Thermal pulsation devices (such as LipiFlow or iLux) combine controlled heat with gentle pressure to clear blocked meibomian glands. Think of it as a precise, in-office version of warm compresses and lid massage—done at a consistent therapeutic temperature.
How Thermal Pulsation Works
The inner eyelid is warmed to about 42.5°C, softening thickened oils (meibum). At the same time, the device applies carefully calibrated pressure from the outer lid to express the melted oil from the glands.
- Heat: Liquefies thickened meibum.
- Pressure: Gently expresses the oil through the gland openings.
- Consistency: Maintains an even, safe temperature throughout treatment.
Who Is It For?
Thermal pulsation is most helpful for patients with Meibomian Gland Dysfunction (MGD) and evaporative dry eye who do not respond adequately to home hygiene alone.
- Chronic dry eye with rapid tear breakup time.
- Thick or toothpaste-like meibum on gland expression.
- Persistent symptoms despite consistent warm compresses.
What to Expect During the Procedure
- Assessment: The clinician confirms MGD and evaluates gland function.
- Device placement: The applicator sits on the eyelids and conjunctival surface.
- Treatment: Heat and pressure are applied for about 12 minutes (device dependent).
- Aftercare: You can return to normal activities immediately.
Results and Benefits
Many patients notice clearer oil secretion and improved comfort within weeks. Benefits often last several months, and some patients repeat treatment annually or as needed.
- Improved meibomian gland function.
- Reduced irritation, burning, and fluctuating vision.
- Less dependence on frequent drops.
Risks and Considerations
Thermal pulsation is generally well tolerated. Mild transient redness, lid tenderness, or temporary blurred vision can occur. It is not suitable for active eyelid infection or severe eyelid inflammation until controlled.
Important: Thermal pulsation treats gland obstruction but does not cure the underlying condition. Ongoing lid hygiene remains essential for long-term control.
How It Compares to Other Treatments
- Warm compresses: Effective but less consistent and lower temperature control.
- IPL: Better for ocular rosacea and vascular inflammation; can be combined with gland expression.
- LLLT: Gentle light therapy; often used for maintenance or in combination.

FAQs
Is thermal pulsation the same as warm compresses?
It is similar in goal, but it delivers controlled heat and pressure in a consistent, clinical setting.
How long do results last?
Many patients notice improvement for months, but durability varies and some repeat treatment periodically.
Is the procedure painful?
Most patients feel pressure and warmth rather than pain. Temporary tenderness is possible.
Does it cure MGD or blepharitis?
No. It can improve gland function, but ongoing lid hygiene is still needed.
