HTG-1 offers an integrated evaluation of corneal topography and dry eye diagnosis in a single device, allowing for an accurate assessment of overall eye health. Through precise corneal diagnostics and tear film analysis, it identifies underlying causes, aiding in the prevention and treatment of corneal diseases and dry eye syndrome while helping maintain visual acuity. Additionally, it supports long-term visual health through pre- and post-operative management.
Utilizing Placido disc-based analysis technology, HTG- 1 precisely measures detailed corneal parameters such as curvature and shape, pupil size and response, refractive power variations, and corneal diameter. The highly reliable data can be widely applied across various clinical fields, including early detection of keratoconus, analysis of visual distortion, preoperative assessment for refractive surgery, and lens prescription and fitting.







HTG-1 performs a multi-faceted diagnosis of dry eye syndrome based on various indicators, including tear secretion evaluation, tear film stability assessment, meibomian gland dysfunction analysis, tear film distribution diagnosis, tear film color and pattern evaluation, blink interval measurement, corneal and conjunctival redness grading, and the OSDI self-assessment questionnaire. Its non-contact precision measurements and visualized reports enable accurate cause analysis and personalized treatment planning.
With a 90-degree left-right rotating LCD, foot switch, wide headrest, auto-tracking, and sound guidance, HTG-1 offers an optimal examination environment that enhances operator convenience. The built-in PC enables seamless monitoring of the entire process—from measurement to analysis reports — for accurate evaluation. Compatibility with HIIS-1 and DICOM further improves clinical efficiency.
