Slit lamp with Dry Eye system SLD10L-VSM

Easy Pathogenic Diagnosis, Providing guidance for customized treatment.

Dry eye diagnostic system

Due to various causes of Dry  Eye Disease,traditional examination  is difficult  to find out the cause and quantify for the treatment.
MediWorks Dry Eye Diagnostic System can provide standardized examination and quantified causes evaluation for  Dry Eye Disease.

Dry eye classification from the 2007 DEWS Report

Non-Invasive Break Up Time

Grade 0 Normal, First Rupture Time: 10 s
Average Rupture Time: 14 s
Grade 1 Warning, First Rupture Time: 6-9 s
Average Rupture Time: 7-13 s
Grade 2 Dry eye, First Rupture Time: 5 s
Average Rupture Time: 7 s

Taking one video brings out AI analysis of NIBUT and Tear Meniscus Height
AI identify the break-up area and analyze NIBUT. Fully Automatic analysis system provides efficient quantified evaluation for the overall stability of the tear film.It automatically acquires the first break up time, average break up time, break up distribution,break up area percentage curve and time distribution.

MediWorks adopts Placido ring projection system with visible light to do the examination,the examination scope  is up to 10mm cornea diameter which brings much more comprehensive diagnosis outcome.
The non-invasive examination avoids the stimulation brought by the traditional Sodium Fluorescein Staining of the Cornea.

Non-Invasive Tear Meniscus Height

Normal: ≥0.2mm
Measures the Tear Meniscus Height and evaluates tear secretion amount and continuity, more efficient and less irritating compared with the traditional Schirmer’s test.

Insufficient tear secretion

Abnormal dynamics and conjunctival chalasis

Evaluation of Meibomian Glands Function

Grade 0: No Meibomian Glands Loss
Grade 1: Meibomian Glands Loss < 1/3 Grade 2: Meibomian Glands Loss 1/3-2/3 Grade 3: Meibomian Glands Loss >2/3

Automatic classification system provides precise and quantified diagnosis of DES caused by meibomian glands dysfunction.
With built-in infrared lighting system,doctors can observe larger image scope of the Meibomian Glands.
Adjustable depth of field makes the glands more prominent and distinguishable against the background.

Lipid Layer Thickness


Grade 1: <30
Grade 2: 30-60
Grade 3: 60-80
Grade 4: >80

White ring projection system ensures a larger examination area compared to Placido ring.By comparing with the standard grading template and recording the Lipid Layer thickness, it is helpful for judging MGD.

Eyelid Margin 

1. Normal including (Ophthalmic embolism bright, transparent)
2. Mild including (gland cap crown - glandular prominent)
3. Moderate including (glandular fat plug - disappearance of the marginal mucosa, hyperkeratosis)
4. Severe including (uneven margins, disappearance of the meibomian glands - posterior margin Blunt round, thickening, new blood)

MediWorks professional design of optical  system is capable of providing HD digital image that remains clear and sharp even zoom in,  meets the examination  requirements of the overall shape of eyelid margin and its slight change.

AI Analysis of Conjunctival Hyperemia

Normal: ≤2     Abnormal: >2

The unique AI identification system can identify and calculate percentages of conjunctival congestion and ciliary congestions and evaluate severity of eye congestion.

Cornea Sodium Fluorescein Staining

Effectively increases positive rate of early corneal epithelial staining.
Built-in yellow filter along with cobalt-blue filter makes the corneal  sodium fluorescein images more clearly.

Smart Patient Management system

Comparison of Patient records
Supports repeated comparison among medical records to evaluate treatment and guide customized treatment plan.

Patient Management system  allows doctors to build and edit medical records. Quickly search the patient case by key words.Doctors can note  patients’ situation via the software. This DICOM-supported system enables Mediview to connect with medical systems in hospitals.
