First Swept Source OCT install in Optometry

One of the UK’s most prolific and well-respected optometric and ophthalmic equipment researchers, Professor James Wolffsohn, Deputy Executive Dean at Birmingham’s Aston University, will unveil the world’s first and only swept source 3D OCT on the Saturday of Optrafair, on the Topcon stand, at 1pm.

Launching at the NEC-held event, the DRI OCT Triton is the only OCT that sees through blood and cataracts and the world’s fastest[1]scanning speed of 100,000 A-Scans/second. In addition to anterior segment scanning, the DRI OCT Triton can visualize deeper pathology, rapidly penetrating ocular tissues such as the choroid and even the sclera and provides double the data of a conventional OCT.

There are only currently three Triton units in use in the UK. All three of these pre-launch users have hailed the system as revolutionary.

Nicholas Rumney from BBR Optometry, Hereford, is the UK’s first optometrist to use the Triton. He says: “The Triton is as much of a jump forwards from a regular OCT as the launch of the OCT itself was. This is in a different stratosphere in terms of our ability to see structures that are totally invisible otherwise. The Triton makes our diagnostic skills much more accurate and eliminates once and for all any doubt over structures within the eye.

“As for what it will do for your relationship with your local hospital, optometrists in general have to work harder to attain a level of diagnostic credibility in the eyes of ophthalmology. Nothing assists this more than your ability to analyse the 3D structures of the eye in vivo.”

Professor Paulo Stanga, Consultant Ophthalmologist & Vitreoretinal Surgeon at the Manchester Royal Eye Hospital and Professor of Ophthalmology and Retinal Regeneration at The University of Manchester, is the first UK-based ophthalmologist to use Triton. He says:“Swept source adds a new dimension to OCT.  The Topcon DRI swept source OCT is easy to use, provides unique clinical information, and has improved my practice.  For the first time we can in-vivo visualize not only the vitreo-retinal interface but also the cortical vitreous which is important at the time when more and more therapies are delivered via intra-vitreal injections.   Deeper imaging brings choroidal assessment into the picture and shows the role and value of measuring choroidal thickness, helping guide my clinical decisions.  Seeing more helps guide my therapy and allows me to treat more effectively.  I find Swept Source OCT an essential tool to look for biomarkers of disease regression or progression.”

Another early adopter is 26-year-old Puja Patel and her business partner, Baiju Shah, from One Vision Professional Eyecare, Old Amersham, Bucks, a practice opening its doors on 21 April. “At my practice, I will be giving my patients the best possible clinical service,” says Puja. “As an optometrist I want to be able to detect, refer appropriately and monitor my patients to the best standard of care I can provide. The new swept source OCT will aid me in providing an enhanced level of care to my patients. It is a key investment for my practice.

"The swept source OCT has an invisible light source which is much quicker than the older models. This eliminates re-runs and patients don’t have to stay still for so long. This new model provides a much sharper image, showing a clear, smooth transition between the different layers of the eye. I am looking forward to using this new innovative piece of equipment on my patients when we open our doors to the public later this month.”
