Our eye is called as the camera of our human body whereas the cornea would be the glass at the front of the camera lens.

TYPES OF DISEASES

• Keratoconus is a weakening and thinning of the central cornea. The cornea develops a cone-shaped deformity
• Fuchs' endothelial dystrophy is a hereditary abnormality of the inner cell layer of the cornea called the endothelium.
• Bullous keratopathy 

LASIK ( laser in situ keratomileuses) is a procedure in which a laser is used to reshape your cornea — the clear, round dome at the front of your eye to improve the way your eye focuses light rays onto your retina. To see clearly, the cornea and the lens must bend or refract light rays so that they focus on the retina. The retina converts the light rays into impulses that are sent to the brain, where they are recognized as images. If the light rays don’t focus on the retina, the image you see is blurry. This is called a refractive error. Glasses, contact lenses, and refractive surgery try to reduce these errors by making light rays focus on the retina.
