What You Need to Know Before You Apply

What is the purpose of this trial?

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).

Will I have to stop taking my current medications?

The trial requires participants to stop using certain medications that cause dryness, like isotretinoin and antihistamines, at least 1 month before the study starts. If you're taking prescription eye drops for dry eye, you'll need to stop using them 7 days before the study. Other medications may also need to be stopped or adjusted, so it's best to discuss your specific situation with the study team.

Is the combination of light therapy and meibomian gland expression safe for humans?

Research indicates that using intense pulsed light (IPL) combined with meibomian gland expression (MGX) is generally safe for treating meibomian gland dysfunction, which is related to dry eye disease. However, as with any treatment, there may be some adverse events (unwanted effects), so it's important to discuss potential risks with a healthcare provider. ^{1 2 3 4 5}

How is the Light Therapy + MGX treatment for dry eye disease different from other treatments?

This treatment combines intense pulsed light (IPL) therapy with meibomian gland expression (MGX) to target dry eye disease caused by meibomian gland dysfunction. Unlike standard treatments, IPL uses light to reduce inflammation and improve gland function, while MGX helps clear blockages, offering a unique dual approach to managing symptoms. ^{2 3 5 6 7}

What data supports the effectiveness of the treatment Light Therapy + MGX for Dry Eye Disease?

Research shows that using intense pulsed light (IPL) therapy along with meibomian gland expression (MGX) can help improve symptoms of dry eye disease by enhancing the function of the meibomian glands, which are crucial for eye lubrication. ^{2 3 6 8 9}

Are You a Good Fit for This Trial?

Adults aged 18-75 with dry eye disease due to meibomian gland dysfunction can join this trial. They should have a certain level of dryness and gland function, be willing to follow the study schedule, consent to photos for research use, and not wear contact lenses during the study. People with recent eye surgeries or infections, skin cancer in the treatment area, uncontrolled diseases, light-sensitive conditions or treatments are excluded.

Published Research Related to This Trial

Intense pulsed light therapy (IPL) combined with meibomian gland expression (MGX) significantly improved various measures of dry eye disease in 160 patients, including visual acuity and tear quality, after four treatment sessions.

The treatment was found to be safe, with no adverse events reported, and patients with more severe dry eye symptoms experienced greater improvements, indicating its efficacy in managing meibomian gland dysfunction.

Efficacy and safety of intense pulsed light of upper and lower eyelids in Meibomian gland dysfunction: A prospective multicentric study. Benitez-Del-Castillo, JM., López-Pérez, MD., Cano-Ortiz, A., et al.[2023]

In a study of 40 subjects with moderate to severe meibomian gland dysfunction, treatment with intense pulsed light (IPL) followed by meibomian gland expression (MGX) significantly reduced the number and severity of dry eye disease symptoms and signs over 15 weeks.

Key improvements included a 93% increase in tear breakup time and significant reductions in patient-reported symptoms and clinical signs, demonstrating the efficacy of this combined treatment approach for alleviating dry eye disease.

Prospective evaluation of intense pulsed light and meibomian gland expression efficacy on relieving signs and symptoms of dry eye disease due to meibomian gland dysfunction. Dell, SJ., Gaster, RN., Barbarino, SC., et al.[2022]

In a study of 35 patients with refractory dry eye, treatment with a combination of intense pulsed light (IPL) and meibomian gland expression (MGX) significantly improved dry eye symptoms, with 89% of patients reporting symptom relief.

The therapy also enhanced meibomian gland function in 77% of patients in at least one eye, indicating its effectiveness in addressing both symptoms and underlying gland issues.

Intense pulsed light therapy (IPL) combined with meibomian gland expression (MGX) significantly improves tear break-up time (TBUT) in patients with meibomian gland dysfunction (MGD) across various follow-up periods, indicating enhanced eye lubrication.

While there were nonsignificant improvements in dry eye symptoms measured by SPEED scores and Schirmer's test values, the overall results suggest that IPL with MGX is a promising treatment option for MGD.

Intense pulsed light therapy with meibomian gland expression for dry eye disease. Sambhi, RS., Sambhi, GDS., Mather, R., et al.[2021]

In a study of 90 patients with meibomian gland dysfunction (MGD), combination therapy using intense pulsed light (IPL) and meibomian gland expression (MGX) showed significant improvement in symptoms after three or more treatment sessions, as measured by the ocular surface disease index (OSDI) scores.

The therapy also led to improvements in meibum quality and tear break-up time (BUT) after just one session, indicating that while some benefits can be seen early, more sessions are necessary for substantial symptomatic relief.

Different Number of Sessions of Intense Pulsed Light and Meibomian Gland Expression Combination Therapy for Meibomian Gland Dysfunction. Lee, SH., Kim, M., Lee, WJ., et al.[2022]

In a study of 3,689 patients with meibomian gland dysfunction, both intense pulsed light (IPL) combined with meibomian gland expression (MGX) and MGX alone were found to be safe treatments, with low rates of adverse events (AEs) at 3.24% and 1.92%, respectively.

The IPL-MGX group experienced a higher incidence of significant AEs compared to the MGX group, leading to recommendations against IPL treatment for young children and certain patients with specific eye conditions.

Adverse Events of Intense Pulsed Light Combined With Meibomian Gland Expression Versus Meibomian Gland Expression in the Treatment of Meibomian Gland Dysfunction. Qiao, C., Li, L., Wang, H., et al.[2021]

Intense pulsed light (IPL) treatment applied directly to the eyelids significantly improved meibomian gland function and tear film stability in patients with meibomian gland dysfunction (MGD), as shown by better scores in meibomian gland yielding secretion and tear break-up time after treatment.

The study, involving 44 patients, demonstrated that IPL combined with meibomian gland expression (MGX) is a safe and effective approach for treating MGD, with only mild side effects reported, such as temporary pain and partial eyelash loss.

Intense Pulsed Light Applied Directly on Eyelids Combined with Meibomian Gland Expression to Treat Meibomian Gland Dysfunction. Rong, B., Tang, Y., Tu, P., et al.[2022]

In a study of 120 subjects with dry eye disease due to meibomian gland dysfunction, treatment with intense pulsed light (IPL) combined with Meibomian gland expression (MGX) resulted in significantly greater improvements in tear break up time and symptom scores compared to warm compresses combined with MGX.

The IPL treatment led to a 2.3-second increase in tear break up time and a 38% reduction in symptom scores, indicating its effectiveness in alleviating dry eye symptoms, while the control group showed much smaller improvements.

Intense Pulsed Light (IPL) treatment significantly improved symptoms of severe Meibomian gland dysfunction (MGD)-related dry eye in 20 patients, with a notable decrease in symptom severity measured by Visual Analog Scale (VAS) and the SPEED score after three treatment sessions.

The treatment also increased the number of expressible Meibomian gland ducts, indicating improved gland function, while maintaining a good safety profile with only 15% of patients experiencing mild, transient ocular burning.
