What Is a Corneal Ulcer?

I've never actually had one myself, but I have treated many. A corneal ulcer is an open sore on the surface of the cornea. Corneal ulcers are common in contact lens wearers, especially if one sleeps in contact lenses. Most patients with them come to me in pain. If you have one, you probably know that something is wrong.

If you suspect a corneal ulcer, it's important to see your eye doctor promptly. Certain types of bacteria are extremely aggressive and can quickly cause severe damage and even blindness if left untreated.
