Device for the comprehensive treatment of dry eye syndrome


It is an Intense Pulsed Light system under exclusive LIUR® technology, specifically designed for the treatment of dry eye. It is a system to facilitate the stimulation and reactivation of the Meibomian glands in the treatment of dry eyes. It is a non-invasive procedure that does not require anesthesia or interfere with daily life. Intense Pulsed Light technology is one of the innovative new technologies recognized in the TFOS-DEWS II report.

The LIUR (Ultra Regulated Intense Light) technology differs from other traditional technologies, which has been designed to reduce or eliminate those risks of application (towards the patient). This Ultraregulation of the LIUR pulses produces a stimulation effect of the natural processes of tissue regeneration, and in no case of aggression or tissue damage.

Dry eye disease of the 21st century

Dry eye syndrome is a chronic eye problem that appears when the tear film dries up more quickly than usual, the eyes do not produce enough tears to stay moist, or when tears do not do their job properly or spread properly over the eye. to the surface of the eye, largely due to the deficient secretion of the Meibonian glands that are in the thickness of the eyelids.

This multifactorial and complex condition goes beyond what is known as “not having tears”. Its consequences can range from mild but constant eye irritation to significant inflammation, and even the appearance of scars on the front surface of the eye.

The I.P.L system Thermadry® Liur® (Ultra-Regulated Intense Light), emits trains of micro-pulses of non-coherent light designed to accumulate the chosen energy density without damaging the tissue and respecting the standard cooling coefficients of the skin. The absolute filtering of UV emission and the ultra-regulation of the pulse trains allow working without the usual risks in other typical intense pulsed light systems. The LIUR system favors the stimulation and reactivation of the Meibomian glands in the treatment of eye dryness

Treating the source of dry eyes optimizes long-term results.

How do tears work?

Tears keep our eyes moist and smooth, and help focus light so we can see clearly. They also protect the eyes from infection and irritants like dirt and dust.

Every time we blink, a thin film of tears known as the “tear film” spreads across the surface of the cornea (the clear outer layer of the eye). Tears emanate from glands above the eyes, then drain into the tear ducts (small holes in the inner corners of the eyes next to the nose) and down the inside of the nose.

When your eyes don’t produce enough tears, or your tears don’t work the right way, you can develop dry eye syndrome.

Clinical manifestations of dry eye

They encompass a variety of nonspecific signs and symptoms.
The symptoms vary both in intensity and frequency.

Action mechanism

Treatments to make

The treatment with the Thermadry LIUR system, acts by restoring the normal functioning of the Meibomian glands, reducing inflammation and improving the quality of tears and, for this, four sessions are carried out at a rate of one every 15 days, the first three and the fourth. after a month. The process is repeated every 6 months approximately, although the sessions can be variable depending on the personal response.

Clinical results

Accelerates the metabolism of the meibomian gland and lacrimal gland

by stimulating the parasympathetic nervous system

Stops the vicious cycle of chronic inflammation

clotting new blood vessels and reducing inflammatory agents

Demodex decreases

through coagulation and necrosis of the pigmented exoskeleton

Why? Thermadry?

Thermadry stands out for its micro-pulse energy emission technology.

Exclusion criteria

Before carrying out a treatment, the following indications must be observed to prevent adverse skin reactions.


Do not sunbathe or perform UVA sessions before treatment to avoid increasing skin pigmentation and making it easier to produce a burn.


Treat only on intact skin, not on open wounds. This also implies not treating after chemical and/or physical peels (dermabrasion).


Do not treat, under any circumstances, on tattoos or micropigmentation of the lips or eyebrows, it can cause burns and/or change the pigmentation of the tattoo or micropigmentation.


Do not treat pregnant women.


Do not treat pigmented lesions (moles, nevus…).


Caution on epileptic people since the possible tension/fear and the use of Intense Light can trigger an attack.


Do not treat people who are undergoing treatment where photosensitizing products are used, even up to 6 months after the end of treatment (Acne treatments with Roacutan®), to avoid photosensitization reactions: antipsychotic drugs, antidepressants, steroidal anti-inflammatories, antimicrobials, antiparasitics.
