Heidelberg OPERA, with next-generation swept-source intraoperative OCT, seamlessly integrates real-time cross-sectional imaging into the surgical workflow.
Heidelberg OPERA with iOCT ushers in a new era of image-guided surgery by revealing anatomical structures beneath the tissue surface that cannot be seen through microscopy alone.
Bringing diagnostic quality OCT imaging into the OR
Integrated iOCT extends the view beyond the visible surface, helping surgeons to assess tissue configuration, confirm anatomical relationships, and guide delicate surgical maneuvres in real time. As digital surgery continues to evolve, Heidelberg OPERA provides a platform for future innovations such as image-guided workflows, quantitative intraoperative measurements, and intelligent surgical assistance.
The high-speed swept-source iOCT engine operates at 1060 nm, delivering real-time cross-sectional imaging at 70,000 A-scans per second. The longer wavelength provides excellent penetration through ocular tissues while enabling visualization of both anterior and posterior segment anatomy. High axial resolution reveals fine structural detail, while rapid image acquisition and smooth real-time display provide immediate feedback throughout the procedure, supporting informed surgical decision-making.
