Dry eye treatment with polychromatic pulsed light
E>Eye is a device that generates a polychromatic pulsed light by producing perfectly calibrated and homogenously sequenced light pulses.
The sculpted pulses are delivered under the shape of train pulses. The energy, spectrum and time period are precisely set to stimulate the Meibomian glands in order for them to return their normal function. The heat also generated by the flash of the IPL will warm the glands and may unblock them. The glands are also expressed manually after the treatment to help provide optimum results.
The E>Eye is the result of years of research from E-Swin, the world leader in Medical Grade IPL (Intense Pulsed Light) technology.
Primarily used in the cosmetic industry for the treatment of excessive hair growth, skin photo rejuvenation, pigmentation, vascular treatments and acne, the IPL technology is now introduced to the optometry industry for the treatment of Meibomian blepharitis (a major cause of Dry Eyes).
The E>Eye is a device that generates a polychromatic-pulsed light by producing perfectly calibrated and homogenously sequenced light pulses.
The sculpted pulses are delivered under the shape of train pulses. The energy, spectrum and time period are precisely set to stimulate and unblock the Meibomian glands in order for them to return their normal functions.
The E>Eye, – fully developed and manufactured in France under an ISO 9001 and ISO 13485 manufacturing process – benefits from an E-Swin patented technology of electronically controlled flashes.
The E>Eye is an quick and easy solution to dry eyes:
- Medically certified
- Supported by 2 clinical studies in France.
- Each session only takes 3 to 5 minutes.
- The skin is cleaned from any make-up or other cosmetics.
- Our optometrist adjusts the goggles on your eyes to protect them from the intense light generated by the device.
- A conductive clear gel is applied on the skin for the skin protection and optimum results.
- A series of 4 flashes are applied under the lower eyelid, from the external canthus to the internal canthus, using the nominal power.
- Results are immediate and cumulative.
Following an E>Eye treatment, our optometrist may choose to express the Meibomian glands for optimum results.
The stimulation leads to the Meibomian glands returning to their normal function in a very short time (a couple hours) following the treatment. This improvement will last for about a week after the initial treatment two to three weeks following the second treatment, then from a couple months onward. The effect is cumulative and may help correct even the most problematic dry eyes.
Patients are comfortably seated on a treatment chair, preferably tilted. The optometrist adjusts the metal eyewear protection on the patients head to protect their eyes from the light. They then apply a hydrogel on the skin to protect it.
A series of 4 flashes are applied under the lower eyelid, from the external canthus to the internal canthus, using the nominal power.
The same process is then repeated under the lower eyelid of the other eye.
The stimulation leads to the Meibomian glands returning to their normal function in a very short time (a couple hours) following the dry eye treatment.
This improvement will last for about a week after the initial treatment, two to three weeks following the second treatment, then from a couple of months onward. The effect is cumulative.
Patients suffering from a more severe pathology, classified on the 3rd and 4th level, will need to treat both inferior and superior eyelids. The ocular globe would need to be protected by a haptic contact lens.
Results obtained two months after the third treatment:
- Patients classified as level 1 have improved by one level.
- Patients classified as level 2 (Oxford classification) have improved by one or two levels.
- Patients classified from level 3 to 4 have improved by one to two levels.
Is it painful?
No it is not painful with the IPL technology (electronically controlled flash) E-Swin patented that has been developed for skin treatments since 2007 in France.
How many treatments do I need?
For optimum results, patients will need 3 treatments.
The first at Day 1, the second at Day 10 and the third at Day 30, the effects of the E>Eye being cumulative.
What is the delay between flashes?
About 3 to 4 seconds.
Can everybody have an E>Eye IPL treatment?
The E>Eye IPL treatment is suitable for skin phototype I (very fair skin colour) to V (dark skin colour), the only skin phototype that is not suitable is the phototype VI (black skin colour).
