Keratoconus changes the shape and structure of the cornea (the outer window of the eye), which can make it thinner and weaker.
Symptoms of keratoconus include blurred and distorted vision although in the early stages of the condition, vision is often unaffected.
There's no firm evidence to confirm the causes of keratoconus, some believe that it could be genetic as there have instances of keratoconus affecting more than one member of a family. It has also been suggested that those who suffer from multiple allergies are also thought to be at risk.
Corneal crosslinking can help many patients who are suffering from keratocounus, or form conditions associated with it. The procedure can help show the progression of karatoconus and potentially avoid the need for more invasive treatments like corneal grafts.
Typically, corneal crosslinking involves using a combination of Riboflavin (Vitamin B) drops and ultraviolet light to strengthen and stabilise the collagen fibres in the cornea. The procedure has shown excellent results after just one treatment.
Once the cornea is stable, it is possible to consider further procedures such as Laser Vision Correction or Refractive Lens Exchange which can reduce the dependency on, and can even overcome the need for glasses and contact lenses.
