Greater Insight: See more details below the surface

Supplement your microscope view with bright, sharp imaging of previously hidden subsurface tissue details. Intraoperative integration of OCT imaging provides you with additional information so you can get greater insights into ocular pathology during surgery.

  • Clearly differentiate between artifacts and tissue due to the unique spectrometer technology with dispersion compensation software and a highly sensitive detector that captures more signal
  • See fine details even through blood in trauma cases thanks to an axial resolution of 2.4 μm in tissue
  • Capture comprehensive area scans with high lateral resolution, due to a high scan density of up to 1000 A-scans x 1000 B-scans to not miss out on an important detail
  • Playback through acquired OCT scans frame by frame or in video mode to check e.g. if there is residual sub-retinal fluid, if the positioning of the glaucoma drainage device is correct, or if the corneal graft is well opposed to the host cornea.

Greater insight: Get a wider view

Ensure you have a full view of the surgical field so you don’t miss features at the periphery. EnFocus provides a 20 x 20 mm lateral field of view even at high magnification.

No need to adjust the viewing perspective during surgery. This enables you to monitor any changes at the periphery even when working in the center of the eye.

EnFocus offers wide scans, that cover the whole cornea and the anterior chamber – detail and resolution are impressive and allow a thorough visualization of anterior segment details. EnFocus provides a remarkable insight into the third dimension, meaning the vertical axis Z.

Greater insight: Clinical assessment to intraoperative decisions

Bridge the gap between pre-operative assessment and real-time evaluation of changes to tissue microstructures during surgery with EnFocus OCT.

In a clinical setting, OCT has become the standard of care with clinical OCT imaging such as Envisu C2300. OCT imaging systems are now moving more and more into the operating rooms where they are impacting surgical decision-making. The DISCOVER Study* collected data on the impact of  intraoperative integration of OCT . The study showed that microscopes with OCT provide additional information and can consequently change the surgical plan intraoperatively. In membrane peeling procedures the study showed that intraoperative OCT findings were discordant from the surgeon's initial impression in 35% cases.

Benefits for your retina surgery

Use OCT to assess the level of tension in a membrane peel in real time, in order to avoid potential tears and protect the integrity of underlying tissue. A high-resolution view of <=4 µm also aids examination of retinal morphology for residual membranes and complications such as macular holes, or sub-retinal edema.

Additional benefits for posterior surgery include:

  • Dynamic scan control via footswitch for swift adjustment of the scan angle to align with the membrane tissue
  • Easy integration of fundus viewing systems such as the BIOM5 from OCULUS with synchronized focus

Benefits for your cornea surgery

Easily view the entire anterior segment with the EnFocus Ultra-Deep system which has an increased depth of up to 11 mm.

In advanced lamellar corneal surgeries such as DMEK (Descemet's Membrane Endothelial Keratoplasty) and DSEAK (Descemet’s Stripping Endothelial Automated Keratoplasty), this aids the surgeon in confirming the correct orientation of donor tissue which may help avoid corrective follow-up surgery.

Benefits for your glaucoma surgery

OCT scans of up to 20 mm wide and 11 mm deep support your view to aid accurate placement of an XEN gel stent.

OCT can also support shunt vessel placement and assessment of how much the tube should be tied off to control intraocular pressure. This can prevent further progression of the glaucoma.

Immediate confirmation: Observe & respond to tissue changes

The EnFocus intraoperative OCT imaging system provides real-time confirmation of how ocular tissue is reacting to your surgical maneuvers. You can immediately adjust your surgical plan if needed for greater confidence in the surgical outcome.

Observe real-time tissue reaction and respond instantly

  • Real-time display of 30 fps provides immediate feedback at each step e.g. to verify adherence of donor tissue in DMEK or DSAEK surgery
  • If OCT reveals a complication which wasn’t visible via the microscope view, for example due to bleeding, you can instantly adapt your surgical plan
  • For additional verification you can easily review or playback through the acquired scans frame by frame or in video mode
  • Live on-screen measurements provide even more information e.g. cornea thickness and needle depth during DALK surgeries

Maximum Freedom: Smooth independent workflow

EnFocus built into the Proveo 8 supports your workflow and enables you to independently control your OCT view. You are free to concentrate on your procedure.

  • Easily activate intraoperative OCT yourself at any point during surgery via footswitch, handle, or 27” touchscreen HD monitor
  • Preprogram your personal settings and modes before surgery according to surgery type and step then allocate to the footswitch or handle for a smooth workflow
  • Record or capture images in the same way, choose the Evolution4K recording system from Med X Change for comprehensive documentation
  • View your microscope and intraoperative OCT-image in the eye pieces via the DI C800 or on the 27” HD touch-screen monitor and for even larger screen projections, four video outputs are available

Workflow Freedom in the Operating Room

Hear from vitreoretinal surgeon Dr. Barbara Parolini, Eyecare Clinic Brescia, Italy about the freedom that the EnFocus imaging systems OCT provides in the OR.

Maximum freedom: OCT imaging system, with intuitive gesture control

No need to interrupt surgery or rely on a technician to acquire an optimal OCT image thanks to automated functions and intuitive touch-screen operation.

You can activate automatic image optimization with just a tap of the footswitch, handle or touch screen. Brightness and sharpness of the image is adjusted for you, so you can rest assured that you always have an optimal OCT image. The Auto Locate function centers the OCT image automatically. Location lock in the z-direction then ensures the image remains centered throughout your procedure. Its just as easy to adjust scan pattern, scan size and scan density.
