The cornea is the window to the human eye and therefore our window to the world through our most important sense. A cornea specialist is an ophthalmologist who has fellowship training in corneal transplant techniques and other means of managing corneal diseases. The cornea has three main layers and each part can become affected by different infections, diseases, external insults, and even cancer. These can result in scarring of the cornea, irregularity in shape, and inflammation that can result in blurred vision, pain, and blindness and can require treatment by our cornea specialists in Fresno.
Injured or diseased corneas can become cloudy, resulting in impaired vision. Depending on the severity of the impairment, treatments ranging from using specialized contact lenses to surgery may be needed to improve a patient’s sight. Even though most cornea infections or injuries heal themselves without medical treatment, you may experience certain symptoms during the healing process. These symptoms include:
Extreme light sensitivity
Some corneal conditions do require treatment. Our board-certified eye surgeons and optometrists at Eye Medical Center of Fresno perform various corneal procedures such as:
Our eye doctors use this procedure, also called corneal collagen cross-linking or CXL, to halt bulging of the eye’s surface for patients diagnosed with keratoconus. Keratoconus is a progressive eye disease in which the normally round cornea thins and begins to bulge into a cone-like shape. Cross-linking is a minimally invasive alternative to cornea transplants.
Cross-linking isn’t necessary for keratoconus patients whose symptoms are mild. In those case, vision can be corrected with eyeglasses or customized soft contact lenses.
A corneal transplant involves removing the central area of a patient’s cornea and replacing it with a donor’s cornea or an artificial cornea. A transplant may be recommended to treat keratoconus, but it’s also used for patients with scarring on the cornea caused by injury or infection and patients experiencing loss of vision due to cloudy corneas. Different transplant techniques are used to address specific conditions.
Several cornea transplant techniques exist. The specific technique used can be based on the whether your issues occur at the back part or front part of the cornea. These transplant procedures remove only the diseased tissue and provide faster healing, require fewer activity restrictions, and reduce the risk of later injury to the eye.
A full-thickness transplant procedure, called penetrating keratoplasty, involves removing the central two-thirds of the damaged cornea. The full visual recovery can take up to a year and patients must be careful to avoid injuring the eye for the rest of their lives.
