Cataracts

Cataracts are generally a natural part of the ageing process and are typically associated with the elderly. They can, however, affect younger people too. Those most at risk of developing cataracts are people who have diabetes, have a high level of UV exposure, smokers and those who use steroid medications. A family history of cataracts, excess stress and trauma can also be risk factors.

A cataract is a clouding and yellowing of the normally clear lens inside the eye. They can occur in one eye or both eyes and are the most common cause of adult blindness worldwide. Cataracts develop slowly over a period of years and may not initially show any symptoms. Early signs may include the need for better lighting, greater magnification and a stronger prescription. As the condition develops, symptoms can include distorted or blurred vision, shadowing, halos around lights and the eyes may become more sensitive to light and glare. Activities like reading and driving at night may become more difficult.

Cataracts don’t heal or get better with time and will eventually need to be treated. Treatment in the early stages may include a strong visual aid prescription but as the symptoms worsen surgery may be required. Surgical treatment involves having the cloudy lens removed and replaced with a clear, artificial lens. This surgery is very common and is usually done under a local anaesthetic. It is safe and painless and can successfully restore the eyesight to normal.

If you experience any of the abovementioned symptoms or see a noticeable change in your vision, you should book an eye test. Early detection of cataracts can prevent potential blindness.
