Eyesight depends on a complex series of interactions between the different parts of the eye. The cornea is the clear covering of the front of the eye. The basic definition of keratitis is any inflammation of the cornea of the eye.

As a general rule, the deeper the corneal infection is, the more severe the symptoms and complications. that corneal infections, although relatively infrequent, are the most serious complication of contact lens wear to correct refractive errors.

Keratitis can be caused by a number of things from infections to injuries. Sometimes the cornea is damaged after a foreign object has penetrated the tissue, such as from a poke in the eye. At other times, bacteria or fungi from a contaminated contact lens can pass into the cornea. These infections can reduce visual clarity, produce corneal discharges and perhaps erode the cornea. Corneal infections can also lead to corneal scarring, which can impair vision and may require a corneal transplant.

Minor corneal infections are commonly treated with anti-bacterial eye drops. If the problem is severe, it may require more intensive antibiotic or anti-fungal treatment to eliminate the infection, as well as steroid eye drops to reduce inflammation. Frequent visits to an eye care professional may be necessary for several months to eliminate the problem.
