Dry Eye Questionnaire

Ocular Surface Disease Index (OSDI)/McMonnies/SPEED/DEQ 5

Dry Eye Questionnaire

The built-in dry eye questionnaire is designed according to the risk factors and clinical characteristics of dry eye, providing a simple preliminary assessment for dry eye, improving diagnosis and treatment efficiency and facilitating patient follow-up.

Non-Invasive Tear Meniscus Height

AI identification system depicts Tear Meniscus area and measures the tear height automatically. Evaluate tear secretion amount and continuity objectively. More efficient and less irritation compared with the traditional Schirmer's test.

Non-Invasive Breakup Time

After taking one video, it brings out automatis result of NIBUT and Tear Meniscus Height. AI identifies the breakup area and analyzes NIBUT automatically. Fully automatic analysis system provides efficient quantified evaluation for the overall stability of tear film. It automatically acquires the first breakup time, average breakup time, breakup distribution, break up area percentage curve and time distribution.

Fluorescein Breakup Time

Meibomian Glands Function Evaluation

Get original/enhanced/result images by one click AI identification system automatically anlalyzes meibomian glands loss caused by meibomian glands dysfunction with precise and quantified diagnosis results. Built-in infrared lighting system helps doctors obtain larger image scope of the meibomian glands. Adjustable depth of field makes the glands more prominent and distinguishable against the background.

Lipid Layer Thickness

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

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.

Analysis of Conjunctival Hyperemia

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.

Blink Quality

Automatically analyze blink times, average blink interval, complete blink times and incomplete blink rate.

Corneal Fluorescein Staining

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

Clinical Papers & Literature

The Influence of Lid-Parallel Conjunctivaal Folds and Conjunctivochalasis on Dry Eye Symptoms with and Without Contact Lens Wear: A Review of the Literature

Lid-parallel conjunctival folds (LIPCOF) and conjunctivochalasis (CCH) are similar conditions that seem to be related to dry eye severity. In addition, there is a lack of studies on the topic of LIPCOF and CCH on dry eye symptoms in non-contact lens and contact lens (CL) wearers. Therefore, the aim of this study is to review the relationship of LIPCOF and CCH with dry eye symptoms in non-CL and CL wearers, as well as to report the treatment of dry eye disease (DED) in non-CL and CL wearers who present LIPCOF or CCH.

The study aims to assess the tear film before and after phacoemulsification in patients with age-related cataracts.

Obstructive Meibomian gland dysfunction (MGD) affects millions of patients around the world. Its effective treatment with intraductal meibomian gland probing (MGP), was first reported in 2010. This analysis will better equip clinicians to draw informed conclusions about both subjective and objective findings reported in MGP studies and researchers to design future robust studies that provide meaningful results.

To assess the efficacy and safety of the combination of microblepharoexfoliation (MBE), intense pulse light (IPL) and meibomian gland expression (MGX) for treatment of meibomian gland dysfunction (MGD).

Corneal nerve loss was associated with ocular pain and decreased corneal sensitivity in diabetic patients with DE. Further studies into the neurological role of ocular surface diseases can elaborate diagnostics, prognosis and treatment of diabetic patients with DE.

To assess the intraobserver repeatability of automated, objective, and noninvasive measures obtained with the S390L Firefly WDR slitlamp.
