Why would I need cataract surgery? 

People who require cataract surgery have diminished vision due to a cloudy lens. It is most often age-related. 

What symptoms does cataract surgery address? 

Most people who have cataract surgery have restored vision afterwards and are able to resume normal day-to-day activities, including driving.

When should you speak to a specialist about cataract surgery?

If you are experiencing cloudy vision that has been caused by cataracts, it could be time to discuss the possibility of having cataract surgery with a specialist.

How is cataract surgery performed?

Cataract surgery takes approximately 30 to 45 minutes and is usually done under local anaesthetic.

The surgeon will make a small incision to your eye and remove the cloudy lens. It will then be replaced with a clear, artificial one.

What is the recovery for cataract surgery?

It is normal after cataract surgery to experience some discomfort (including blurred vision and watery eyes), but these side effects should go away after a few days.

You may be given eye drops and it is very important that you administer them as instructed by your surgeon.

You and your surgeon will discuss specific details of your recovery prior to the operation.

Are there any risks/complications associated with cataract surgery?

As with any medical procedure, it is possible for risks or complications to arise. It is best that you speak with your specialist or surgeon about how best to avoid any adverse reactions.

The chance of complications after cataract surgery is very low, but they can occur. Some of the most common risks and complications that have been associated with the procedure are:

• Severe eye infection
• A tear in the bag which holds the lens in place
• Clouding of the bag
• A detached retina
• Inflammation in your other eye
• Corneal abrasion
• Bleeding in the eye
• Fluid in the small spaces on your retina
• Cystoid macular oedema (swelling of the retina)
• Permanent vision loss

How can I prepare for cataract surgery?

Prior to cataract surgery you will meet with the surgeon who will discuss what you can expect and they will also take measurements of your eyes and eyesight.

You may also be asked general questions about your health and medical history.

It’s very important to ask any questions that you might have about cataract surgery with your surgeon prior to the operation.

Are there alternatives for cataract surgery?

Glasses can help with your vision initially, but as cataracts progress, the only option to restore your vision is to have surgery.
