Cornea is the first coat of eye which is transparent circular structure. Functionally it acts as a lens responsible for focusing rays inside the eye. It is an important optical structure through which rays of light enter the eye. Any damage or injury to this delicate structure can lead to permanent loss of corneal transparency or in other words cause clouding and opacification.
Loss of corneal transparency prevents the entry of light rays into the eye and reduces vision. In cases of severe of damage, this can cause total loss of vision making the person visually handicapped. There are other conditions also such as malnutrition, Vitamin A deficiency, infection, certain corneal diseases such as ‘keratoconus’ and ‘corneal degeneration’, which can cause corneal blindness.
Corneal disease is third largest cause of blindness or low vision in Indian population. Corneal disorders encompass a wide spectrum of diseases most common of these are pterygium, Keratoconus, corneal dystrophy, corneal tears, corneal oedema , infective keratitis, contact lens related keratitis, allergic keratoconjunctivitis, each of these diseases need methodical approach and specialized care.
