Intraoperative OCT launched internationally at WOC
TOKYO — Carl Zeiss Meditec launched internationally at the World Ophthalmology Congress the Rescan 700 optical coherence tomography system integrated in the Opmi Lumera 700 surgical microscope for intraoperative use.
Susanne Binder, MD, who was involved in the development of the device and has been using a prototype for her surgery since 2008, has now treated more than 50 patients with the Rescan since November 2013.
Intraoperative OCT, she said, allows transparent structures to become visible during surgery. A very fine pre-retinal membrane can be visualized without the use of dyes.
“You can see where the membrane is, very adherent or bridging the retina, and you can safely remove it, finding the exact place where you can start grabbing it without causing trauma,” she said at an industry-sponsored symposium.
Intraoperative OCT also helps the surgeon to make decisions in the course of procedures.
“While you are removing membranes, you can see how much traction you are causing on the retina. If there is a small macular hole and there is a risk of enlarging it with your maneuvers, you can see it, and you may want to change your instruments, using scissors instead of forceps, to cut the membrane and leave the roof of the hole intact,” she said.
The Rescan can be used for posterior and anterior segment surgery.
“The more we use, the more we learn about new pathologic relationships during surgery,” Binder said.
