The cornea is the transparent portion of the eye . Along with the sclera, it is part of the wall of the eyeball. The cornea’s most important function is vision. When light enters the eye, it is refracted or bent by the cornea. The cornea consists of 3 main layers, the epithelium, the stroma, and the endothelium. Any disease or infection of the cornea will affect the vision and can also cause pain, discomfort. Some scars on the cornea are permanent.

Transparency and integrity of the cornea is the most important factor in maintaining good vision, and is crucial to visual acuity, clarity, as well as comfort of the eyes. A cornea can be damaged by disease, infection or injury. Keratoconus is an example of reduced integrity of the structure of cornea, and affects the young. Early diagnosis, monitoring and control of progression with RGP contact lenses or collagen cross-linking is the key to preserve good vision. The epithelium is frequently affected by infection, erosion or allergies.The other cause of damage could be dry eyes or even foreign body that enters the eye. Some symptoms of cornea problems include, pain, blurred vision, tearing, redness and extreme sensitivity to light.
