Surgical Microscope Reveals Transparent Ocular Structures

A new microscope provides ophthalmic surgeons high quality intraoperative optical coherence tomography (OCT) visualization of the eye, without interruption of surgery.

The OPMI LUMERA 700 microscope for cataract and retina surgery is provided with stereo coaxial illumination (SCI) technology and optics that allow visualization of minute details. The system also integrates ZEISS RESCAN 700 for use during surgery in the anterior and posterior segment of the eye, with a broad range of potential applications. The high definition, continuous OCT images add a real time third dimension directly in the eyepiece, providing surgeons with unprecedented views below the surface of the surgical field and enabling them to see more, including transparent structures in the anterior and posterior segment of the eye.

In addition to SCI illumination, the OPMI LUMERA 700 boasts numerous features, such as an integrated keratoscope, a fluorescent filter to inspect incisions, and DeepView, a depth of field management system that can switch from maximum light transmission to maximum depth of field at the touch of a button. The system also includes built-in ultra violet (UV), infrared (IR), and blue blocking filters plus a retina protection device, all of which are available for all three light sources. When used in combination with CALLISTO eye, the OPMI LUMERA 700 also offers innovative tools such as Z ALIGN, which assists in aligning toric intraocular lenses (IOLs).

The RESIGHT 700 fundus viewing system allows the retinal surgeon to clearly recognize every detail of the retina. Working together seamlessly, the OPMI LUMERA 700 microscope reacts to RESIGHT insertion by automatically adjusting the camera settings, invertertube settings, lighting, and speed of motion to the correct values for retina surgery. System settings can be saved for individual workflow steps in the surgery and activation during surgery by using the foot control panel. Switching between RESIGHT and the microscope image is simple, as both systems use the same focal plane. The OPMI LUMERA 700 microscope is a product of Carl Zeiss Meditec (Jena, Germany).

“The first positive experiences surgeons made with our new intra-operative OCT confirmed our approach to merge two of our gold standards into one system. By doing this we now are able to support our customers even better to improve patient outcomes,” said Ludwin Monz, president and CEO of Carl Zeiss Meditec. “The possibilities of how this new visualization technology will change ophthalmic surgery and expand the capabilities especially for retina and cornea surgeons are now just beginning to be realized.”

“It is amazing - you suddenly see things that you have never seen before”, said Prof. Oliver Findl, MD, MBA, of Hanusch Hospital (Vienna, Austria). “For me, the new device from ZEISS is something I really wouldn’t want to miss anymore. With ZEISS OPMI LUMERA 700 and RESCAN 700 we learn a lot of things to enhance our own performance.”
