Cataracts occur as a part of the normal ageing process. Scientific studies show that virtually everyone past 65 years of age develop some form of cataracts in their eyes. This occurs because the crystalline, natural eye lens, turns opaque reducing vision.
Many years ago cataracts were a cause of blindness, and presently they greatly reduce the vision.
There is no known way to prevent the formation of cataracts developed with age, however, it has also been associated with the exposure to ultraviolet radiation, particularly from the sun.
Fortunately, modern surgical techniques, the implant of intra-ocular lenses with ambulatory surgery (of one day) and with local anesthesia, provide a safe, fast and effective solution.
More than 50 per cent of people over the age of 60 and some younger ones still suffer from cataracts. Cataracts are so common that it is said that everyone will suffer from them if they live long enough.
