Cataract

Cataract is the leading cause of blindness worldwide, and one of the most common forms of treatable vision impairment in Australia. Cataract surgery is a wonder of modern medicine, and is one of the most commonly performed surgical procedures.

What is a cataract?

The crystalline lens forms part of the focusing system of the eye, and is situated around 3mm behind the cornea (the clear part of the eye in contact with the outside environment). A cataract develops when the crystalline, lens which is normally clear, becomes cloudy. This impacts the quality of the vision and, in severe cases, can lead to blindness.

Why do we get cataracts?

Cataracts usually develop with age, as the normal proteins present in the lens begin to break down and cause it to become cloudy. Other factors that may affect the development of cataracts include; genetics (family history), concurrent illness, use of certain medications, trauma to the eye and UV exposure.

What can be done about cataracts?

In the early stages of cataract, there may only be mild effects on the vision. At this stage, no treatment is necessary other than perhaps changing your glasses prescription a little more frequently.

As the cataract develops, the vision will continue to decrease and start impacting upon your ability to carry out common daily tasks such as reading or driving. At this time, it may be necessary to consider cataract surgery.

What is involved in cataract surgery?

Cataract surgery is done as a day procedure, usually under local anaesthetic. An anaesthetist will inject an anaesthetic medication into the eye socket which will render the eye numb, unable to move and mostly unable to see. Most patients are unable to even tell if their eye is open or closed.

Your ophthalmologist will then perform an operation lasting around 30 minutes to painlessly remove the cloudy lens from inside the eye, and replace it with a clear synthetic lens implant.

Recovery time from cataract surgery is usually very minimal and you should notice improved vision within a few days of the surgery.

Are there any risks associated with cataract surgery?

All surgical procedures carry some risks, and it is important to know about these prior to making a decision at to whether to proceed with surgery. Your surgeon will discuss these with you during the initial consultation process, and provide you with more detailed written information so you can make a fully informed decision about your treatment.
