What is a cataract?
A cataract is when the natural lens in your eye becomes cloudy, usually caused by ageing (see figure 1). A cataract causes blurred vision or changes the focus of your eye.
What are the benefits of surgery?
Your vision should improve.
Are there any alternatives to surgery?
New glasses may improve your vision to some extent, but if the cataract is too advanced, surgery is the only option to restore your vision.
