Cataract surgery important information

The lens of each eye must be clear in order for your eyes to work properly. A clear lens allows light to reach the retina at the back of the eye. The retina is part of the eye at the back which enables you to see things. With a cataract, less light reaches the retina, so your vision is typically blurred, with contrast sensitivity also being affected. Less contrast sensitivity reduces your ability to see objects as clearly in dim light. Also colour vision can be reduced, making normally bright colours appear duller.

A cataract can be present for a while before you notice you have one. Regular eye tests identifies cataracts at an early stage, so it is important to keep up to date with eye examinations. Ideally, you should have your sight checked by an optician every two years, although people over 60 years old may be required to have eye tests every year.

If you have a cataract, it will continue to develop. The only way to restore your vision is by having the cataract removed by surgery. Cataract surgery is one of the most common and quickest surgeries performed, and many people are able to return to their usual daily routine after 24 hours.
