What is the healing time for a corneal ulcer?

The time until healing depends on the cause of the ulcer and its size, location, and depth. Most appropriately treated corneal ulcers should improve within two to three weeks. Treatment may continue for longer to reduce the amount of potential scarring. Corneal ulceration is a serious condition, and with inadequate or no treatment, loss of vision and blindness may occur.

Can corneal ulcers be prevented?

Preventing a corneal ulcer is important. Individuals should wear eye protection when using power tools or when they may be exposed to small particles that can enter the eye, like particles from a grinding wheel or a weed whacker.

Individuals who have dry eyes or whose eyelids do not close completely should use artificial teardrops to keep the eyes lubricated.

If an eye is red and irritated and worsens or does not respond to over-the-counter eyedrops within a day of contact an ophthalmologist promptly.

People wearing contact lenses should be extremely careful about the way they clean and wear those lenses. Corneal ulcers secondary to contact lenses are preventable. Always wash your hands before handling the lenses. Never use saliva to lubricate contact lenses because the mouth contains bacteria that can harm the cornea. Remove lenses from the eyes every evening and carefully clean them. Never use tap water to clean the lenses. Never sleep with contact lenses not designed for overnight wear in the eyes. Store the lenses in disinfecting solutions overnight. Remove lenses whenever the eyes are irritated and leave them out until there is no longer any irritation or redness. Regularly clean the contact lens case. Carefully read the instructions about contact lens care supplied by the lens maker. Consider using daily disposable lenses.
