The cornea is at the very front of your eye, and provides the eye with a clear outer layer. Corneal conditions can be related to:
- changes in the shape of the cornea such as astigmatism or keratoconus
- infection, such as keratitis or ocular herpes
- dystrophies that cause a change to the structures of the cornea, such as Fuch’s dystrophy or Map-dot dystrophy.
