Advanced technology

The equipment behind every accurate diagnosis

Precise eye care starts with precise instruments. Our suite of advanced diagnostic technology supports everything we do, from swift, accurate refraction to the early detection of sight-threatening conditions and the fitting of our custom-designed scleral lenses.

Refraction

The eye test, without the guesswork

Our Nidek RT-3100 Intelligent Refraction Unit revolutionises the traditional eye examination. Say goodbye to the tedious "1 or 2" lens clicks: this automated system offers smooth, rapid lens selection for quicker, less fatiguing and highly accurate eye examinations. Seamlessly integrated with a digital chart, it provides diverse chart options, removing the need for memorisation and catering for all ages and literacy levels.

Comparing against your old spectacles is now possible too. Lens movement is smooth and almost instantaneous, so you can genuinely appreciate the change in your prescription, if there is any at all.

Fundus photography

Exploring the depths of eye health

Fundus photography enables non-invasive exploration of the posterior segment of the eye. Beyond assessing ocular health, it reveals insights into systemic diseases such as diabetes, multiple sclerosis and hypertension. Within the limited view through the pupil we observe the critical macula and the optic nerve, the conduit for visual information to the brain. It aids the early detection of conditions including diabetic retinopathy, glaucoma, retinitis pigmentosa and age-related macular degeneration.

Fundus photograph of another healthy retina — **Another healthy fundus**, photographed at the practice.

Fundus photograph showing diabetic retinopathy with yellow exudate deposits — **Diabetic retinopathy.** The yellow deposits are called exudates and are a hallmark sign.

Fundus photograph showing the pale optic nerve found in glaucoma — **Glaucoma.** Note the pale optic nerve. Glaucoma is the second leading cause of blindness.

Corneal topography

Mapping corneal precision

Our corneal topography system constructs a detailed 3D map of the cornea. It serves many roles, from assessing corneal shape to diagnosing conditions such as keratoconus. Notably, it plays a pivotal role in the design of custom contact lenses, offering a cost-effective and time-efficient approach by simulating multiple virtual fits before an actual lens is produced.

There are many cases where patients have been unable to improve their vision with spectacles, and the topographer has shown why, detecting surface abnormalities on the cornea from dry eye to ulcers. As a diagnostic tool it can also detect meibomian gland dysfunction, one of the main causes of dry eye.

Why this matters to you

Technology in the service of clinical judgement

Instruments do not fit lenses or diagnose disease; experienced clinicians do. What this equipment provides is the detail: earlier detection of sight-threatening conditions, and the precision behind every custom scleral lens and Ortho-K fit we design.

Earlier detectionSight-threatening conditions such as glaucoma and macular degeneration identified sooner.

Precision fittingVirtual lens fits simulated before production, saving time and cost on custom lenses.

Whole-body insightRetinal imaging can reveal signs of systemic disease, including diabetes and hypertension.

Slit-lamp biomicroscopy

Illuminating the front of the eye

The slit-lamp biomicroscope provides high-resolution, magnified views of the anterior structures of the eye. It is instrumental in diagnosing a spectrum of conditions, including dry eye, foreign body injuries, red eye presentations and lid anomalies. It is also an indispensable tool in assessing the fit of contact lenses, ensuring optimal comfort and vision.

Ocular coherence tomography

OCT: vision precision beyond compare

Our OCT system functions much like a medical CAT scan, delivering profiled and magnified images of the eye. In ophthalmology, OCT is indispensable for the early detection of sight-threatening diseases such as glaucoma and macular degeneration. It is also instrumental in refining the fit of our custom-designed scleral lenses, providing an intricate, close-up view of the interaction between lens and eye.
