What is it?

Keratitis is a condition in which the eye's cornea becomes inflamed. The cornea is the clear part on the front surface of the eye. Keratitis is quite common, and wearing contact lenses increases the risk of it. Keratitis can be caused due to a virus, bacteria, fungi, parasite infection, or injury to the eye. Wearing contact lenses for an extended time, sleeping with contact lenses, or swimming with contact lenses can also cause keratitis.

Signs & symptoms

Symptoms of keratitis include:
- Red coloration of the eye
- Eye discharge and excessive tearing
- Pain and irritation
- Vision blurriness
- Sensitivity to light
- Difficulty in opening the eye


Keratitis can be detected during an eye exam performed by an ophthalmologist. During the exam, the physician will assess both eyes and may use a slit lamp. A slit lamp magnifies the structures in the eye, thus helping the physician examine it.


Treatment of keratitis depends on the cause of it. Viral infections will be treated with antiviral medicine, and a bacterial infection will be treated with antibiotics, etc. In some cases, no treatment is required. If left untreated, keratitis can cause complications such as scarring, chronic inflammation, and vision problems. In severe cases, a cornea transplant may be required.
