If you thought eye drops were the only treatment option for dry eyes, think again! These days, eye doctors can employ several innovative technologies to alleviate the symptoms of dry eyes. So, if you’ve been suffering from dry, itchy, burning eyes, consider exploring photobiomodulation therapy. It’s a non-invasive, light-based treatment used to treat a number of conditions, including dry eye disease. Two of the most popular types of photobiomodulation therapy are Intense Pulsed Light (IPL) therapy and Low-Level Light Therapy (LLLT). Could they help you achieve dry eye relief? Scroll down to learn more.
How Photobiomodulation Therapy Works
Photobiomodulation therapy devices use specific wavelengths of light to stimulate beneficial cellular processes within the tissue, including promoting cellular activity, reducing inflammation, and encouraging tissue healing. Lower energy settings prevent thermal damage.
How does this therapy work when it comes to dry eye disease?
Dry eye disease is often caused by meibomian gland dysfunction (MGD), a common condition in which the meibomian glands (located in the eyelids) do not produce enough oil or produce poor-quality oil. The lack of high-quality oil can lead to dry eyes. To treat MGD, photobiomodulation devices stimulate the cells in the meibomian glands. This can improve the quality and quantity of oils secreted by the glands, which can lead to improved tear quality. It may also help unclog blocked meibomian glands.
Two of the most common types of photobiomodulation therapy are IPL and LLLT.
Intense Pulsed Light (IPL) Therapy
IPL devices emit broad-spectrum light that targets abnormal blood vessels and inflammation associated with MGD. They use a process called selective photothermolysis, in which light energy heats and damages targeted chromophores while sparing the surrounding tissues. IPL therapy is often combined with radiofrequency (RF), which heats deeper tissues to liquefy the oil in the glands and stimulate collagen production. IPL therapy can unclog meibomian glands, improve tear film and oil quality, and reduce inflammation.
IPL therapy is also commonly used in cosmetic applications because it can fade or eliminate unwanted lesions and stimulate collagen production. It’s prized for its ability to enhance skin texture, reduce fine lines, and treat conditions like rosacea, telangiectasia, and hyperpigmentation.
Low-Level Light Therapy (LLLT)
LLLT uses red, near-infrared, or blue LED light to stimulate mitochondrial activity in the cells. It targets mitochondrial chromophores, which absorb the light, triggering biological processes. This enhances blood flow, reduces inflammation, increases ATP (the primary energy currency of cells), promotes tissue repair, and alleviates pain. Unlike IPL, no heat is involved, which is why LLLT is sometimes called “cold laser therapy.” LLLT can also promote proper meibomian gland function and reduce inflammation and oxidative stress.
LLLT is used in several other fields as well. It can help heal wounds, manage pain, rejuvenate skin, stimulate hair growth, minimize wrinkles and scars, treat psoriasis and acne, and much more!

Both of these options are painless and typically require multiple brief sessions for optimal results. They’re both great alternatives to medications or surgery. Your eye doctor may recommend that you combine IPL and LLLT for maximum dry eye relief.
