Carl Zeiss Meditec launches new OCT applications for eye surgery

9 April 2009

Carl Zeiss Meditec has launched new optical coherence tomography (OCT) applications to support cataract, refractive, glaucoma and retina procedures.

The Carl Zeiss Cirrus HD-OCTThe newest version of Cirrus HD-OCT 4.0 adds critical features to support cataract and refractive surgeons as well as advanced analyses for tracking change in glaucoma and managing retina disease. Cirrus 4.0 software has been released internationally and is pending FDA clearance in the US.

  •  Anterior Segment Imaging provides visualization of the cornea and angle with central corneal thickness measurement for glaucoma management. No external lenses are needed;
  •  Normative RNFL and Macular Thickness Data allows physicians to identify pre-existing glaucoma and retinal disease and to rule-out suspected glaucoma;
  •  Guided Progression Analysis (GPA) software supports glaucoma treatment decision making by identifying statistically significant RNFL thickness changes; and
  •  Macular Change Analysis helps physicians evaluate retinal status and response to therapy by mapping changes in macular thickness measurements.

Cirrus HD-OCT 4.0 is aimed at practices that rely on advanced technologies to identify pre-existing eye diseases, to closely monitor disease progression and to determine the most appropriate course of treatment for each patient. The new software technologies can be seamlessly integrated onto any Cirrus HD-OCT platform.

β€œSince we first introduced OCT technology to the ophthalmic industry nearly fifteen years ago, we have continued to invest in applications that leverage clinical and scientific advances in the field as well as features that make the technology itself more efficient and user-friendly for practitioners,” said Michael Kaschke, President and Chief Executive Officer of Carl Zeiss Meditec.

"Cirrus is a valuable tool in my practice for both my cataract/ refractive surgery and glaucoma patients,” said Ike K Ahmed, MD, FRCSC, Assistant Professor at the University of Toronto and Clinical Assistant Professor at the University of Utah in Salt Lake City. β€œIt helps me to identify potential problems in my pre-operative cataract/refractive workups and my patients more easily understand what they can expect post-operatively."

The Stratus OCT 6.0 upgrade includes the following enhancements:

  •  Anterior Segment Imaging is also available for Stratus OCT and is currently pending 510k approval within the USA.
  •  Enhanced Repeat Function simplifies image registration across visits to enhance reproducibility.
  •  Multi-slice reports provide an overview of the entire retina on a single page, allowing clinicians to preview all B-scans at-a-glance. This functionality is especially suited for cataract pre-op assessment and it allows physicians to set appropriate post-surgical expectations with patients.

These new features for Stratus OCT, combined with GPA software, provide more diagnostic functions than ever before. Version 6.0 is especially applicable to comprehensive ophthalmologists that require a consistent, cost-effective platform to identify and monitor cataract patients with pre-existing glaucoma or retina diseases.
