Cornea
The cornea is the clear front surface of the eye. It lies directly in front of the iris and pupil, and it allows light to enter the eye for vision. But it has another very important function as well — the cornea provides approximately 65 to 75 percent of the focusing power of the eye.
The remainder of the focusing power of the eye is provided by the crystalline lens, located directly behind the pupil.
Most refractive errors — nearsightedness, farsightedness and astigmatism — are due to a less-than-optimal curvature or symmetry of the cornea.
The cornea has five layers. From front to back, these layers are:
-
The corneal epithelium.
-
Bowman's layer.
-
The corneal stroma.
-
Descemet's membrane
-
The corneal endothelium.
Problems Affecting the Cornea
Various issues can affect the health of a cornea. Some of them are:
-
Corneal Ulcer
-
Corneal Abrasion
-
Arcus senilis
-
Dry Eyes
-
Corneal Degeneration
While a few of these problems are not so severe but some of them might need a corneal transplant as they can be responsible for causing the corneal blindness in people.
