Infections of the cornea have names such as infectious keratitis, corneal ulcers, and corneal infiltrates. These infections can be due to bacteria, viruses, or parasites. Corneal infections tend to be very painful and are often characterized by a red eye, sensitivity to light, and blurred vision. Improper contact lens care or excessive contact lens wearing is often the cause of infectious keratitis. Ocular trauma can also cause these infections. Corneal ulcers are usually treated with cultures to find the offending organism along with intensive regimens of antibiotic, antiviral, or antiparasitic drops to heal the infection. Treatment times can be as short as several days to as long as several months. In some cases, the infection can be severe enough to require a corneal transplant to restore good vision.
