How is cataract surgery performed?

Cataract surgery is usually performed as day surgery under local anaesthetic. Frequently your anaesthetist will also give you a strong sedative to allow you to relax. If necessary, a general anaesthetic can be given, however this is not usually preferred. It is uncommon to feel any discomfort during cataract surgery.

Cataract surgery usually only takes about 10 minutes. The cataract is removed using very small instruments and a microscope. After the cataract is removed, an intraocular lens is inserted to allow light to focus after the surgery. Almost always, no stitches are used.

After the surgery, you will stay at the hospital for up to an hour and then be allowed to leave. You will have a shield over your eye and will be given instructions on what to do when you get home. Usually you will start eye drops that night.

How do you determine the strength of the intraocular lens?

Before having cataract surgery we will take measurements of the eye. These are used to predict the strength of the lens required for your eye. This process is called biometry and more information about this can be found here.

Do you use lasers to remove a cataract?

Most surgery is performed with a highly specialised ultrasound machine. This gives excellent results the vast majority of the time.

There is a new technique using a femtosecond laser (called laser-assisted cataract surgery), which can offer potential benefits for some patients. For more information regarding laser-assisted cataract surgery, click here.

What are the risks of cataract surgery?

Cataract surgery is considered safe, low risk surgery. However, as with all operations, there are some risks.

Common risks:

worsening of dry eye symptoms (this usually settles down with time after the surgery)
worsening of floaters
refractive changes
watery eye
glare, haloes or unwanted reflections
droopy or puffy eyelids.

Uncommon or rare problems:

retinal detachment (less than 0.1%)
severe infection (less than 0.05%)
corneal decompensation (less than 0.1%)
posterior capsule rupture (with or without vitreous loss - less than 0.5%).

Cataract surgery is generally considered a safe procedure. The list above shows the potential risks and is included for completeness but permanent loss of vision from cataract surgery is very rare. Please contact the clinic if you would like more information.

Where is the surgery performed?

Our surgeons operate at a number of different hospitals to cater for both private and public patients. All of our surgeons offer NO-GAP surgery for HBF and DVA gold card holders. Currently we also provide surgery for public patients at Joondalup Health Campus.
