Cataract operation

The natural clear lens in your eye helps you to see clearly by focusing the images. A cataract is clouding of the lens in the eye.  As a result of a cataract, your vision becomes blurry, like looking through a frosted glass.

Your surgeon will assess you to see whether you need cataract operation. However it is your decision to go ahead with the operation or not. This document will give information about the benefits and risks to help you to make a decision. If you have any questions that this document does not answer, you should ask your surgeon or his team .

Alternatives to operation

Glasses may improve your vision to some extent; if the cataract is advanced glasses will not help and surgery is the only option.  If you decide not to have the operation your vision will get worse gradually but not straight away.


You can have a light meal before your appointment. You will need someone to drive you home. If you work, please allow at least a week off work. You may require more time off if you work in a very dusty environment. Please read the following information as well as the content of the consent form.
