Various disorders can affect the cornea, which helps protect and focus the eye.
What are corneal disorders?
Your cornea is the outermost layer of your eye. It is clear and shaped like a dome. The cornea helps to shield the rest of the eye from germs, dust and other harmful matter. It also helps your eye to focus. If you wear contact lenses, they float on top of your corneas.
Problems with the cornea include:
- Refractive errors
- Dystrophies — conditions in which parts of the cornea lose clarity due to a buildup of cloudy material
