Intense Pulsed Light (IPL) therapy is a non-invasive treatment that uses high-intensity flashes of light to reduce inflammation and unblock meibomian glands. It is one of the most effective treatments for patients with Ocular Rosacea and Meibomian Gland Dysfunction (MGD).
How It Works
IPL works through multiple mechanisms to break the cycle of inflammation:
- Closing Abnormal Blood Vessels: Blepharitis and Rosacea cause telangiectasia (tiny spider veins) on the eyelids. These vessels leak inflammatory factors. IPL energy is absorbed by the hemoglobin, sealing these vessels shut.
- Heating the Glands: The light energy converts to heat, liquefying the hardened oil in the meibomian glands, making it easier to express.
- Reducing Bacteria/Mites: The intense light helps reduce the population of Demodex mites and bacteria on the skin.
The Procedure
Safety First: Protective eye shields are placed over your eyes to protect them from the bright light.
Application: A cooling gel is applied to the skin. The doctor applies the IPL handpiece to the skin around the eyes (cheekbones, temples, and sometimes the eyelids directly if a specific ocular shield is used). You will see bright flashes of light, even with eyes closed.
Sensation: Most patients describe the sensation as a rubber band snapping against the skin. It is generally well-tolerated.
Expression: Immediately after the light treatment, the doctor may perform manual gland expression to clear the now-melted oil.
Treatment Course
IPL is not a "one and done" treatment. A typical protocol involves:
- Initial Series: 4 sessions spaced 3-4 weeks apart.
- Maintenance: A "top-up" session every 6 to 12 months to maintain results.
Who Is It For?
IPL is ideal for patients with:
- Ocular Rosacea
- Chronic MGD unresponsive to warm compresses
- Evaporative Dry Eye
Important Consideration: IPL targets pigment (melanin). It may not be suitable for patients with darker skin tones (Fitzpatrick skin types V and VI) due to the risk of depigmentation, although newer machines often have specific settings for varying skin types.

FAQs
How many IPL sessions are usually needed?
Many protocols use a short series of sessions spaced a few weeks apart, with maintenance as needed. Your clinician will tailor the schedule.
Is IPL safe for blepharitis?
When performed by trained clinicians with proper eye shielding, IPL is generally safe, but it is not suitable for every patient.
Does IPL replace lid hygiene?
No. IPL can improve gland function, but ongoing lid hygiene remains essential for long-term control.
Who may need to avoid IPL?
Patients with active skin infections, photosensitivity, or certain medications may not be suitable. A clinician should screen for safety.
