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.

Clinical Study Evaluating Nordlys™ SWT IPL for Dry Eye Disease (DED) Due to MGD

Clinical Study Evaluating Nordlys™ System with Selective Waveband Technology (SWT)® Intense Pulsed Light (IPL) Applicators for Dry Eye Disease (DED) due to Meibomian Gland Dysfunction (MGD).

Efficacy and Safety of Thermic Devices in the Treatment of Meibomian Gland Dysfunction

Dry eye syndrome is a common eye disease that affects 1 to 2 out of 10 persons around the planet. One common cause of this disease is the meibomian gland dysfunction. Meibomian glands are very small glands located at the rim of the eyelids that produce an oily substance that prevents the evaporation of tears. When these glands are compromised, the tear film evaporates quickly and the eyes dry up. This disease presents as eye irritation, foreign body sensation, inflammation, etc. The treatment of choice for MGD is eyelid massage and warm compresses 2 times a day. However, these treatments not always work perfectly, and as a result, patients find it hard to follow doctor's orders. Another kind of treatment is thermal therapy. There are several devices that are designed to apply heat on the eyelids, such as Lipiflow, MiBo Thermoflo, and Blephasteam. In this study, we want to find out whether thermal therapy with MiBo Thermoflo works better than warm compresses and eyelid massage use in the treatment of dry eye caused by MGD. To do this, we will select several patients and will assign them randomly to either the group with thermal therapy with MiBo Thermoflo or to the group with warm compresses and eyelid massage. The Mibo group will receive 3 sessions of thermal therapy at 2 weeks interval and the control group warm compresses and eyelid massage 2 times per day. All subjects will have a follow up of 24 weeks and we will compare results for both groups at the end of the study.

Therapeutic Efficacy and Safety of Non-Invasive RF Treatment in Refractory MGD

The goal of this prospective, 24-week, double-masked, randomized, sham-controlled clinical trials to compare clinical efficacy and safety of RF and MGX with MGX alone in patients with meibomian gland dysfunction-related dry eye disease. The main question it aims to answer is whether radiofrequency treatment and meibomian gland expression is more effective in improving tear breakup time, as measured using non-invasive video keratography, compared with meibomian gland expression alone, in patients with refractory meibomian gland dysfunction-related dry eye disease. Participants will be divided into two groups, one group will receive RF treatment followed with MGX and another will receive sham treatment with MGX.

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.

Effect of an Exploratory Vehicle on Meibomian Gland Dysfunction in Patients With Demodex

The purpose of this study is to evaluate and compare the effect of two dosing regimens, BID versus TID dosing, of an Exploratory Vehicle (EV) on meibomian gland dysfunction (MGD) in patients with Demodex lid infestation.

Meibomian Gland Dysfunction Management

The purpose of this study is to compare electronic debridement of the eyelid margin (BlephEx) to manual debridement of the eyelid margin as treatment options for patients intolerant to contact lens wear consequent to Meibomian gland dysfunction.
