What is a cataract?
A cataract is a progressive clouding of the transparent lens located inside the eye. This phenomenon decreases the amount and quality of light that passes through the eye and which is necessary for vision. Vision becomes blurred, the perception of colours becomes dull and sensitivity to light increases.
Cataracts are one of the leading causes of visual impairment in the world and are considered a real public health issue. They generally occur in people over 60 years of age but can also affect young children (congenital cataract).
In the initial development of a cataract, the patients do not realize that they are suffering from the condition, because the effects on vision are minimal or absent. As the lens becomes more clouded, the symptoms worsen, causing significant deterioration of vision that can lead to blindness.
How to treat cataract?
The only effective treatment for cataracts is surgery. Cataract surgery is the most common surgery performed across all surgical specialties. Cataracts are a very common cause of declining vision. Significant progress has been made in the treatment of this condition in recent years and most people who suffer from this disorder can now expect to fully, or at least to a large extent, recover their eyesight.
During surgery on the eye, the surgeon removes the cloudy lens and replaces it with a transparent intraocular lens that has an excellent optical precision.
There are three natural lens replacement options: a monofocal, bifocal or trifocal intraocular lens. However, only the trifocal technology will allow you to live spectacle free.
