The amount of time it takes for the corneal abrasion to heal depends on its size. The majority of corneal abrasions heal within two to three days, whereas larger abrasions that cover more than half the cornea's surface may take four to five days to heal. Three months after an eye doctor treated a patient with traumatic corneal abrasion, 28% of the patients had recurring symptoms. With any open wound in the eye it is important to prevent infections which can significantly delay healing and increase the risk for severe complications. That is why it is always a good idea to see our optometrist for a scratched eye as soon as possible.
