Huvitz HDA-100 Ocular Surface Analyzer

HDA-100 Ocular Surface Analyzer | Coburn Technologies, Inc.

Integrated System for Ocular Surface Analysis

The HDA-100 ocular surface analyzer analyzes the ocular surface for the diagnosis and treatment of dry eye disease (DED). Featuring 16 different measurements and tests, it offers five million pixel image resolution, single and multi-shot video capabilities as well as two cones (main and placid) tests such as interferometry and tear meniscus. All layers can be analysed – lipid, aqueous and mucin – as well as the upper and lower meibomian glands when identifying dry eye disease.

The HDA-100 gives optometrists a much better view of how to treat dry eye disease with specific treatments such as quantum molecular resonance or eye drops.

– 16 different tests and measurements to diagnose dry eye disease
– Quick and easy analysis of the tear film to investigate tear composition
– All layers can be analysed including the upper and lower Meibomian glands
– Single and multi-shot video capabilities
– 2 cones (main and placid) for tests such as interferometry and tear meniscus
– 4 minute diagnostic time


Complete meibo analysis of structure and secretion view, including auto detection of maximum thickness of the Lipid layer, average thickness, and blinking rate

Tear Meniscus Measurement


The thickness of the tear meniscus that is observed on the eyelid margtins provides useful information on the tear voume. The height, regularity, and shape of the tear meniscus can be examined.

Auto-NIBUT (Non-invasive Break Up Time)

Through the Placido rings, HDA-100 automatically provides first BUT, average BUT, stability graph, and tear topography

Meibography & 3D Meibomian Gland Imaging

Meibography and 3D meibomian gland imaging. Auto length and width with loss area percentage. 3D images.

Can detect the length and width of meibomian glands shown through infrared meibography without requiring input from the user

Other possible examinations include an assessment of grading scales for meibography images, white-to-white measurement, bulbar redness classification, blepharitis and cylindrical dandruff testing, and pupillometry.
