Canon Xephilio OCT-A1 Optical Coherence Tomography

The Xephilio OCT-A1 is Canon’s Optical Coherence Tomography for the in-vivo imaging and measurement of the retina, retinal nerve fiber layer, and optic disc. For outstanding performance and exceptional ease of use you can rely on every day, look no further than Xephilio OCT-A1. Superior image quality and a host of automated features optimize and simplify your examinations, while the system’s high scanning speed enables short examination times, increasing your efficiency and your patients’ comfort.


Outstanding Imaging

Xephilio OCT-A1 offers superb image quality. With a digital resolution of up to 1.6 μm, the system enables excellent differentiation of structures and individual layers of the retina. The high scanning speed of 70,000 A-scans/s enables very short examination times of usually about two seconds, resulting in less motion artefacts and increased patient comfort.

High-definition imaging

Xephilio OCT-A1 offers excellent native optical resolution. In combination with the averaging of multiple scans (up to 200) excellent image quality with amazing detail resolution can be achieved.

Accurate scanning, outstanding ease of use

The system’s integrated Scanning Laser Ophthalmoscope (SLO) contributes significantly to scan quality and ease of use. By providing real-time retinal tracking, it enables accurate monitoring of the examination.

Fast and precise follow-up

The SLO also enables accurate follow-up examinations by automatically adjusting to the same scan position as used in the previous exam. For reliable comparison, the software automatically selects identical scan parameters.

Automatically achieve consistently high image quality

At times, involuntary eye movement during examinations are unavoidable. With its integrated SLO real-time retinal tracking technology the system’s allows you to maintain the exact same scanning position automatically. As a result, Xephilio OCT-A1 retinal tracking greatly reduces movement artefacts and thus provides consistent, high image quality.


High definition, enhanced depth, wide field of view

With Xephilio OCT-A1, you can average up to 200 scans to achieve an image resolution that allows you to see in detail both the layer structure as well as the vitreous pleated structure. For optimal imaging, the system offers special scan modes for vitreous and choroid imaging, as well as a particularly wide scan width of up to 13 mm


Reliable 10 layer recognition

Canon’s Xephilio OCT-A1 can automatically detect and distinguish 10 layers of the retina – including Bruch’s membrane (BM) – thanks to its excellent image quality and resolution.


Fast and Easy Acquisition with Incredible Detail

Examinations with the Xephilio OCT-A1 are extremely simple and therefore easy to delegate. A complete range of intelligent functions enables fully automated examinations. The auto-re-scan function intervenes if a patient makes unwanted eye movements and automatically compensates for any artefacts.

Automated anterior tracking

After pointing approximately to the center of the pupil, the system automatically detects and maintains the exact center, even when the patient is moving his eye or blinks.


Automatic image optimization

Afterwards, the built-in auto focus and C-gate functions will automatically determine the highest signal quality for the best possible examination results.


Real-time retinal tracking

By detecting and compensating movements in the fundus images on a frame-by-frame basis the impact of small involuntary movements is reduced during fixation and motion artefacts greatly reduced.



Xephilio OCT-A1 offers ten fixed and freely programmable exam presets, allowing you to combine multiple scan modes into a single exam. Using presets can help you improve the workflow and consistency of exams and, at the same time, increase patient comfort.

Versatile reporting possibilities, extensive normative databases

Xephilio OCT-A1 provides you with a full range of reporting tools, including the relevant normative databases. Thanks to its extensive DICOM and EMR capability, results from multiple Canon imaging modalities can be stored, shared and analyzed as needed in your daily practice.



The system provides a detailed analysis of retinal thickness using comparisons with normative databases, ETDRS grids, various tables and 3D visualizations.



Early detection is the key to slowing the progression of glaucoma. Xephilio OCT-A1 supports NFL + GCL + IPL and GCL + IPL measurements with a wide set of graphical representations for complete analysis.


Combined Report

By sharing the same database with an optional retinal camera, fundus images can be easily integrated into the OCT evaluation. Fundus and OCT images can be displayed side by side or mapped and superimposed as needed.


Optic Disc

Xephilio OCT-A1 allows a comprehensive analysis of all optic disc parameters, including comparisons with an extensive normative database.


Progression report

Analysis results comparing five examinations arranged in time sequence of eyes on the same side in the same scan mode, and same size of scanning area.


Anterior Segment Analysis

With the optional Anterior Segment Adapter ASA-1, Xephilio OCT-A1 also gives you the ability to analyze and document the anterior segment of the eye during the same exam. The included measurement package allows you to quantify standard parameters quickly and easily.


The corneal thickness analysis on Xephilio OCT-A1 is presented as maps of corneal thickness and epithelium thickness including corneal grids, as well as numerical table.


The anterior segment analysis kit allows you to measure the distance between two points, arbitrary angles, a well as AOD (Angle Opening distance) and TISA (Trabecular Iris Space Area) values.


New Retinal Imaging Reality

Along with the newly introduced physical distancing protocols to prevent the spreading of COVID-19, patient examinations have turned impossible for most ophthalmic diagnostic devices. However, with the Canon Xephilio OCT-A1, there are multiple possibilities to operate the device in a completely safe way.


Retinal Imaging Control Software

Software designed to work with all Canon retinal cameras and OCT; for capturing, reviewing and reporting. When the camera is used stand-alone, it also functions as database with an archive function.

Extremely intuitive user interface. Clear graphic representation of functions and display of previous studies.


Displays images of the same side eye to compare them. Or select studies from previous dates to monitor progression.

Observation progression: select up to 5 past examinations to see changes over time.


Report screen with extensive software tools: embossing a retinal image, changing gamma value, brightness and contrast, color balance balance, adding annotations  and measuring C/D ratio.


EMBOSS can be useful to enhance the topography of the retina in the evaluation of macular degeneration, glaucoma, and retinopathy.


Emboss Negative

This function will make the blood vessels stand out.


Emboss Positive

The optic disc stands out.



Inverts the color of an image to assist diagnosis.



Overlay 2 images to see differences and changes in pathology. Selected images are aligned automatically. It can be useful for comparison to see changes, but also the colour image could be overlayed with e.g. a FAF image for additional information.



Add shapes, lines, arrows and comments to a captured image.


CUP/DISC Measurement

Measure the optic nerve papillary area. The C/D can be measured as line or area ratio.


Canon Opacity Suppression

When obtaining retinal images, ocular opacity can cause several problems: the scattering of the light will make the edges of the blood vessels appear blurred, the difference in brightness of the retina will be reduced, making it very difficult to distinguish between structures. Furthermore a cataract eye will cause images to appear more yellow. Canon opacity suppression tool is a unique and sophisticated software tool, that based on the full information from the CMOS sensor of the digital camera,  will largely suppress the effect of ocular opacities on color images.


Our retinal cameras can be combined with a Canon OCT, using the same software and sharing the database. Output of both devices can be combined in one report to facilitate a comprehensive analysis.
