Intense Pulsed Light (IPL) therapy has emerged as an effective treatment for several ocular conditions, particularly those linked to meibomian gland dysfunction, inflammation, and post-surgical dry eye. Recent studies provide strong evidence supporting its role in improving symptoms and long-term outcomes.
Studies on IPL for Dry Eye Disease and Meibomian Gland Dysfunction
Several clinical trials have investigated IPL’s ability to treat dry eye caused by meibomian gland dysfunction (MGD).
- A 2021 randomized controlled trial by Yan Shi et al. compared IPL with meibomian gland expression (MGX) to MGX alone in 123 patients. The study found that a single IPL treatment significantly improved eye symptoms, meibomian gland quality scores, and tear secretion as measured by the Schirmer test over a 30-day period.
- A 2022 study by Toyos et al. examined the effects of four IPL sessions at two-week intervals. Patients receiving IPL combined with MGX showed statistically significant improvement in tear breakup time (TBUT) and meibomian gland secretion quality compared to those who only received MGX.
- A meta-analysis published in Acta Ophthalmologica reviewed 13 studies involving 280 patients and confirmed that IPL significantly reduced dry eye symptoms compared to no treatment. The study noted that IPL had a moderate impact when used as an adjunct to standard therapy.
- A 2023 study in Scientific Reports focused on moderate to severe cases of MGD and demonstrated that IPL improved meibum quality, gland expressibility, and reduced inflammatory markers such as MMP-9. However, the study found no significant improvement in tear osmolarity, suggesting that while IPL enhances gland function and reduces inflammation.
IPL for Demodex Blepharitis
Demodex mites are tiny parasites that live in eyelash follicles and meibomian glands, often leading to red, irritated, and inflamed eyelids. They can block oil glands, making dry eye symptoms worse. Traditional treatments like lid scrubs and tea tree oil can help, but they don’t always get rid of the mites completely.
A 2024 study by Huo et al. found that IPL was highly effective in treating Demodex-related eye problems, with key results showing:
- After three IPL sessions, 83% of Demodex-infested patients were free of mites.
- IPL did not affect vision, eye pressure, or tear production, making it a safe treatment option.
IPL is an effective way to treat Demodex blepharitis and MGD by killing mites, improving oil flow, and reducing inflammation. Patients with persistent eyelid irritation that doesn’t improve with standard treatments may benefit from IPL therapy.
IPL for Ocular Rosacea
Ocular rosacea often presents with chronic redness, irritation, and inflammation of the eyelids and ocular surface. A 2024 scoping review by Shergill et al. analyzed five studies with patients who underwent IPL treatment for ocular rosacea. The review found that 91 percent of patients had improvements from to IPL therapy. The study’s conclusion was that IPL is a promising treatment modality for ocular rosacea, as demonstrated by its ability to relieve dry eye symptoms with limited adverse events.
IPL for Post-Surgical Dry Eye
A 2024 study in the Asia-Pacific Journal of Ophthalmology investigated IPL’s role in preventing and treating post-LASIK and SMILE dry eye. The study followed patients for six months after surgery, with IPL administered before and after the procedure.

“More recently I had an issue with super dry eyes and they provided me multiple solutions and care instructions to heal them quickly. What I like is that it’s not all about just solving the issue, they taught me about long term care and what to change to ensure my eyes get the hydration they need.”

IPL Therapy: A Breakthrough for Dry Eye, Eyelid Inflammation, and Post-Surgical Recovery
Recent research supports IPL as a beneficial treatment for dry eye disease, demodex blepharitis, ocular rosacea, and post-surgical recovery. The evidence suggests that IPL improves meibomian gland function, reduces inflammation, and enhances surgical outcomes, although maintenance treatments may be necessary for long-term effectiveness.
