♪ [music] ♪ This animation explains what happens
during a cataract eye surgery. ♪ [music] ♪ Cataract surgery involves replacing the
cloudy lens inside your eye with an artificial one to improve vision.
Cataracts occur when the lens in your eye becomes cloudy, causing blurred vision. ♪ [music] ♪ Let’s take a closer look. The lens of the
eye is a clear, transparent disk that sits in its own
capsule behind your pupil. It focuses light that passes through to
the back of your eye, the retina, helping you to see clear, sharp images.
If you have a cataract, the lens inside your eye becomes cloudy. ♪ [music] ♪ For the operation, your surgeon will put
some drops in your eye to widen your pupil and relax your eye muscles.
You’ll also be given a local anaesthetic. Once the anaesthetic is working,
a small incision is made to the front of your eye, the cornea,
to remove the damaged lens. This is usually done by ultrasound to
break up your lens into small, removable fragments. A new,
artificial lens is then inserted. This is known as an “interocular lens,”
and is measured for your eye before surgery using a process called
“biometry.” There are different types of interocular lenses,
and your consultant will advise which is best for you. ♪ [music] ♪ Your surgeon will usually
leave your eye to heal naturally without stitches. Cataract surgery lasts
less than one hour, and you should be able to go home the same day.
Your eye may look red and bruised at first, but this will disappear after a
few days. Some people may experience blurred vision for some time after
surgery. This is because your eye needs to recover and adjust to the new lens.
Your consultant will tell you when you can have your eyes tested again. ♪ [music] ♪ For more information,
