The cataract is the most common eye disorder. It affects one out of five people between the ages of 65 and 75, and every second person over the age of 75.

The formation of a cataract is part of the normal ageing process. As we grow older, chemical changes which take place in the eye lens can cause a decrease in the light transmission of the lens, or blurring.

A cataract is not a film or membrane on the surface of the eye lens but the modification of the internal structure of the lens. Because of this, it is harder for light to get into the eye and this light is scattered, vision is weakened, and the intensity of colours decreases, as does our perception of them. These symptoms develop gradually over months or years.

Modern science has found no drug therapy or diet that can slow down the development of cataracts or reverse the process.

Cataracts can only be cured surgically,, during which the greyed lens is removed and is replaced by an implantable artificial lens. The operation, with the implantation of an artificial lens, restores the necessary visual acuity and quality of vision. The technique is safe and effective.
