a scratched cornea (corneal abrasion).
