What is Cataract?

Cataracts – also called cataracts – are a clouding of the lens of the eye, which is located just behind the pupil. The eye lens consists mainly of water and proteins. The proteins are arranged in such a way that the eye lens remains clean and light can pass through it. As we age, some of these proteins can stick together and cloud a small part of the lens. This is a cataract, which over time can grow larger and cloud more of the lens making it harder to see clearly. Cataracts normally progress slowly, causing gradual vision loss. If left untreated, cataracts can result in blindness.

There are several types, but they all have the common feature of affecting the transparency of the eye lens. The more cloudy the lens, the more advanced the eye condition. Cataracts are the most common cause of vision loss in people aged 40 and over and are the leading cause of blindness worldwide.

Being told that vision is affected can turn the world upside down. When the first emotions subside, the knowledge that one is not alone may provide support. There are many people in the same situation, some who have just been diagnosed themselves and some who have been living with Cataracts for years.

If you experience poor vision as a result, there are devices available that can help with the tasks you have difficulty with. These aids can provide support with tasks that require vision and can help you continue to lead a full and independent life.

What can one expect from Cataract?

This eye condition can occur in one or both eyes. If symptoms occur, new glasses, magnification, appropriate lighting or other aids can be used for a considerable period of time. If the cataract spreads, one may consider cataract surgery, in which the eye lens is removed and replaced with an artificial lens. Cataract surgery is very effective in restoring vision. Discuss the situation and the options with the eye specialist to determine the best options.
