ZEISS Launches ALTA DUO 300 for Automated Multimodal Retinal Imaging

ZEISS Medical Technology has expanded its ophthalmic diagnostic range with the introduction of a multimodal imaging platform designed for primary eye care practices, clinical workflows, and high-volume retinal screening environments. The compact system integrates automated optical coherence tomography and digital retinal photography into a unified footprint, expanding the medical technology company's existing diagnostic portfolio alongside established imaging platforms.

Diagnostic Modalities and Automated Clinical Workflow
Clinical retinal assessment routinely requires multiple diagnostic steps, including structural cross-sectional scanning, vascular microcirculation tracking, and surface photographic documentation. The new hardware architecture integrates four specific diagnostic functions within a single automated platform: structural optical coherence tomography supported by normative reference databases, true-color fundus photography, artificial intelligence-assisted optical coherence tomography angiography, and full anterior chamber depth scanning that operates without requiring auxiliary attachment lenses.

Automated alignment, focusing, and image acquisition reduce manual positioning demands on clinical operators, establishing consistent cross-patient documentation standards across varying clinical skill levels. Combining anterior and posterior segment assessment within one optical pathway eliminates the clinical need for patient repositioning across separate diagnostic stations, thereby reducing examination cycle times in routine ophthalmic consultations. The technical configuration will be presented at the European Society of Retina Specialists congress in Vienna, Austria, held from October 1 through October 4, prior to commercial rollout in designated markets during 2026.

Multimodal combined systems represent a distinct category in ophthalmic instrumentation, characterized by the integration of spectral-domain optical coherence tomography and fundus photography into a single automated housing. Comparable industry benchmarks include the Topcon Maestro2, which pairs automated 3D spectral-domain optical coherence tomography operating at approximately 50,000 axial scans per second with a 12-megapixel color fundus camera, and the Canon OCT-HS100 series. Higher-end non-automated or specialized multimodal systems, such as the Heidelberg Engineering SPECTRALIS platform, utilize scanning laser ophthalmoscopy combined with modular spectral-domain imaging at acquisition speeds reaching 85,000 to 125,000 axial scans per second, primarily addressing specialist surgical centers and academic research clinics.

Automated multimodal devices typically operate within the standard 840 nm to 880 nm central wavelength range for posterior segment structural scanning, providing axial resolutions between 5 and 7 micrometers in tissue. Incorporating automated optical coherence tomography angiography and integrated anterior segment optics within an automated desktop chassis lowers footprint demands and capital investment relative to acquiring dedicated standalone angiography platforms, making comprehensive vascular screening accessible to non-tertiary outpatient settings.
