ABOUT THE CONDITIONS
THAT CONTRIBUTE IN VISION PROBLEMS
What is a Cataract?
This is a condition that involves the ageing and clouding of the lens within the eye. This ageing process will have an impact on how much light enters and reaches the back of the eye, ultimately leading to impaired visual performance. It can also be caused by diseases or injuries, while it may rarely be present at birth (congenital cataracts).
Cataracts can’t be treated with lasers or medication. Surgery is still the only treatment option. During surgery the cloudy lens is removed and replaced with an artificial one.
The natural lens of the eye is located behind the iris (the colored part of the eye), in a transparent bag which is called capsule.
The main symptoms of cataract are:
- decreased (blurred) vision (distant or near)
- fading colour perception
- blurred or significantly reduced contrast sensitivity
- poor night vision
- frequent changes in eyeglass prescription (increasing nearsightedness and decreasing farsightedness)
- sensitivity to light (photophobia)
- glare, reflections or rings may appear around bright lights (halos)
At an early stage, cataract can be treated with the prescription of glasses. However, this is a temporary solution. The total removal (treatment) of cataract is clearly performed through cataract surgery.
The most popular method of treating cataract is the technique of phacoemulsification with ultrasounds. It is a procedure of high surgery safety, thanks to the most advanced process being used.
