DEA 520 Pro Dry Eye + Corneal Topographer - Hans Heiss

DEA 520 Pro Dry Eye + Corneal Topographer

1 Ring 3Illuminations 9Functions

DEA 520 is a multi-purpose corneal topographer that integrated dry eye and corneal topography analysis.

Placido Ring

Thousands of measure points - ensure more data available and accurate analysis Smaller cone design - bigger projection area 3 Illuminations - white illumination, infrared illumination,cobalt blue illumination

Clinical Application

●Dry Eye Analysis
●Lens Fitting
●Cornea Morphology Diagnosis



Dry Eye Diagnosis

Make dry eye visualized

Non-Invasive Break Up Time

Interface
Comprehensive 7 dry eye examinations.

NIBUT
More than 8.8mm diameter Placido ring projection. Auto identify break up area and analyze NIBUT intelligently.

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


Lipid Layer Thickness

Observe dynamic lipid layer 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.
