IPL laser

If this laser is applied only below the lower eyelids and must act only a few millimeters into the skin. I understand that its action is only superficial, that it has no action on what is covered by the goggles. How does it act on the meibomian glands of the upper eyelids and on the microorganisms on the edge of the eyelashes?

Hello and thank you for submitting your ophthalmology question to our forum.

The question is absolutely logical and I asked myself this the first time. We currently know that the action of IPL (Intensive Pulsed Light) is not so much on the surface as in depth and is not limited to the contact area of ​​the handpiece and the skin. The IPL has an electromagnetic spectrum between 500 and 1200 nm, although we cut from 600 nm to avoid burns. We currently know that 630 nm and 800 nm radiations pass through the skin and reach deeper, subdermal planes, reaching in our case the Meibomian glands and it is at this level where they perform various functions, such as stimulating vascularization to improve its function. metabolism, stimulation of the meibocytes, the cells of the glands that produce the fat that will be poured into the tear, and anti-inflammatory effects that will revert to the improvement of the inflammatory process of the eyelids and the ocular surface, in addition to a neurotrophic effect that is now being investigating (activation of the nerves of the cornea, to help improve the epithelium and reduce the pain that accompanies patients with dry eye (neuropathic pain). All these effects are supported by research studies that demonstrate the beneficial effect of IPL in the eyes.

Regarding how it can act in distant areas, we know that the IPL flash penetrates deep planes and extends beyond the contact area. Experimental studies prove this, which is why it can act on the upper eyelids by applying the handpiece on the lower eyelids. In our case, we have carried out a study applying the IPL flash directly on the eyelids, with protection over the eyeball, and we have found almost no differences compared to when we do it with protective glasses. In the same way, the IPL acts on the Demodex because the flash reaches deep and distant planes and as the Demodex has a highly pigmented exoskeleton, it absorbs the pulsed light and the temperature is increased until it is destroyed (50-60ºC), but without affecting the surrounding tissues. There are also studies that demonstrate this effect, basically with a technology known as "in vivo confocal microscopy" and that allows us to see Demodex in the eyelids and how it is eradicated after IPL.

I hope this information answers your question. If you need more information, do not hesitate to continue contacting us.

Regards,
Dr Carlos Vergés
