The cornea is the clear tissue at the front and center of the eye. Its translucency permits light to pass into the eye, through the pupil and on to the retina at the back of the eye. Its curvature focuses (refracts) the light.
Corneal eye disease is the fourth most common cause of blindness (after cataracts, glaucoma and age-related macular degeneration) and affects more than 10 million people worldwide.*
Ultraviolet light is used to promote increased cross-linking between collagen fibres within the cornea .Strengthening the cornea by cross-linking its building blocks (collagen) increases the rigidity and can arrest progression of keratoconus
and has also been reported to reverse partially the corneal steepening that has already taken place.
A cornea transplant replaces diseased or scarred corneal tissue with healthy tissue from an organ donor. There are two main types of corneal transplants: traditional, full thickness cornea transplant (also known as penetrating Keratoplasty
or PK) and back layer cornea transplant (also known as endothelial Keratoplasty, or EK).
A graft replaces central corneal tissue, damaged due to disease or eye injury, with healthy corneal tissue donated from a local eye bank. An unhealthy cornea affects your vision by scattering or distorting light and causing glare and
blurred vision. A cornea transplant may be necessary to restore your functional vision.

A thorough eye examination is carried out using the below mentioned equipment to determine if patients have any of the following disorders:
A corneal ulcer, Abscess typically occurs as a painful, red eye, with mild to severe eye discharge and reduced vision.The condition results from a localized infection of the cornea, similar....
Normally, the cornea has a dome shape, like a ball. Sometimes, however, the structure of the cornea is just not strong enough to hold this round shape and the cornea bulges outward like a cone....
Corneal dystrophies are a group of genetic, often progressive, eye disorders in which abnormal material often accumulates in the clear (transparent) outer layer of the eye (cornea)....
Bullous keratopathy is a condition in which the cornea becomes permanently swollen. This occurs because the inner layer of the cornea, the endothelium, has been damaged and is not pumping....
The changes to the cornea can make it impossible for the eye to focus without eyeglasses or contact lenses. In fact, a corneal transplant may be needed to restore vision if the condition is severe. Laser vision correction
surgery -- LASIK or PRK – can be dangerous for people with Keratoconus. Anyone with even a small degree of keratoconus should not have LASIK surgery.
Typically, an eyecare professional will treat Early stage keratoconus with contact lenses or glasses addressing the early vision correction needs of the patient. In later stages, rigid gas permeable contact lenses are
often recommended. These lenses are used to improve one's vision and to brace the bulge in the cornea. In advanced cases, where the patient can no longer achieve adequate functional vision with contact lenses, corneal
transplant surgery may be necessary.
Cross-linking is a medical procedure that combines the use of ultra-violet light and riboflavin eye drops.
Its use in Keratoconus is as first-line treatment to reduce and stop Keratoconus in the early phase of the condition, and to treat the progressive vision loss that occurs which can lead to corneal transplantation.
