If you have a cataract getting in the way of your daily activities and affecting your ability to drive or read, you may need cataract surgery.
Typical early signs of cataracts are:
- blurred vision or dazzle from lights (such as oncoming car headlights)
- increasing short sightedness (myopia)
- colours becoming duller
In the past, people with cataracts were encouraged to wait until they could hardly see. These days, surgery to remove a cataract can be done at any stage of development, once it is affecting your ability to function.
Your GP may recommend cataract surgery if you are at risk of developing another eye condition, such as:
Alternatives to surgery
The first signs of a cataract may be helped with:
- new glasses
- brighter lighting
- anti-glare sunglasses
- magnifying lenses
However, these will not stop the cataract growing and blurring your vision. There is no medication that can clear a cloudy lens.
Not having surgery
If your cataract is not interfering with your daily life, you may decide not to have the operation straight away. It is safe to leave a minor cataract. It does not become more difficult to remove a cataract should you decide to wait before having surgery.
However, without surgery, your lens will gradually become so cloudy you will not be able to see detail at all, although some light will always be distinguishable.
