Keratoconus is a genetic disease that progresses in the first 2 or 3 decades of life. It distorts and stretches the cornea, causing increasing short-sightedness and severe astigmatism. Eventually it may distort the cornea to such a degree that it reduces vision to a point where glasses and contact lenses are no longer useful. Though in some some people it continues throughout life, it usually slows and stops with age.
What can we do about it?
Corneal collagen cross-linking. The corneal tissue becomes more rigid and progression of the disease is stopped.The cornea is soaked in riboflavin (vitamin B2) using drops and exposed to ultraviolet light for half an hour. Move following to above The corneal tissue becomes more rigid and progression of the disease is stopped.
This is a treatment developed since approximately 2007 and has shown significantly better outcome than previously possible for eyes with disease that continues to progress. It is likely to prevent the long-term need for routine corneal transplant in affected patients. This was a common requirement in more extreme cases in the past.
