Keratoconus: causes and treatment options

Keratoconus – Progressive thinning and distortion of the cornea Keratoconus is an eye disease of the cornea: the thin, clear tissue covering the surface of the front of the eye.

It is a progressive disorder that can either progress rapidly or take years to develop. It may affect only one eye but more commonly occurs in both.

Keratoconus Subsidy – Need Help?

If you suffer from keratoconus, there is financial help available. What is keratoconus? Keratoconus: progressive thinning and distortion of the cornea causing reduced vision. The cornea is the window of the eye. Light travels through the cornea past the lens to the retina and then the brain to form a visual image. A normal, healthy cornea holds its round shape. However, sometimes the cornea becomes structurally weakened and loses its shape. Instead of a dome, the cornea becomes cone shaped and the surface irregular. This prevents the light entering your eye from being focused correctly on the retina, so a

Myopia – what you can do

Myopia is the medical term for nearsightedness. Myopia is where the eyeball is too long or too powerful. The result is blurred vision; far away objects become blurry, but vision for close objects is clear within a certain range. 60 years ago, 10-20% of the Chinese population was short-sighted. Today, up to 90% of teenagers and young adults are. In Seoul, 96.5% of 19-year-old men are short-sighted. In USA and Europe, approx. half of young adults are myopic, double the prevalence of half a century ago. Worldwide, it is estimated that 2.5 billion people (roughly 1/3 of the world population)

What is Myopia?

Myopia, or shortsightedness is a refractive disorder. Myopia occurs when the eye physically grows too long. When a light wave enters the eye, it is bent by the cornea as it makes its way through to land on the retina – the light-sensitive tissue in the back of the eye. If the eye is too long, the lens of the eye focuses the image in front of the retina instead of on top of it. People with myopia have good near vision but poor distance vision. Causes of myopia Myopia is most often inherited. However, the recent dramatic increase in the prevalence
