More about what is Keratoconus?

We see through the cornea, which is the clear front window of the eye. A normal cornea has a dome shape, like a ball. In Keratoconus, however, the structure of the cornea is just not strong enough to hold this round shape. The cornea bulges outward and downward like a cone.  

The changes can result in blurred or distorted vision, glare and halos at night and the streaking of lights. 

Between age 12 and 35 it can arrest or progress at any time. It is impossible to predict how fast it will progress or if it will progress at all. After that progression slows and often stops. 

With severe keratoconus, the stretching of collagen fibres can lead to tears at the back of the cornea. It can swell and take months for the swelling to go away. This often causes a large corneal scar that impairs vision. 

Keratoconus should be diagnosed, followed up and treated to prevent complications. If you struggle to see with your glasses and your vision continually deteriorates ask you eyecare professional to screen for Keratoconus. 

I will discuss treatment options in the next few posts.
