2 in 1 Ocular Diagnostic Master
The Pathfinder is an advanced multi-purpose corneal topographer designed to streamline dry eye diagnostics and corneal topography analysis. Featuring a built-in computer, it maximizes exam room efficiency while integrating essential diagnostic capabilities. Its user-friendly design enhances doctor-patient communication with easy-to-understand visual reports and real-time observation via external display connection. The ergonomic 50° adjustable display, intelligent auto eye recognition, and compact cone ensure precise operation and adaptability. With versatile clinical applications, including dry eye analysis, corneal morphology diagnosis, aberration simulation, and lens fitting, the Pathfinder is an indispensable tool for modern ophthalmic care.

Dry Eye QuestionnaireOcular Surface Disease Index (OSDI)/McMonnies/SPEED/DEQ 5 The built-in dry eye questionnaire is designed according to the risk factors and clinical characteristics of dry eye. It offers a simple preliminary dry eye assessment, enhancing diagnostic accuracy, treatment efficiency, and patient follow-up care. |

|
Non-Invasive Breakup TimeInterface - Comprehensive dry eye examinations. NIBUT - More than 9.6 mm diameter Placido ring projection. Auto-identify the breakup area and analyze NIBUT intelligently. |
|
|
Meibomian Glands Function Evaluation
Auto-identify and auto-enhance meibomian gland images Automatically analyzes meibomian glands loss caused by dysfunction of the meibomian glands, providing accurate and quantified diagnostic results. |
|
|
Non-Invasive Tear Meniscus HeightAutomatic identification system depicts tear meniscus area and measures the tear height intelligently. |
|
|
Conjunctival Redness AnalysisIdentify and calculate percentages of conjunctival congestion, ciliary congestions, and evaluate severity of eye congestion. |
|
Lipid Layer ThicknessMonitor the dynamic lipid layer and its distribution through video recordings compared to standard templates, aiding in the assessment of MGD. |
Eyelid MarginThe high-resolution image allows for zooming, enabling detailed examination of the overall shape of the eyelid margin and subtle changes. |
|
Blink QualityHigh-definition video is captured with an infrared light source and automatically analyzes blink frequency, blink interval, incomplete blink, and incomplete blink ratio. |
Corneal Fluorescein StainingThe specially designed built-in yellow filter, combined with cobalt-blue illumination, enhances the contrast of corneal fluorescein staining images, effectively increasing the detection rate of early corneal epithelial staining. |
|
Fluorescein Tear Film Breakup TimeAI technology automatically detects changes in tear film morphology and calculates tear film breakup time to assess tear film stability. |

Corneal Topography
Lens Fitting
A simulated fluorescein image will be created based on patient’ s cornea. The system will recommend several suitable lenses to choose, which accelerates the workflow and excludes unfit lens to save the trouble for patient to do real several fluorescein staining.
Aberration & Simulation
Zernike wavefront aberration analysis visualizes cataract and refractive surgery planning, ensuring optimal postoperative vision quality for patients.
Maps
Maps provide Sagittal Curvature,Tangential Curvature, Elevation Map, Refractive Power, K1/K2/Km/Astig/Ecc value, and more!
