Suffering from dry eye disease can, not only, diminish our quality of life but also make daily activities such as reading, doing sports or driving, very difficult.
Furthermore, there is no age exempt from suffering from this pathology. Due to the abuse of technology by the youngest, there are already cases of dry eye disease among digital natives.

For that reason, it is currently estimated that more than 300 million people in the world suffer from this annoying pathology.

When blinking, a layer of tears is spread over the eye, keeping its surface soft, clean and smooth. The tear film is very important for good vision and is made up of three layers:

• Oil (Lipid) layer: this is the outer layer of the tear film, generated in the Meibomian glands;
• Water (Aqueous) layer: located in the middle of the three layers, is the one that cleans the eye, washing away particles to prevent infections;
• Mucin layer: produced in the conjunctiva, it helps to spread the watery layer evenly over the surface of the eye, to keep it moist. It also makes the tears stick to the surface of the eye.

Any problem with one of these components of the tear film can lead to tear instability, resulting in a dry eye sensation.

If the Meibomian glands do not produce enough fluid, it is possible that the tear film evaporates too quickly and is considered as a dry eye.

The aqueous deficiency of a dry eye occurs when the tear glands fail to produce a sufficient amount of aqueous fluid to keep the eyes properly moisturized.

The Symptoms may vary from person to person, depending on the severity of the dry eye disease:

• Burning,
• Irritation,
• Redness,
• Eye fatigue,
• Blurry vision.

It can also happen that the eyes secrete more tears than usual and we still call it dry eyes. This reaction usually occurs when the eye is not moist enough so the eye itself sends a signal to request increased tear production by flooding itself with emergency tears. However, these tears consist mostly of water and do not have the same qualities or the composition of the tear is abnormal. This is when a dry-eye-treatment should be evaluated.

Causes of dry eyes

The causes may be related both to the main Lagrimal gland – responsible for the watery part of the tear – and to the Meibomian glands, responsible for the lipid part of the tear film.

In order to effectively diagnose the real cause of this condition, we offer diagnostic tests such as:

• Shirmer test: a strip of filter paper is placed under the lower eyelid to measure the amount of tears being produced.
• Osmorality Test: analysis of a tear to determine its quality and its composition.
• Biomicroscopy
• Osmorality Test: analysis of a tear to determine its quality and its composition.
• NBUT
• Meibography

In order to diagnose the right cause of this syndrome, a variety of examinations must be carried out:

• Eyelid revision,
• Control the frequency of blinking,
• Determine the quantity and quality of tear production,
• Measure corneal sensitivity

In our center we have a medical team specialized in the diagnosis and treatment of the dry eye disease, using the latest technology. (Beyond eye drops and artificial tears.) We have the necessary diagnostic technology to detect eye dryness and thus provide an effective treatment.

Firstly, a thorough eye examination is needed to ensure a precise diagnosis to build an individualized treatment upon.

Then, we will offer the following technologies to realize the treatments:
