What is cataract eye treatment?

A cataract is a clouding of the lens in your eye, which makes it more difficult for you to see. In a cataract operation, the cloudy lens is replaced with an artificial lens, giving you back the clear vision you once had.

No-stitch surgery

You won’t have to stay overnight in hospital for your cataract operation. You could be home within one hour of your operation, thanks to Eye Institute’s pioneering ‘no-stitch’ cataract surgery technique. And thanks to advanced surgical techniques you could be back to normal in just a few days.

Cataract procedure step by step

  1. Before your operation, you’ll be given eye drops to dilate your pupil. You’ll also have the option of a mild sedative.
  2. A painless local anaesthetic will be administered, and the skin surrounding your eyes will be cleaned, with sterile drapes placed around your head and face.
  3. Using the pioneering ‘no-stitch’ cataract surgery technique developed by surgeons at Eye Institute, the cataract is removed and the new lens is inserted through a very small, self-healing hole. This highly advanced technique means you’ll benefit from dramatically reduced recovery time.
  4. You'll be aware of your Doctors voice and that of the nursing staff throughout the cataract operation, but you will feel no pain, and only mild discomfort. An anaesthetist or nurse will be with you the whole time, to make sure you are completely comfortable and at ease.
  5. After the cataract operation you’ll be able to rest in comfort and enjoy a tea or coffee. Most patients are able to go home within just one hour of cataract surgery, and you should be able to carry on normal activities, such as driving, walking and sports, in a matter of days.

How the surgery is customised to your eyes

Just as there are different types of glasses, there are also different types of intraocular lens (IOL) that can be fitted during your cataract operation. It may even be possible to improve your eyesight to such an extent that you no longer have to rely on glasses at all.

Lenses used in a cataract operation can be:

  • Single focus intraocular lenses – to correct long or short sightedness
  • Dual focus intraocular lenses – to correct both long and short sightedness (in 80% of patients)
  • Toric intraocular lenses to correct astigmatism

The no-stitch technique explained

Using the pioneering ‘no-stitch’ cataract surgery technique, which was developed by surgeons here at Eye Institute, the cataract is removed and the new lens is inserted through a very small, self-healing hole. It’s an innovative method that makes surgery safer, and means you benefit from clearer vision sooner, with dramatically reduced recovery time.

Cataract FAQ’s

When should a person with cataracts have surgery?

Surgery is normally considered when loss of vision begins to interfere with your day-to-day activities or it is affecting your overall quality of life. 

Is the surgery permanent?

Yes. It’s not possible to get another cataract once it has been removed. However, approximately 10% of patients may become aware of a gradual blurring of vision some months to even years after the surgery as a result of the thickening of the lens capsule that supports your artificial lens. If this happens then clear vision is often simply restored by laser treatment, called a capsulotomy, which can be done very easily during a short visit to the clinic.

Will I need glasses after my surgery?

Most people will still need glasses for fine visual tasks although some patients can get by without them.

What if I have other eye problems?

There are diseases that can affect and limit your eye's visual improvement following cataract surgery. These can be diagnosed well before the operation and your specialist will discuss the impact of any such problems with you beforehand.

Does the procedure hurt?

No. An anaesthetic is applied before your surgery so that there is no pain, but some people experience slight discomfort after the surgery. 

How long does it take to recover? 

Recovery is very quick. You will want to take it easy for the first two or three days after surgery. 

What problems can happen after surgery?

Cataract surgery is very safe and has high success rates. However it is important to understand that complications can always occur during or after any surgery. Your surgeon can talk you through any possible problems.
