Corneal ulcer is the an open sore on the surface of the cornea. This eye disease is often found in contact lens users. There are too many ways that contact lenses can injure the cornea due to its face-to-face proximity with the eyes. The cornea is the clear, dome-shaped covering over the colored part of the eye (iris). Other than protecting the eye, cornea is also responsible for refracting light that enters the eye to properly focus on the retina. If the cornea becomes inflamed due to infection or injury, an ulcer may develop.

How is a corneal ulcer treated?
NSAIDs: These medicines decrease swelling, pain, and fever. NSAIDs are available without a doctor's order. Ask your caregiver which medicine is right for you. Ask how much to take and when to take it. Take as directed. NSAIDs can cause stomach bleeding and kidney problems if not taken correctly.

Antibiotic eye medicine: This is given to treat an infection caused by bacteria. It may be in eyedrops or an ointment.

Cycloplegic eye medicine: This will dilate your pupil and relax your eye muscles, which will decrease your pain.

Pain medicines: You may be given prescription medicine to take away or decrease pain. Do not wait until the pain is severe before you take your medicine.
