MYOPIA
Smart, Data-Driven Myopia Management
The HBM-1 delivers a comprehensive approach to myopia management by visualizing changes in axial length (AL) and refraction over time. Longitudinal progression data is presented through intuitive graphs, while refraction (Rx) data transferred from Huvitz refractors can be integrated to support clinical decision-making. Clinicians can evaluate and present treatment outcomes, compare pre- and post-treatment changes associated with orthokeratology lens wear and surgical interventions, assess anisometropia, and offer more personalized patient consultations.
Axial Length Progression Analysis
Visualize changes in axial length and growth rates over time to gain a clear understanding of myopia progression and treatment effectiveness.
Ocular Growth Assessment Using Age-Based Growth Curves
Compare patient data against age-specific percentile growth curves to evaluate ocular growth patterns and assess the risk of myopia progression.
Personalized Myopia Management and Treatment Analysis
Track treatment history and duration while comparing changes before and after orthokeratology treatment. By evaluating anisometropia and lifestyle-related risk factors alongside progression data, the HBM-1 helps clinicians develop individualized myopia management and treatment strategies.
TOPOGRAPHY
Comprehensive Corneal Analysis in a Single Scan
Using Placido disc-based topography technology, the HBM-1 precisely measures a wide range of corneal parameters — including keratometry, keratoconus indices, Zernike coefficients, pupillometry, and White-to-White. Together, these measurements enable accurate assessment of corneal shape and visual quality, supporting contact lens fitting, early keratoconus detection, and both refractive and cataract surgery planning.
Accurate Keratometry and Comprehensive Corneal Assessment
Leveraging advanced Placido disc analysis technology, the HBM-1 provides the precise keratometry values (K1 and K2) essential for IOL power calculation. It also delivers comprehensive corneal maps and measurement data — including axial, tangential, refractive power, and elevation maps — enabling detailed evaluation of the entire cornea.

Immediate Contact Lens Fitting Evaluation
With its Fluorescein Image Filter, the HBM-1 simulates fluorescein patterns without applying fluorescein dye directly to the eye. This allows immediate evaluation of both hard and soft contact lens fitting, improving clinical efficiency and patient comfort.
Early Keratoconus Detection
The HBM-1 calculates the Keratoconus Prediction Index (KPI) to support the early detection and assessment of keratoconus, enabling timely clinical intervention and management.
Advanced Zernike Analysis
By analyzing Zernike coefficients and maps, the HBM-1 delivers a systematic evaluation of higher-order aberrations, refractive variations, and irregular astigmatism. This comprehensive analysis supports a deeper understanding of visual quality and corneal optical performance.
DRY EYE
A Three-Step Diagnostic Workflow — OSDI · Advanced Examination · Integrated Reporting
The HBM-1 offers a structured approach to dry eye assessment, beginning with the globally recognized OSDI questionnaire to quantify patient-reported symptoms. Advanced examinations follow — including non-contact tear film stability assessment via NIBUT, lipid layer imaging, quantitative tear meniscus height analysis, and meibomian gland function grading. The objective data gathered from both the questionnaire and clinical examinations supports differential diagnosis, treatment planning, patient counseling, and long-term record management.
STEP01
Enhanced Diagnostic Efficiency with the OSDI Questionnaire
The Ocular Surface Disease Index (OSDI) is a standardized questionnaire widely used to evaluate dry eye symptoms. It enables quantitative assessment of patient-reported symptoms and supports multiple languages, helping improve diagnostic efficiency while providing consistent evaluation criteria across diverse clinical settings.
STEP02
Comprehensive Evaluation Through Four Advanced Diagnostic Assessments.
Meibomian Gland Dysfunction Assessment Through Visual Grading
Meibomian gland function can be visually evaluated and graded, providing valuable insight for identifying the underlying causes of dry eye disease and establishing appropriate treatment strategies.
Evaporative Dry Eye Assessment Through Inter-Blink Interval Analysis
The Inter-Blink Interval (IBI) is measured to evaluate blinking patterns. Results are presented as quantitative indicators of blink frequency and regularity, supporting dry eye assessment and lifestyle-related patient counseling.
Evaporative Dry Eye Assessment Through Inter-Blink Interval Analysis
Tear film stability is evaluated using a non-contact method, with areas of tear film breakup tracked in real time. The results provide quantitative visualization of both the timing and extent of breakup.
Tear Meniscus Height Analysis for Tear Volume Assessment
Tear meniscus height is quantitatively measured to objectively assess tear volume. The tear meniscus can be clearly visualized along the eyelid margin and accurately measured using the built-in caliper tool. Once the measurement points are selected, the tear meniscus height is calculated automatically.
STEP03
Integrated Analysis for Personalized Treatment Strategies
The Dry Eye Report consolidates the results of every assessment category — including NIBUT, Fluorescein Imaging, Lipid Layer Analysis, Tear Meniscus Height, Meibography, Blink Analysis, and OSDI — into a comprehensive, structured report optimized for diagnosis, treatment planning, and patient communication.
User Convenience
Network in Huvitz Integrated Image Server (HIIS-1)
Comprehensive Reports for Reliable Clinical Evaluation
The HBM-1 generates structured reports that present predicted IOL power alongside key data from Biometry, Topography, Myopia, and IOL analysis, supporting reliable clinical evaluation and decision-making.
Visual and Voice Guidance for Enhanced Patient Comfort
To improve patient comfort during examinations, the HBM-1 provides visual and voice guidance that indicates when patients should open or close their eyes throughout the measurement process.
To improve patient comfort during examinations, the HBM-1 provides visual and voice guidance that indicates when patients should open or close their eyes throughout the measurement process.
• Measurement Start Notification (Single Beep): Indicates when the patient should open their eyes.
• Measurement Completion Notification (Double Beep): Indicates when the patient may close their eyes.
Auto Tracking for Enhanced Accuracy and Reduced Measurement Errors
The automatic focusing mechanism continuously tracks the measurement target, eliminating the inconvenience of manual focusing while enabling faster, more accurate measurements. An Auto Tracking guide also provides directional cues for joystick and chinrest adjustments, helping operators position patients more efficiently.
Integrated PC Architecture for Space and Cost Efficiency
With its integrated PC architecture, the HBM-1 eliminates the need for an external computer. Every function — from measurement and analysis to report generation — runs directly on the built-in 10.1-inch touchscreen LCD, helping save both workspace and installation costs.
