Dry Eye Syndrome:
Alteration of the lacrimal film
In normal conditions, our ocular surface is permanently lubricated and covered by the tear film. Generally speaking, dry eye disease is a common pathology that affects around 20 % of the population, and results from an alteration of the tear film, either caused by insufficient production or by excessive evaporation of our tears.
The tear film has 3 main components: mucous, aqueous and lipid. The main function of the lipid one is to give stability to the tear film. This means that the lipid component allows the tear film to cover the surface of the eye when the eyelids are not closed. Those lipids are produced by the Meibomian glands that are located in the eyelid margin. So, any alteration of the Meibomian gland function produces a reduction of the tear lipid component, increment on the evaporation of the tear film, inflammatory reaction to the ocular surface and a wide variety of symptoms. We call this condition Meibomian Gland Dysfunction (MGD). This is the cause of Evaporative Dry Eye.
Patients with MGD can develop anatomical modifications of the eyelid margin, including atrophy of the Meibomian glands orifices, styes, chalazion and in more serious cases, apparition of micro-ulcerations of the corneal epithelium.
Symptoms:
Patients with MGD and Evaporative Dry eye typically suffer visual alterations during long periods of short-distance tasks (work on computer screens…) with a feeling of “eye burning” and eye discomfort. Typical symptoms include:
- Gritty eyes
- Pain / burning sensation
- Photophobia: feeling of discomfort in strong light (sun) or from car headlights in the dark
- Blepharospasm: eyelid blinking can become increasingly frequent without bringing any relief.
- Decreased visual activity (blurry vision): screen reading difficulties, driving at night, watching TV
- Paradoxal tear increase
- Difficulty in wearing contact lenses

Traditionally, Evaporative Dry Eye Disease secondary to MGD has been treated by palliative solutions like eyelid hygiene measures, artificial tears, topical anti-inflammatories and lacrimal plugs. However, the problem is chronic, so the patient’s quality of life can be affected while following those treatments permanently. Therefore, it is definitely better to use long lasting measures in order to minimize or eliminate requiring traditional treatments.
E-Eye is a device that generates a new type of polychromatic pulsed light by producing perfectly calibrated and homogenous sequenced light pulses. The energy, spectrum and time period are precisely set to stimulate the Meibomian gland in order for them to return to their normal function.
E-Eye IRPL treatment provides a long-lasting solution to the pathological problem. It aims to stimulate the Meibomian glands to produce and excrete lipids, so they can recover their natural function again. The eye discomfort usually disappears very quickly after the treatment and the inflammatory symptoms can be regulated after a few weeks.
2. Nervous stimulation
3. Meibomian gland stimulation
4. Lipid layer secretion
5. Lacrimal flow stabilization
6. Inflammation reduction
7. Symptomatic relief
- Session treatment only takes a few minutes.
- Patients are comfortably seated on a treatment stretcher, preferably tilted. A ceramic eyewear protection is adjusted on the patient’s eyes. Then a special optical gel is applied on the cheekbone and the temporal areas.
- A series of 5 flashes are applied under one eye, starting from the inner canthus to the temporal area.
- The same process is then repeated on the fellow eye.
- Just 3 to 4 sessions:
- Only a few minutes per session
- Short treatment protocol
- Day 0
- Day 15
- Day 45
- Day 75 (optional)
- Efficiency in 85% of cases
- Lasting effects: over 3 years for 60% of patients
- Cumulative effects:
- The long lasting results are due to more sessions done
- Patients must wear sunblock for 15 days after each session.
