Omni Eye Centre Introduces New Technology

by | May 6, 2016

At Omni Eye Centre, we’re proud to be the first eye care clinic in Australia to incorporate the Topcon Triton, or OCT. An OCT is an instrument also known as an Optical Coherence Tomography instrument, which uses ultrasound by way of light waves. And in this case, the Triton has a laser light at a 1,050 nm wavelength to scan the inner layers of the eye, looking at the retina, the area behind the retina known as the choroid. And we’re able to pick things up, such as patients with macular degenerations and glaucoma far earlier than any other form of technology because of the high resolution. It’s almost at a molecular level form of resolution.

We can also look at blood flow. And there’s a type of procedure known as OCT angiography, which allows us to look at what’s happening at the back of the eye with better penetration, wide deep scans, and invisible scans. It’s a fantastic form of technology, a very exciting form of technology. Patients can come in, the scan is done almost in a blink of an eye – that’s how quick it takes – and quite often, we don’t actually need to dilate the eye. We can do it without putting drops in, so it’s non-invasive, and it’s a very accurate way of looking at what’s going on in the back of the eye.

Just for an example, we had a patient come in today, who has a family history of glaucoma, had been seen elsewhere, and we put him on the instrument and scanned the optic nerve in the eye. And the high resolution of the Triton picked up early changes in the nerve fiber layer. Well, unfortunately for the patient, but fortunately that we picked the condition up, he was diagnosed with glaucoma and treatment was commenced.

There’s also a tracking system known as SmartTrack, which is a very useful tool to compensate for the involuntary eye movements that are associated when taking scans. You know, people who experience an X-Ray or an MRI know that if they move during a scan or a procedure, then the results are not repeatable or reproduceable or valid. And this is a good thing about the Triton because it picks up these little tiny movements, and we’re able to track the eye in the X and Y and also in the Zed plane to ensure that the scanning instrument is accurate and repeatable and reproduceable.

So the OCT is now a standard of care when you come and get your eyes examined. Gone are the days where it was just an occasional test to do. These days we can look. We can photodocument the color photos that the Triton produces – amazing. There’s a low intensity light flash associated with these photos, so it’s a lot more comfortable for the patients. As I said before, it doesn’t take very long.

So if you do need to get your eyes examined, whether there’s a family history of glaucoma or macular degeneration or any other form of pathology, come and talk to us and we’ll be more than happy to discuss all the different options. We’re truly happy and excited to have this type of technology here at the practice.
