OCT: From 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. OCT technology is now moving more and more into the operating room where it is impacting surgical decision-making. The DISCOVER* study using EnFocus showed that "in membrane peeling procedures, intraoperative OCT findings were discordant from the surgeon's initial impression in 35% cases"

Ehlers, M.D. as Principal Investigator.

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.

EnFocus Ultra-HD OCT: Rich subsurface detail

The best images matter. EnFocus Ultra-HD OCT technology delivers high definition real-time images of both the posterior and anterior segment.

Enfocus Intrasurgical OCT features:

  • Resolution: ≤ 4 μm
  • Depth: 2.5 mm image depth in tissue
  • High OCT scan density (up to 1 million A-scans per volume)

EnFocus Ultra-Deep OCT: Deeper & wider

The EnFocus Ultra-Deep OCT option delivers very deep and wide imaging for full anterior segment visualization. Anterior structures continue to be resolved with crisp detail of ≤ 9 μm making it an ideal option for glaucoma surgery.

Enfocus Intrasurgical OCT features:

  • Resolution: ≤ 9 μm
  • Depth: 11 mm in tissue
  • > 20 mm scan length
