Cataracts can affect one or both eyes and is characterized by the clouding of the lens in the eye. This can make it difficult to see clearly and if not treated in time can lead to blindness.

The cornea, in combination with the sclera, protects the eyes from various harmful microorganisms and particulate matter, including the harmful UV radiations (to some extent). The cornea is made up of three important layers, the Endothelium, Stroma, and the Epithelium.

Endothelium: The inner layer of the cornea, the endothelium helps to maintain a clear vision by removing the excess fluid absorbed by the st...more

The cornea refers to the dome-like structure visible at the front of the eye. This is the outermost layer of the eye. The cornea protects the eye against germs, dirt and other harmful particles and helps focus light coming into the eye onto the retina to create an image. It also acts as a filter against UV radiation produced by the sun. In the case of injuries to the cornea due to scarring or eye diseases a corneal transplant may be advised. This is also known as keratoplasty.

Antrior most transparent layer of the eye is called cornea. It is an extremely useful layer for refraction and protection of eye.

Any trauma, foreign body or chemical etc can invade the integrity of this layer and can be invaded by bacteria, fungus or virus, resulting in the corneal ulcer. Sometimes, due to hypoxia induced by contact lenses too can result in a corneal ulcer.

Depending on clinical presentation, a doctor diagnoses the cause of the ulcer and start the therapy. Sin...more
