Description
The MediWorks DEA520 is a multifunctional ocular diagnostic platform that integrates corneal topography and dry-eye analysis into a compact, self-contained system.
Its 50-ring Placido projection system provides detailed information about corneal shape, curvature, elevation, refractive power and optical aberrations. The system also supports pupil and corneal-diameter measurements, comparative examinations and simulated fluorescein patterns for contact and orthokeratology lens fitting.
For ocular-surface evaluation, the DEA520 incorporates white, infrared and cobalt-blue illumination. Its examination functions include non-invasive tear-film breakup time, tear-meniscus height, meibomian gland assessment, lipid-layer observation, conjunctival redness analysis, blink-quality analysis, eyelid-margin imaging and corneal fluorescein staining.
The integrated computer, 10.1-inch touchscreen, automatic right/left eye recognition and electrically controlled chin rest simplify operation and help maximize available examination-room space. DICOM compatibility, wired and wireless networking, external display connectivity and visual reports support clinical documentation and patient communication. Official MediWorks product information