There are a few contra indications such as:
- not flashing birthmarks
- not flashing moles or raised skin pigmentation
- not flashing tattoos, permanent make-up or any pigmented area
- not flashing on fake tan
- not flashing directly the eyes (they must be protected by opaque safety glasses)
I have very severe dry eye issues, is it going to work for me?
Yes it is, the E>Eye has been proven to be efficient on level 0 to 4 on the Oxford classification of eye dryness. (4 being the most severe case of dry eye). Note that the E>Eye only treats the evaporative form of Meibomian gland dysfunction.
Is there any risk of cancer flashing the skin with IPL?
No there isn’t, the light of an IPL won’t cause any DNA denaturation as it is filtered between 580nm to 1200nm which is way above the dangerous limits. (UV wavelengths are filtered as well)
IPL technology has been widely used over the past 20 years in the cosmetic industry, plus the IPL flash strength used for the E>Eye isn’t half as powerful as a pigmentation treatment to give an example.
Is the E-Eye technology suitable for pregnant women?
No. The professional sector considers the technology unsuitable for pregnant women and the manufacturer, France Medical, advises the same.
Would the use of the E-Eye be user friendly whilst breastfeeding?
Yes, it is fine.
Is there any risk of hyperpigmentation after an E>Eye IPL treatment?
No risk of hyperpigmentation. In the worst case scenario you will get some redness that will disappear within 24 to 48 hours.
Where are the E>Eye IPL devices coming from?
The E>Eye devices are developed and manufactured in France by E-Swin, the world’s largest Medical Grade IPL manufacturer.
The dry-eye syndrome is a common pathology affecting – depending on the areas – between 5 to 15% of the population with symptoms increasing with age. Generally speaking, dry-eye conditions are a result of a lachrymal layer issue, either caused by insufficient tears or an excessive evaporation.
IPL: Intense Pulsed Light
Intense pulsed light, describes the use of intense pulses of non-coherent light distributed over a range of wavelengths from 500nm to 1200nm, for collagen stimulation and other purposes. A related but distinct technique is laser; the primary difference is that laser treatment uses laser-generated coherent and monochromatic light.
The two techniques are often confused. One cause of confusion is the range of names used for intense pulsed light treatments
There are 80 Meibomian cells located on the upper and lower eyelids. These cells produce a lipid called meibum which is a fat phase, their role being to avoid the tears evaporation, adapting the tears to the irregularities of the eye surface and adapting a perfectly convex dioptre.
Lipids are the major components of meibum, the oil substance that allows to avoid tear evaporation.
Lipids are made of polarised fat acids which the fluidity is insured by the body temperature and non-polarised on the surface, giving the stability of the lachrymal fluid and allowing the lubrication of the palpebral conjonctival plan. The contraction of the Riolan muscle allows the lachrymal film to spread out.
It is made of 3 layers:
The mucous layer, in contact with the ocular globe, secreted by the conjonctival mucous cells.
The aqueous layer, secreted by lachrymal glands.
The lipid layer, secreted by Meibomian glands.
Conjunctival goblet cells
The conjunctiva is a mucous membrane that covers the sclera and lines the inside of the eyelids. Throughout the conjunctiva are goblet cells that secrete mucins to protect the eye.
The E>Eye IPL is using wavelengths between 580nm to 1200nm.
Calculated in joules per cm2.
The E>Eye fluence used is between and per cm2.
The E>Eye for dry eye syndrome treatment has a Medical CE certification (European Standard). The Medical CE certification is a European standard.
The E>Eye IPL device has been registered at the Australian Therapeutic Goods Administration for the treatment of dry eye syndrome. So it is now also TGA registered in Australia.
ISO 9001 and ISO 13485 certifications
E-Swin, the French manufacturer of the E>Eye IPL device has an ISO 9001 certification for the Quality of their Management System to insure they meet the needs of their customers.
E-Swin also has an ISO 13485 certification for the design and manufacturing of medical devices.
