NIBUT
More than 8.8mm diameter Placido ring projection. Auto identify break up area and analyze NIBUT intelligently.
Identify and calculate percentages of conjunctival congestion and ciliary congestions and evaluate severity of eye congestion.
Automatic identification system depicts tear meniscus area and measures the tear height intelligently.
Observe lipid layer dynamic and distribution by video recording compared with standard templates. It’s helpful for judging MGD.
The high resolution image supports zoom in to meet examination requirements of overall shape of eyelid margin and its slight change.
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.
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.
Zernike wavefront aberration analysis makes plan of cataract and refractive surgeries visualized and ensures patient’s postoperative vision quality.
4 maps provide Sagittal Curvature,Tangential Curvature, Elevation Map, Refractive Power, and K1/K2/Km/Astig/Ecc value.
