It serves as a physical barrier against dust, microorganisms and other harmful particles. The cornea also plays an important role in vision. It filters some amount of ultraviolet light and protects iris, pupil and anterior chamber. As light is refracted by the curvature of the cornea, it is focused on the object and forms a clear Image. Any infection, disease or trauma to the cornea can interfere with vision by blocking or distorting light as it enters the eye. It contains specialized tissue having no blood vessels and is nourished with your tears and aqueous humor (behind the cornea). Cornea is made up of three major components. Epithelium – Cornea has numerous nerve endings, that’s why you experience pain while rubbing your eyes. It absorbs oxygen and nutrients from the tears. Epithelium is connected with stroma with the help of basement membrane. Stroma – The stroma is the thickest part of the cornea and is made up of collagen and water. Collagen fives elasticity and keeps cornea firm. These collagen fibres are arranged in strictly in a regular, geometric fashion. This arrangement is responsible for clear cornea, while in case of trauma, collagen fibres laid down in repair, often leads to cloudy cornea. Below stroma is the Descemet’s membrane, which connects it with endothelium.

2. Endothelium - The innermost layer of the cornea is made up of endothelium. Function of endothelium is to maintain fluid balance by acting as a pump, expelling excess water as it is absorbed into the stroma. Without this specialized function, the stroma could become waterlogged and hazy and opaque in appearance, also reducing vision. Symptoms of corneal conditions Minor injuries of cornea heal by itself while major injuries may result in scarring and impaired vision. Intense pain. Blurred vision. Double vision Tearing. Redness. Extreme sensitivity to light. Corneal conditions Injuries/Trauma Eye allergies Keratitis. Ocular herpes Herpes zoster (shingles) Dry eye. Nutritional Deficiencies like Vitamin A Corneal dystrophies – Keratoconus, Map-dot-fingerprint dystrophy, Fuch's dystrophy

3. Common diseases that can affect the cornea — Abnormal growths, autoimmune diseases, Stevens - Johnson syndrome, iridocorneal endothelial syndrome and pterygium. Treatment Treatment Simple corneal conditions can be treated with antibiotic or anti-inflammatory eye drops or pills. If you have advanced corneal disease, you may need an advanced treatment. Laser treatment – In Corneal dystrophies, doctors can use a type of laser treatment called phototherapeutic keratectomy (PTK) to reshape the cornea, remove scar tissue, and make vision clearer. Corneal transplant surgery – In case cornea is damaged and cannot be repaired, doctors can remove the damaged part and replace it with healthy corneal tissue from a donor. Artificial cornea - As an alternative to corneal transplant, doctors can replace a damaged cornea with an artificial cornea, called a keratoprosthesis (KPro).
