The cornea is the clear front surface of the eye. It lies right in front of the iris and pupil, and it allows light to enter the eye.
Cornea is the outer layer of the eye through which the light passes into the eyes. It is a clear tissue and provides the focusing power of an image into the eyes. Corneal diseases are serious conditions since they can cause severe visual impairments like clouding, distortion, scarring and eventually blindness
There are many corneal diseases; however the major diseases are Keratoconus, Fuchs’endothelial dystrophy and Bullous Keratopathy
HOW DO I KNOW IF I HAVE CATARACTS?
CRITICAL CONDITIONS OF CORNEA
Keratoconus is a condition that weakens central corneal tissue. The cornea develops a cone-shaped deformity. The progression can be rapid in some cases, and gradual to intermittent in some cases. Keratoconus usually occurs in both eyes, but in some cases, it may occur in one eye.
Fuchs’ endothelial dystrophy
Fuchs’ endothelial dystrophy is a hereditary condition where fluid gets stick in inner layer of cornea called endothelium resulting in formation of swellings. The vision becomes cloudy and decreases. Bullous Keratopathy is a condition in which the cornea becomes permanently swollen because the endothelium is damaged and no longer exchanging fluids from inside out.
