As we age, the lenses of our eyes can naturally become cloudy because of the degeneration of proteins of the lens and this can cause foggy or blurred vision known as Cataracts.

There is no need to live with these effects, though, as highly effective surgery is available which can correct this condition with ease.

This surgery is straightforward, painless and very quick. Although most often undertaken by patients in their 60s and 70s, this procedure is suitable for both younger and older patients.

Cataracts occur naturally as a consequence of ageing, but can also be caused by inflammation or injury to the eye, through medical conditions such as diabetes, steroid therapy and some people can be born with cataracts.

What Replacement Lenses Are Available for Cataracts?

When your natural lens is removed during cataract surgery (or refractive lens exchange) it will be replaced by an intraocular lens (IOL). These are medical devices, which are implanted inside the eye in place of the natural lens, and there are several types of IOL to choose from.

Your consultant will determine the best lens for your eye at your consultation.

How Might my Sight Affected by Cataracts?

Cataracts normally develop slowly and will not affect your vision very much at first. When the lens gets more cloudy the light passing through it is affected, meaning your sight will become affected too.

  • You may often check that your glasses need a clean, or notice that they look scratched when in fact they are in good condition.

  • Your prescription for glasses might change more frequently.

  • You may perceive colours as being faded or looking washed-out.
  • You may experience double vision.
  • You may start to have difficulty recognising people’s faces.

How Bad do my Cataracts Need to be Before I can have Surgery?

Your cataracts do not need to be ‘ripe’ before they can be removed.

The very low risk of complications in the surgical technique and the benefits of modern intraocular lenses mean that cataract surgery can be appropriate for you if your symptoms trouble you sufficiently.

How does Cataract Surgery help?

During cataract surgery your cloudy lens is replaced with a silicone or acrylic lens. Different types of replacement lenses are available, and if your condition allows, you may be able to choose between a regular monofocal lens – after which you will still need to use glasses – or a multifocal lens that’s designed to give you a degree of freedom from glasses for most everyday tasks. Not every patient is suitable for multifocal lens implants, so we can discuss your particular case at your consultation.
