Clinical Investigation Between the Topical Administration of a Tear Substitute With Ancillary Medicinal Substance and Hyaluronic Acid 0.3% (FBV_01) vs Hyaluronic Acid 0.3% in Subjects in the Treatment From Moderate to Severe DED
The goal of this clinical investigation plan is to evaluate the performance, tolerability, safety, and compliance of an ophthalmic solution containing an ancillary medicinal substance and hyaluronic acid 0.3% (FBV\_01) compared with hyaluronic acid 0.3% alone in adult men and women (≥18 years) with moderate-to-severe dry eye syndrome. The main questions it aims to answer are: * Is the ophthalmic solution containing an ancillary medicinal substance and hyaluronic acid non-inferior in improving the clinical performance outcomes of dry eye compared with hyaluronic acid alone? * Is the investigational device safe and well tolerated, with acceptable partecipant compliance over the treatment period? Researchers will compare the medical device containing an ancillary medicinal substance and hyaluronic acid 0.3% (FBV\_01) to hyaluronic acid 0.3% alone to see if the combination provides at least equivalent clinical benefit without increased safety issues. Participants will be randomly assigned (1:1) to one of two treatment groups in a multicenter, prospective, randomized, open-label, controlled study. Participants will instill 1 drop in both eyes 4 times daily (every 4 ± 1 hours) for 30 ± 4 days and attend study visits for assessments of dry eye signs and symptoms, safety, tolerability, and treatment compliance. The study plans to enroll 74 partecipants, with an enrollment period of about 11 months and a total study duration of approximately 12 months (from first partecipant first visit to last partecipant last visit).

Protecting the Eyes of Gamers With Lubricating Eyedrops
The excessive use of screens particularly amongst digital gamers can adversely impact the health of the surface of the eyes with symptoms and signs of surface damage. While strategies including limiting screen time exist, these may be ineffective given the widespread rise of digital device use and gaming culture in the modern era. There is limited evidence for the protective effect of lubricating eyedrops on the ocular surface for handheld console and computer gamers. The aim of this study is to investigate the protective effect of a lubricating eyedrop (TheaLoz Duo) on the surface of the eyes in handheld console and computer gamers. The main question it aims to answer is whether TheaLoz Duo could protect the surface of the eyes from dessication and alleviate symptoms of dry eye disease in handheld console and computer gamers. Participants will receive either the lubricating eyedrop first for 1 month, followed by a control condition (no eyedrops) for another month, or the other way round. Participants will attend 3 visits in total, each separated by 1 month apart. During each visit, routine clinical assessments of the front of the eye will be conducted. Subsequent findings from this timely study will help improve care of the surface of the eyes for a growing population of gamers worldwide.

Photobiomodulation With REd vs BluE Light (REBEL)
The use of photobiomodulation or low-level light therapy (LLLT) in the ophthalmic field stemmed from dermatology which has shown impact on skin blood flow and regeneration. There has been a rise in clinical interest with emerging evidence in the benefits of photobiomodulation in managing chronic inflammatory conditions such as dry eye disease including improvements in ocular discomfort symptoms, tear film stability and tear volume. Despite the observed clinical benefits, limited research has been done to compare photobiomodulation utilising different wavelengths, as most research on dry eye disease has focused on red wavelengths. It has been purported that blue wavelengths may disrupt microbial growth while red wavelengths stimulate energy production and hence increase heat in the affected tissues, although research into these differential impacts at the ocular surface and external eye has been limited. Hence, the aim of this exploratory clinical trial is to compare the impact of using LLLT incorporating red versus blue wavelengths on eyelid haemodynamics and microbiome, as well as conventional ocular surface measures of patients with dry eye disease and blepharitis (inflammation of the eyelids). Participants with dry eye disease, oil gland disruption and blepharitis will receive 3 treatments with these LLLT, each separted by 1 week apart, and followed up to 1 month after the final treatment session. Participants will be randomised to either of 3 groups: Red light only group, Red + Blue light group, or a sham treatment group.

