Cataracts are a normal part of aging. About half of Australians aged between 50 to 80 have cataract formation of some degree. Factors like sun exposure, genetics and medication can influence the condition and cause early onset. It is not uncommon for me to see patients in their mid to late 40’s with cataracts causing visual symptoms.
Most people with cataracts have a cataract in both eyes. However, one eye may be worse than the other. Some people with a cataract, don’t even know it. Their cataract may be in the early stages, or the changes in their vision may not bother them. Some people who have cataracts cannot see well enough to do the things they need or want to do.
Most people have plenty of time to decide about cataract surgery. Many people are motivated to have it earlier so they can reduce their dependence on glasses or contact lenses. I cannot make the decision to undergo surgery for you, but having a consultation with me will help you make an informed decision to undergo surgery or not.
Consider the statements below & whether they apply to you:
I perform cataract surgery 100% with drop local anaesthetic applied to the eye. Unlike other centres in Western Australia, I do not use any needles to inject in the patient’s eye. I can also perform the surgery under general anaesthesia in certain circumstances on request if you are nervous. My aim is to keep the patient as calm and comfortable as possible for this life changing operation. A cataract operation takes around 10 to 12 minutes per eye to complete. I can also use the Catalys laser machine to make precise incisions and a perfectly round opening in the natural lens for superior visual outcomes.
Each eye is operated separately on different days but I can always accommodate my patients who wants both eyes to be operated at a time. Bilateral same day cataract surgery is a very safe and well established option.
Cataract surgery is done at a day surgery as an outpatient procedure. You will have surgery and return home the same day to recover.
Visual recovery usually takes 2-3 days where patients can drive or fly again.
Patients undergoing cataract surgery has exactly the same access to premium lenses as patients undergoing a
Refractive Lens Replacement.
Not everyone is the same and not every patient has the same visual requirements. There are various different lens types available on the market to suit every individual.
I will perform an extensive and comprehensive analysis of your eyes, lifestyle and occupational needs to determine the best lens suited to you as an individual.
I will tailored your lens type to your specific needs and goals.
As a rule of thumb, the more spectacle free a patient wants to become, the more nighttime glare and quality of vision issues a patient will have. This is because as the range of a lens increases, the more extra optical properties a lens has. This can compromise your quality and night time vision.
Spiral optics intraocular lenses are the latest technology intraocular lenses (IOL’s) available to patients, using revolutionary spiral optic technology to precisely manage the light entering your eye.
I was the first surgeon in Western Australia to implant this specific technology lens and was one of 10 surgeons worldwide to be requested by the company producing these lenses to conduct outcome research. I am also the surgeon in Australia who have implanted the most spiral optics lenses to date as I regard these lenses as the closest we have available to the “perfect” lens.
These IOL’s are designed to provide you with high quality distance, intermediate and near vision without glasses.

What you can expect to see with a Spiral Optics IOL following surgery
As the word “mono” (one) implies, monofocal lenses has only one focal point. These lenses can either be focussed for distance vision or near vision in both eyes.
Monofocal lenses as a rule do not cause nighttime glare and halo complications and the contrast sensitivity or quality of vision is not compromised
Example of a clear monofocal lens. These lenses have no extra properties and can either be focussed for distance or near vision- not both
Monofocal PLUS lenses are highly versatile intraocular lenses that induce natural optical properties known as l spherical aberrations to enhance the depth of focus. In other words a single focal point with a little bit of extra range of vision around it.
As these lenses has a range of vision they can be implanted with different focal points in each eye giving patients “Pseudophakic Blended Vision”- very similar to
Presbyond.
Monofocal PLUS lenses do not cause glare symptoms at night and contrast or quality of vision is not affected
Example of a monofocal PLUS lens. These lenses have internal properties which induced natural optical phenomena known as spherical aberrations which enhances the patient’s depth of field
Extended Depth of Focus or EDOF lenses are the most modern type of lenses that can achieve spectacle independence.
EDOF lenses elongates a single focal point and gives an extra range of vision of 1.5-1.9 optical units or more.
These are extremely versatile lenses that can be implanted at various focal points to achieve spectacle independence.
EDOF lenses can also be used for Pseudophakic Blended Vision with an enhanced range with what is possible with Monofocal PLUS lenses.
EDOF lenses do cause night time glare though it is minimal and studies shows that most patients become accustomed to it over time.
Contrast sensitivity or quality of vision is minimally affected by EDOF lenses.

Multifocal lenses give patients distance, intermediate and excellent reading vision without the need for reading glasses.
Multifocal lenses have rings (known as diffractive rings) in the lenses which splits light into 3 focal points, one for distance, one for intermediate and one for near vision. These lenses are general known as Trifocal lenses as they have 3 distinct focal points
With multifocal lenses patients are able to read small text comfortably without the need for reading glasses.
Because multifocal lenses have rings in them, they can cause glare and halo symptoms at night time.
Multifocal lenses are aimed at distance in both eyes.
Due to the rings and light splitting technology, both eyes can see distance, intermediate and near.
The advantage of multifocal lenses is that both eyes do not need to be focussed at different points.

In many instances patients opt to undergo early cataract surgery. In modern cataract surgery you do not have to wait for a cataract to “ripen”.
Whether you are ready to take the plunge into a world of crystal clear vision, or just have a few questions for me, feel free to drop me a line.

I'm proud to have earned glowing reviews from patients who I've helped own their vision allowing them to enjoy a life free from the constraints of glasses and contact lenses. I'm humbled by the the overwhelming positive online reviews on Google.
