Corneal abrasions are a small scratch on the cornea, the clear window at the front of the eye. They are generally a result of trauma (injury) to the surface of the eye. Common causes include a fingernail scratching the eye, walking into something, and getting grit in the eye, particularly if the eye is then rubbed. Injuries can also be caused by contact lens insertion and removal.
Abrasions are very painful because there are many nerves that supply the cornea.The pain gets better as your eye heals, but this can take between 24 and 48 hours.If the abrasion involves the central part of your cornea, your vision could also be temporarily affected.Apart from the pain, your eye might be watery, red and sensitive to light.
If your eye becomes increasingly red or painful after treatment or your sight becomes much more blurred, you should see an eye doctor again or contact the hospital.
Scratches to the cornea are common. The cornea could be scratched by a hairbrush, a fingernail or a tree branch. It may be scratched when a small object such as a dust particle hits your eye. If a small foreign body becomes lodged under your eyelid, this can cause scratches on your cornea.
You can self-fund or use private medical insurance to fund your treatment.
