    Cornea is the transparent outermost layer of the human eye. Technically speaking, the cornea is not a single layer; it’s made of five delicate membranes that are arranged one below the other. Cornea plays a major role in focussing your vision; its transparency and its curvy shape helps in refracting light from an object in a way that it falls at the perfect spot on the retina thereby enabling sharpness of vision. In addition to this, the cornea also acts as a protective layer preventing all the dust, dirt and germs from entering into the inside of our eyes. Now, that’s quite an important role to play, ain’t it? Corneal Problems - What could go wrong here? The corneal surface and its structure are very delicate. Any injury or infection of the cornea can lead to damage leading to loss of corneal transparency and thereby disrupting the normal vision. Common problems that affect the cornea include, corneal ulcers, keratitis (inflammation of the cornea) and keratoconus (thinning of the cornea) apart from the allergies, infections like herpes and the corneal abrasions caused by external injuries. Common symptoms produced are: Pain Reduced Vision Inability to open eyes in bright light Redness Watering Swelling of the eyelid Did you know? The cornea has no blood vessels within it. It gets all its nourishment from your tears and a fluid called the aqueous humor that’s filled behind the cornea. Corneal Treatment - What are the options? Corneal Diseases require multi-modality of medications which help in reducing the symptoms and curing the disease. Also these diseases take a very long duration of treatment and frequent follow-ups. The most important factor for early healing and recovery is patient’s compliance to use medications religiously as per the instructions. In cases of infections of cornea, small amounts of superficial corneal tissue is removed (scrapping) and evaluated for presence of type of infection and the organism causing it. Depending on the results, specific medications for that infection are given to help faster recovery.
