Keratoconus, often summarized to “KC”, is an unprovocative eye disorder in which the naturally round dome-shaped cornea gradually thins causing a cone-like protrusion to grow. This results in remarkable impairment of vision.
Who experiences Keratoconus?
The cornea of the eye is responsible for refracting most of the light coming into the eye. And is the clear window of the eye. Simple tasks, like reading a book, watching TV or driving seem difficult and critically affect the way we look at the world because of the abnormalities of the cornea.
Increased sensitivity to light and slight blurring and distortion of vision is caused due to keratoconus in the early stages. These symptoms are normally seen in early twenties and the late teens. Keratoconus may stabilize or slow down after progressing for about ten to twenty years.
Causes of keratoconus:
The accurate cause of keratoconus is unspecified. There are many thesis based on study and its connection with other disorders such as genetic causes and allergies however, no one thesis describes it all and it may be caused by a fusion of things.
Treatment for Keratoconus:
In the prior stages, soft contact lenses and eyeglasses may be used to correct the moderate astigmatism and nearsightedness triggered in the early stages of keratoconus. Rigid gas permeable (RGP) contact lenses are generally prescribed to correct vision more adequately, as the disorder progresses and the cornea continues to thin and change shape.
The contact lenses must be thoroughly fitted and regular checkups and changing the lens may be required to maintain and attain good vision. To improve contact lens fit, sometimes intracorneal rings and Intacs, , are used.
To halt the progression of keratoconus, a new treatment option under investigation is corneal crosslinking
Due to contact lens intolerance, scarring or extreme thinning in severe cases, a transplant of the cornea may be required. This is a surgical method in which the keratoconus cornea is replaced with a healthy donor tissue.
