Cataracts
Long term exposure to ultraviolet light from the sun can cause the lenses in our eyes to become cloudy or opaque, which affects the vision. This is known as cataracts and is a change in the lens material rather than a growth.
What causes cataracts?
Although this is generally the result of ageing but it can also result from exposure to radiation or toxic substances or even trauma to the eye. In rare cases cataracts can be present at birth. Wearing dark sunglasses and a hat outside may help prevent this condition.
Cataracts are very common in people over the age of 65 and a family history of cataracts can increase the likelihood of developing the condition. Over time cataracts will generally get worse, with increased cloudiness of the lens causing the patient’s sight to become worse and affect their quality of life.
What is the treatment for cataracts?
Surgery to replace the clouded lenses with synthetic ones is quite common and usually straightforward. The optometrist will refer the patient to an eye specialist for examination and surgery if they detect cataracts. Cataract surgery is now a relatively minor and straight forward procedure, usually performed as an out-patient. Most patients will have an intraocular lens inserted at the time of surgery to replace their own cloudy lens.
