Eye Care – Technology

We use a range of sophisticated equipment and diagnostic tests to properly assess and treat your vision needs. These include the Keeler digital slit-lamp, visual fields, a tonometer and digital retinal photography. Here’s how they work.

Keeler digital slit-lamp

We use a Keeler digital slit-lamp, or biomicroscope, in every standard eye test. This allows us to get a three-dimensional view of the anatomical parts of your eyes, and observe the microstructure and physiology from the front of your eye (cornea, lids, conjunctiva), all the way to the back of your eye (retina, optic nerve).  High powered optical quality lenses and a beam of light help magnify these structures, which assists us in identifying disorders, infections or any other potential eye issues during your eye exam. Examination with the digital slit-lamp is particularly important if you suffer from dry eye disease, as it helps us assess the function of your Meibomian glands and the health of your eyelid margins which can impact the hydration state of your eye.  

Visual fields

To assist us in detecting blind spots – also known as scotomas – we use visual field tests. Scotomas may indicate signs of eye disease such as glaucoma, or even more serious conditions such as a brain tumour.   Visual field tests are a vital way of uncovering valuable clues about the presence and possible severity of diseases in the eye, optic nerve and visual function of the brain.


Glaucoma is one of the leading causes of blindness in adults over 60. To ensure it’s both detected and treated early, we use a tonometer to measure the pressure inside your eye (intraocular pressure or IOP). Air pressure is applied to your eye in the form of a brief puff of air on your cornea (don’t worry, it doesn’t hurt) and provides an accurate eye pressure reading. This allows us to identify changes in your eye pressure long before you’re physically aware of them, ensuring any signs of glaucoma are treated immediately.

Digital retinal photography

Digital retinal photography allows us to take a high-resolution photograph of your retina, optic nerve and blood vessels. Close screening of these helps us establish a baseline from which we can monitor your vision over time, and screen for early signs of diseases like glaucoma, macular degeneration and retinal changes associated with diabetes.

Small changes can make a big difference to your visual and overall health over time, and you may not realise they’re occurring, which is why we recommend a full eye exam, complete with digital retinal photography on a regular basis. What’s ‘regular’ for you depends on your eye health, and will be determined by your optometrist on your next eye test.
