How does cataract surgery work?
Assessment & discussion
If your doctor or optometrist suspects you have a cataract they will refer you to an eye surgeon for a full assessment. After the initial consultation at Vision Eye Institute, an extensive range of tests will be performed using the latest diagnostic equipment. These tests will include:
- A full vision assessment
- Measurement of the pressure in your eye (IOP)
- Assessment of your retina
- Measurement of your eye length to help determine the correct replacement lens for you
Your surgeon will then discuss the proposed surgery and answer all of your questions regarding the benefits and risks of surgery so you can make an informed decision.

How is cataract surgery performed?
New and continually evolving surgical techniques and anaesthesia options, as well as the leading technology provided at Vision Eye Institute, have made cataract surgery a remarkably safe and effective procedure. It all can now be done as day-surgery, without needing a hospital stay. After surgery patients can resume normal activities, such as driving, walking, and sports, very quickly, usually within a few days.
Cataract surgery is the procedure of removing the cloudy lens of the eye, and replacing it with an artificial clear lens called an intraocular lens (IOL). Today, revolutionary microsurgery means that cataract surgery is performed through a tiny incision in the eye no more than 3 mm long. It is remarkably successful, and recovery time has been dramatically shortened compared to only a few years ago.
At the initial consultation, numerous tests are done in order to determine the suitability of the eyes for surgery, and to determine the optical prescription that will be required for the lens implant. Additionally, the patient and their family can be taken to view the day-surgery facility in order familiarise them with the procedures and the environment.

Can cataracts come back?
In the months or years after cataract surgery a small percentage of people will develop a condition known as 'secondary cataract', which can reduce the vision. However, this is not a true cataract, but actually a thickening of the back of the lens capsule. Fortunately, this secondary cataract (more correctly called posterior capsular thickening) can be easily treated. A quick and painless laser treatment (YAG laser capsulotomy) makes a small opening in the back of the lens capsule, which restores vision within hours. When people remark that they know of someone who "had a cataract removed by laser", they are probably referring to this process.
