Precise Capture of Microstructural Changes

With exceptional clarity, the system detects subtle morphological anomalies such as cystoid macular edema (CME), dome-shaped elevations, and early detachments of the RPE layer. This precision enables early and accurate assessment of lesion structure and progression, supporting timely diagnosis and effective treatment planning.

The Angio Enhancement package for the HOCT-1 (80) increases performance and reliability by combining location-sensitive scan speed improvements with real-time retinal tracking via a 30 fps IR camera. Image quality is optimized through vascular signal contrast across slabs and foveal reflex suppression, along with post-acquisition B-scan registration, which restores disrupted vessels.

CNV visualization benefits from an advanced despeckling system that highlights only true neovascular structures. Robust noise controls eliminate motion artifacts, reduce horizontal banding, and remove ghosting, while the PAR (Projection Artifact Removal) function clears superficial vessel shadows and enhances outer retinal definition. Finally, refined retinal layer segmentation delivers more accurate OCTA analyses, increasing diagnostic confidence.

Real-Time Retinal Tracking

The HOCT-1 (80) offers precise visualization of the retinal microvasculature through real-time retinal tracking with a 30 fps IR camera that corrects eye movements during acquisition. By reducing motion blur and suppressing banding artifacts, it preserves vascular continuity and sharp capillary edges, producing stable and accurate OCTA images even with slight fixation movements or blinks — enabling clearer data capture with fewer retakes.

Higher Signal Contrast in CNV

The HOCT-1 (80) improves the visibility of choroidal neovascularization (CNV) in the outer retina by optimizing signal processing within the selected OCTA slab, suppressing foveal specular reflections and reducing noise. The result is higher contrast between vessels and background, with preservation of microvascular continuity, a cleaner representation of fine capillaries, and more reliable delineation of CNV networks, improving detection, edge assessment, and comparison in follow-up.

Motion Artifact Removal

The HOCT-1 (80) minimizes motion-related artifacts in OCTA by correcting micro eye movements during acquisition and applying a dedicated “fringe noise” reduction algorithm that suppresses horizontal banding. The result is cleaner slabs with preserved vascular continuity, sharper capillary edges, and reduced background noise, delivering more readable images and reducing the need for repeated scans.

Projection Artifact Removal (PAR)

The HOCT-1 (80) uses PAR to suppress shadow-like projections from the superficial vascular plexus that contaminate deeper OCTA slabs. By eliminating these projection artifacts, the system preserves true flow signals in the outer retina, enhances vasculo-fundic contrast, and maintains microvascular continuity. The result is a cleaner and more accurate visualization of structures such as NVC, with sharper edges and fewer false positives, leading to more precise interpretation and more reliable follow-up quantification.

Enhanced Retinal Layer Segmentation (RPEDC)

The HOCT-1 (80) offers more precise layer segmentation, with special improvements in the RPE/Bruch’s membrane complex. Its refined algorithm reliably tracks the RPEDC boundary even in irregular morphologies, reducing manual corrections and increasing reproducibility. By clearly separating the outer retinal layers, it enables better visualization of sub-RPE structures, enhanced detection and delineation of drusen/PED, and more reliable thickness and en face maps. The result is consistent layer selection and greater diagnostic confidence in the assessment of subtle RPEDC changes over time.

OCT Topography simultaneously captures the anterior and posterior surfaces of the cornea, generating a detailed 3D analysis with 16 types of corneal maps for precise evaluation of thickness, curvature, and elevation.

Maps and Numerical Data on a Single Screen

On a single screen, the user can visualize four maps — Axial, Anterior Elevation, Posterior Elevation, and Pachymetry — while analyzing important parameters such as SimK, Meridian, Keratoconus Index, and epithelial thickness. In addition, it is possible to switch between maps or adjust the display layout as needed, enabling flexible use tailored to different diagnostic scenarios.

Simplified clinical workflow

Analysis screens can be printed or sent to a PACS server in DICOM format, facilitating the storage and exchange of results. When printing, the background can be changed to white to improve report readability. Integration with the EHR and hospital PACS further streamlines the clinical workflow.

Complementing Topography, Optical Biometry visualizes the entire axial length — from the cornea to the macula — in high-resolution 2D images, offering far more detail than conventional ultrasound. Together, these technologies provide the detailed data needed for personalized intraocular lens (IOL) selection and safe surgical planning.

Fast, Precise, and Highly Reliable Measurements

With Burst Mode, the system performs rapid consecutive measurements — three times for axial length and five times for central corneal thickness (CCT), anterior chamber depth (ACD), and lens thickness (LT) — ensuring high consistency and accuracy. Low-quality readings caused by blinking or minor movement are automatically filtered out, ensuring reliable IOL calculations.
