Canon: Xephilio OCT-A1
The Canon Xephilio OCT-A1 System, comprising OCT, RX Capture software, computer and LCD monitor, has a scanning speed of 70,000 scans per second with an optical depth resolution of three microns. The OCT averages up to 200 scans and offers specific scan modes for vitreous and choroid imaging with a scan width of 13mm. It can automatically detect and distinguish 10 layers of the retina and features 10 fixed, programmable exam pre-sets, comparing the results of five examinations in a time sequence. Fundus images taken on an optional retinal camera can be integrated into the OCT examination. Integrated scanning laser ophthalmic real-time retinal tracking technology automatically retains the scan position and protocol for each patient, eliminating the need for manual adjustment.
Optopol: Revo
Optopol’s latest software release boasts a posterior and anterior ‘full range’ feature for wider and deeper scans. Available across the Revo OCT range, the posterior B scan capability is increased from a 12mm to 15mm line scan, while the anterior B scan and anterior chamber radial full range examination provides cataract, cornea and glaucoma analysis with measurement and recording facility. A new artificial intelligence DeNoise algorithm filters out noise and enhances the visibility of morphological structures and provides greater retinal layer detail. Add-on IOL Formulas software includes Hoffer Q, Holladay I, Haigis, Theoretical T and Regression II formulas and WTW and P features. New and improved features of the re-designed Revo FC OCT include real-time eye tracking, auto flash, anterior photographs, photo intensity levels plus improved OCT optics and fundus optical systems.

Topcon: DRI Triton OCT
The Maestro2 provides colour fundus photography and automated non-invasive OCT angiography in one compact instrument. With a single touch, the Maestro2 automatically performs alignment, focus, optimisation and capture and displays an instant report. Even less-experienced operators can capture a 12x9mm widefield OCT scan in seconds, encompassing the macula and optic disc. Analysis tools, including the ‘hood report’, support visual field decisions and OCT-A (angiography), allowing for careful monitoring. This year, Topcon has also added PixelSmart technology to its Triton Swept Source OCT, which ‘reduces speckle noise and improves contrast, further enhancing 3D scan quality’. The DRI Triton combines swept-source OCT technology with multimodal fundus imaging. It has a scanning speed of 100,000 A-scans per second, producing clear B-scans, while an invisible 1,050 wavelength visualises the deepest layers of the eye in a single image.

Heidelberg Engineering: Anterion and Spectralis
The Anterion swept-source OCT offers topography, tomography and anterior segment metrics and axial length in one upgradeable, modular device. The Spectralis combines confocal scanning laser ophthalmoscopy (cSLO), spectral domain OCT and patented eye-tracking technology for the posterior segment. The upgradeable, modular imaging platform enables clinicians to add the latest technology, while protecting their patient data. Images can be taken in any lighting condition with no pupil dilation, even through cataracts and contact lenses. The Spectralis averages 100 B-scans, even in a volume scan, providing high resolution images of 10 retinal layers. TruTrack Active Eye Tracking technology mitigates for eye movements by freezing the retina to capture a precise image and accurately repositions the OCT scan at follow-up appointments so that changes as small as one to two microns can be identified.
Optos: Monaco and Silverstone
Monaco and Silverstone combine ultra-widefield (UWF) retinal imaging and integrated OCT to diagnose, document and treat ocular pathology. Monaco combines optomap UWF imaging with cross-sectional 40 degree OCT views of retinal structures to produce colour, autofluorescence and central pole OCT scans in just 90 seconds. OCT scans are registered to corresponding optomap images facilitating detailed examinations and scan comparisons between visits. The Silverstone UWF imaging device with optomap guided swept source OCT produces a 200 degree single-capture ultra-clear retinal image in less than half a second and, with just a touch, it can capture line and volume scans anywhere on the optomap. With integrated swept source OCT, the retina can be examined from vitreous through the choroidal-scleral interface. Images can be reviewed – remotely if required – via ‘OptosAdvance image management’ software and includes measurement and auto-montage capabilities.
Zeiss: Cirrus 6000
The Zeiss Cirrus 6000 OCT features a 100KHz light source allowing for 100,000 A scans per second and widefield HD imaging of the posterior and anterior sections of the eye. The fast and non-invasive device features FastTrac software to accurately track the patient’s eye and produces a 12mm HD raster 1-line scan to provide enhanced depth imaging of the choroid layer. It has inbuilt comprehensive analysis tools and algorithms for glaucoma management. The latest software features guided progression analysis, ganglion cell/inner plexiform analysis and a wellness report. The anterior segment premier module with easy-to-use attachable magnetic lenses allows for non-contact epithelium and pachymetry mapping of the cornea surface and anterior chamber dimensions. The Cirrus platform also ensures seamless transfer of patient data from previous generations of the device for continuity of patient care.
Optovue: iFusion80
Optovue’s iFusion80 combines the iVue80 SD-OCT system with the high resolution iCam12 12-megapixel fundus camera. The system now offers 80,000 A-scans per second – three times faster than the original model – offering improved efficiency and enhanced image quality. Increased scan patterns and a higher resolution offer clinicians increased confidence in the diagnosis of pathology. The device also offers an exclusive iWellness scan, which checks for both retinal disease and glaucoma, offering the patient further peace of mind. The system boasts a comprehensive range of anterior scans, including epithelial thickness mapping for the measurement of dry eye and vault mapping for those practices offering scleral lens fitting. The cost-effective modular system allows the user to purchase the iVue80 and the iCam12 individually, with the option to upgrade at any time, benefiting practices with smaller budgets.
Nidek: Retina Scan Duo 2
The updated Nidek Retina Scan DUO 2 (RSD 2) combined high resolution OCT and colour fundus camera (12 MP) benefits from high resolution 6x6mm macula and disc OCT-A with vessel density and perfusion density displays. Available from December, it features a retina map scan, incorporating macula and disc scans and colour fundus in one rapidly captured scan with an intuitive clinical data display. An automatic B-scan reduces noise to maximise scan resolution. The one-touch fully automated device provides exports for Opera and the Cues platform, sending OCT scans to the NHS referral service. An anterior module is included, while Navis 1.11 software provides a simple follow up with progression analysis and trend prediction for advanced diagnostic understanding. The RSD 2 produces 70,000 A-Scans per second and offers nine retinal scan patterns and four anterior scan patterns.
