The cornea is the very front surface of the eye, acting like the "window" of the eye. The cornea plays a major role in how you focus on images. In conjunction with your natural crystalline lens the cornea helps to provide required focusing power. If the cornea becomes weak or damaged serious visual problems may arise. Because the cornea is such an important part of your visual system, please make sure to contact the ophthalmologists of the Omaha Eye & Laser Institute if you think you might have damaged your cornea. Treating damaged or irregular corneas is something that is routinely done at our eye care office. Each damaged cornea requires special attention by our eye doctors. Typically we can start treating the cornea with medication. If your vision cannot be accurately corrected with medications, a corneal transplant may be required.
Your cornea is the clear tissue in front of your iris and pupil. Although it is completely clear, it actually has three layers. The cornea does not have blood vessels, relying on tears and the fluid behind your eye for nourishment.This is because the cornea needs to be completely clear for the best vision. When the cornea is damaged, obstructed or misshapen, this can affect vision. A misshapen cornea is a very common condition, and can affect vision in many ways. Common conditions such as myopia or astigmatism, in which the cornea is misshapen, can be corrected with glasses and contacts, and even laser surgery.
How does damage to the cornea occur?
Damage to the cornea may arise from various reasons such hereditary issues, chemical burns, blunt object trauma, viruses or bacteria. Conditions that may require a patient seek a cornea transplant involve, clouding of the cornea, keratoconus, fuchs dystrophy, irregular corneal surface tissue growths, or corneal swelling.
Can cornea problems be prevented?
Corneal infections caused by bacteria and viruses can be prevented by good hygiene and limiting contact with those who have contagious forms of conjunctivitis. Do not share eye makeup, contact lens cases, contact lens solution, and eye drops with people who are infected. Follow strict guidelines for contact lens hygiene to decrease the risk of corneal infections. Corneal disease resulting from hereditary factors, like dystrophies, cannot be prevented, but vision can be preserved with early detection.
