Meibomian Glands Function Evaluation

Automatically anlalyze meibomian glands loss caused by meibomian glands dysfunction with precise and quantified diagnosis results

Auto identify and auto enhance of meibomian glands area

Automatic identification system depicts tear meniscus area and measures the tear height intelligently.

Lipid Layer Thickness

Observe lipid layer dynamic and distribution by video recording compared with standard templates. It’s helpful for judging MGD.


Eyelid Margin

The high resolution image supports zoom in to meet examination requirements of overall shape of eyelid margin and its slight change.


Cornea Sodium Fluorescein Staining

Specially designed built-in yellow filter, working with cobalt-blue illumination improves image contrast of cornea sodium fluorescein. Effectively increases positive rate of early corneal epithelial staining.




Corneal Topography

Sketch the contours of corneal

Lens Fitting

A simulated fluorescein image will be created based on patient’s cornea. The system will recommend several suitable lens for choose, which accelerates work flow and excludes unfit lens to save the trouble for patient to do real several fluorescein staining.


Research and develop with team SOS from EYE&ENT Hospital of Fudan University. Recommend the most precise lens based on the patient documentation.



Aberration & Simulation

Zernike wavefront aberration analysis makes plan of cataract and refractive surgeries visualized and ensures patient’s postoperative vision quality.

4 Maps

4 maps provide Sagittal Curvature,Tangential Curvature, Elevation Map, Refractive Power, and K1/K2/Km/Astig/Ecc value.
