When should it be done? of Cataract surgery

The only way to remove cataracts is by having an operation. Not all cataracts are removed – it depends how seriously they affect vision. When a cataract stops you reading or driving, for example, surgery may be recommended.

The decision to remove a cataract depends on your lifestyle, age, and job. Some people’s job or hobbies may be less affected by declining eyesight than others.

In some cases, your doctor may recommend you have a cataract operation straight away to stop other eye complications developing. This may mean the cataract is removed even before it’s started to affect your sight, because there is another problem that needs treating and the cataract is in the way. Examples of other eye problems are diabetic retinopathy and macular degeneration, which are conditions that affect the blood vessels in the eye.

In the past, cataracts were often left until they completely clouded vision before being removed. Medical advances mean that surgeons no longer suggest waiting to remove a cataract, because this can make the procedure harder to perform.

While you are waiting for cataract surgery, there are some things you can do to relieve the symptoms. Eyedrops that widen your pupils may help you see better if the cataract is small and near the back of the lens. Wearing sunglasses protects your eyes from sunlight, and wearing a peaked cap can help to stop light from shining directly into your eyes. Keeping rooms well lit when indoors will help you to see more easily.