Assessment of TFT by OCT in Healthy Subjects and Subjects With DES
Dry eye syndrome (DES) is a highly prevalent ocular condition with potential severe consequences for affected patients. DES can be either caused by decreased tear production or increased tear evaporation, both leading to an instable tear film. Despite many efforts, generally accepted methodologies to diagnose, assess the severity and monitor DES are still lacking. Moreover, widely used clinical methods such as tear break up time (BUT), fluorescein staining of the cornea or Schirmer test only poorly reflect patients´ complains. One of the main problems in the diagnosis and treatment of DES is that the most critical component - the tear film itself - is difficult to characterize. The development of new ultra-high resolution optical coherence tomography systems allows now for the direct visualization of the human tear film and for the non-invasive in-vivo measurement of tear film thickness (TFT). The investigators could recently show that this system provides excellent reproducibility and is able to assess even subtle changes in TFT induced by therapeutic interventions. However, to which extent tear film thickness is associated with other standard clinical measures of DES is currently unknown. In the present study, the investigators set out to test the hypothesis that ocular TFT is a new and good surrogate parameter for the assessment of the severity of DES. Consequently, the aim of the study presented in this protocol is to investigate whether and if so, to what extent clinical signs of DES and reported symptoms are reflected in ocular TFT. For this purpose, a cross sectional study in healthy subjects and patients with DES will be performed. This should allow the investigators to more specifically characterize the role of the tear film in DES and to assess whether measurement of TFT with OCT can be a promising surrogate parameter for the diagnosis and the follow up of DES.

Salivary Conductivity Screening for Dry Eye Disease and Sjögren's Syndrome
Dry eye disease, or keratoconjunctivitis sicca, is one of the most common diseases encountered at ophthalmologic clinics. Patient with dry eye disease commonly presented foreign body sensation, red eye, blurred vision, etc. Numerous treatments for dry eye disease are proposed due to its multifactorial etiology. Sjögren syndrome, which is one of the main etiologies of dry eye disease, is an autoimmune disease characterized by dysfunction of lacrimal and salivary glands. Although dry eye status can be easily examined by ocular surface staining, the methods quantifying salivary flow rate are hard to performed clinically, such as salivary gland scintigraphy and sialometry. Furthermore, disease activity could only rely on serum markers or salivary gland ultrasound. Recently, a portable device measuring salivary conductivity is believed to assess fluid status and renal function. Interestingly, the composition of salivary electrolytes in patients with Sjögren syndrome is different from those with other causes of hyposalivation. Thus, this study aims to evaluate whether salivary conductivity in combination with ocular surface staining can be a non-invasive diagnostic test for primary Sjögren syndrome among people with dry eye disease.

iTear Single-center, Open-label, Single-arm Study
This study aims to evaluate the effectiveness and safety of a device, iTEAR100 Neurostimulator (the device), which is designed to help people with Dry Eye Disease (DED) who are not satisfied with using artificial tears. The study will last three months and take place at one location. Thirty participants will use the iTEAR100 Neurostimulator, which stimulates the outside of the nose to help with dry eye symptoms. Participants will have three main visits: one at the start (Day 0), one after 30 days (Day 30), and one at the end of the study (Day 90). For the first 30 days, they will use the device twice a day for 30 seconds on each side of the nose. After that, they will use it as needed for the next 60 days. Before starting the treatment, participants will undergo tests to measure their initial eye condition. The effectiveness of the device will be checked by comparing these baseline measurements to those taken on Day 30 and Day 90. Participants will also fill out a questionnaire about their eye symptoms on Day 14. The main measure of success is how much the participants' symptoms improve on the Ocular Surface Disease Index (OSDI) from Day 0 to Day 30. Other measures include changes in tear production, tear quality, and eye health from Day 0 to Days 30 and 90. Participants' safety will be monitored by tracking any adverse events (side effects) throughout the study.
