Cataract

Cataracts is a condition where the lens of your eye becomes cloudy. Your vision becomes hazy, darker, and less colourful. You may also experience vision loss. Cataracts are usually caused by aging, and may become more common around the age of 50. Cataracts can also be caused by trauma to your eye or diabetes.

Aging and exposure to sunlight can cause cataracts. Changes in your eyes are often a normal part of aging. But the changes do not always lead to cataracts. Cataracts can also happen after an eye injury, as a result of eye disease, after you use certain medicines, or as a result of health problems such as diabetes. Sometimes children are born with cataracts.

How are they treated?

Surgery can remove cataracts. For most adults, surgery is only needed when vision loss caused by a cataract affects their quality of life. There are a number of things you can do that may help you manage your vision problems. Many people get along very well with the help of eyeglasses, contacts, or other vision aids. Keep your eyeglasses or contact lens prescription up to date. Also make sure you have plenty of lighting in your home. You may be able to avoid or delay surgery.

Whether you need cataract surgery depends on how much of a problem the cataract causes for daily activities like driving and reading. Surgery is almost always by your choice (elective) and can be scheduled when it is convenient. For people who decide to have surgery, the surgery usually works very well.

Some people have to have surgery. Children are sometimes born with cataracts that need to be removed. Other people may get cataracts after an eye injury or as a result of eye disease or other health problems. Cataracts from these causes may also need to be removed.
