What is a Cataract?

It is where the internal lens of the eye becomes cloudy so it is more difficult to see. 

What is the Lens?

The crystalline lens is inside the eye directly behind the coloured part, which is called the iris.

Little muscles are attached to the lens. These can move and alter the shape of the lens to help you focus on what you want to see.

What causes Cataracts?

The most common cause is ageing, but occasionally they happen because of injury or sudden trauma. Some medications are also known to increase the rate at which a catarct may form.

What are symptoms:

  • slight blurring of vision
  • spectacles always seem to need cleaning
  • seeing slightly double
  • change of colour vision, becoming more yellow
  • difficulty with glare and bright lights.

What can be done?

In the early stages of cataract development you may need to change your spectacles more frequently to help you see clearly.

Will I need an operation?

When your vision affects your everyday life – such as driving, watching TV, or reading – then your optometrist will refer you to an eye hospital. It’s the most commonly performed surgery in the UK today and takes anywhere from 10 – 25 minutes to comlete the procedure.

What does the operation involve?

It is often carried out under local anaesthetic, and usually as a day-case procedure (no overnight stay). The cloudy lens inside your eye is removed and replaced with a new synthetic clear lens. You get to go home after a short stay for some routine checks and use eye drops for 4 – 6 weeks until you have a post op appointment to confirm everything has settled.
