LacryDiag Diagnostic Device Comes to Eye Clinic London


We are excited to announce that the LacryDiag Diagnostic Device is now available at Eye Clinic London and will be included during dry eye consultations and follow ups.


Dry eye disease is a common condition that affects millions of people worldwide. Tear film lubricates the eyes and is made up of three layers; an oily (lipid) layer, a watery (aqueous) layer, and a sticky (mucin) layer. The three tear film layers are essential for good functioning eyes as they prevent our eyes from drying. Dry eye disease is where insufficient or poor-quality tears are produced. One of the key ways to improve this condition and avoid it causing further damage is from recognising the symptoms of dry eye disease early and seeking treatment from your ophthalmologist.


Dry eye disease is multifactorial and the LacryDiag is a device with software completely dedicated to dry eye disease. LacryDiag works by performing four non-contact exams to analyse the ocular surface. It accurately evaluates the three different layers of the tear film (lipid, aqueous and mucin).


The four exams use illumination from white, blue and infrared light sources to analyse each layer:


1. Interferometry: Diagnosis of The Lipid Layer
Quantitative analysis of the volume of the tear. It measures tear meniscus height in mm, taking up to five measurements and averaging for more accuracy.


2. Non-Invasive Breakup Time: Diagnosis of The Mucin Layer
Evaluates tear film stability on the cornea and automatically measures tear breakup time in seconds.


3. Tear Meniscus: Diagnosis of The Aqueous Layer
Measures and assesses the condition of the aqueous layer.


4. Meibography: Diagnosis of The Meibomian Glands
This enables your ophthalmologist to see images of the meibomian glands and quantification of the meibomian glands. It also analyses the meibomian glands using meiboscale.


All four examinations are completed within four minutes.


LacryDiag helps to diagnose the cause of dry eye disease earlier and understanding the origin of the disease enables your ophthalmologist to offer more targeted and effective treatment. It is quick, easy and pain-free with immediate results.
