S390L Firefly D130 Dry Eye Analyzer | MediWorks

Description

The MediWorks S390L Firefly + D130 combines a high-resolution digital slit lamp with specialized dry-eye analysis capabilities. Its guided workflow supports comprehensive ocular-surface examinations and generates quantitative information to assist qualified professionals with diagnosis, documentation and patient follow-up.

The system supports non-invasive tear meniscus height and tear-film breakup time assessment, meibomian gland evaluation, lipid-layer observation, eyelid-margin examination, blink analysis and conjunctival hyperemia assessment. It also facilitates fluorescein breakup-time evaluation and corneal fluorescein staining documentation.

Its fully automatic Firefly digital module simplifies image acquisition without requiring routine camera-parameter adjustments. A 12-megapixel sensor captures photographs at up to 4056 × 3040 pixels, while video can be recorded at 2592 × 1944 pixels and 30 fps.

High-quality optics, cobalt-blue illumination and a built-in yellow filter improve the visualization of fluorescein patterns, supporting anterior-segment photography and contact or orthokeratology lens fitting. The patient-management system supports record organization, image storage and DICOM integration.
