Why heat from the inside
The oil in blocked meibomian glands has thickened to a waxy consistency that melts only above about 40 degrees. A warm compress applied to the outside of the eyelid rarely reaches that temperature at the glands, which sit against the inner surface, and it cools within minutes. LipiFlow places its heating element on the inside of the lid, in direct contact with the glands, and holds a controlled 42.5 degrees for the full treatment while the eye itself is insulated. Pressure applied to the outside of the lid then expresses the melted oil through the gland openings.
The treatment
After numbing drops, a sterile single-use activator is placed on each eye; its inner lid warmer sits under the eyelids and its outer cup rests on the lids. The device runs a programmed twelve minute cycle of heat and pulsed pressure. Patients describe warmth and a gentle massaging sensation. There is no downtime: most drive themselves home and resume normal activity immediately, with mild redness or lid tenderness for a day.
What to expect afterward
Glands that have been blocked resume secreting over the following weeks, so improvement is gradual: most patients notice the difference at two to four weeks and the full effect by six weeks. Published studies report improvement in gland function and symptoms in many patients, often lasting several months to a year, after which a repeat treatment can maintain it. Home care (warm compresses, lid hygiene, omega-3s and full blinks) prolongs the benefit.
Who it suits
Patients whose evaluation shows blocked but present glands on meibography, thick or absent oil on expression and a thin lipid layer. Glands that have atrophied do not recover with any treatment, which is why LipiFlow gives the best results when used before gland loss is advanced. Patients with rosacea may be offered intense pulsed light alongside, and those with significant inflammation an anti-inflammatory drop.
Cost
Thermal pulsation is usually not covered by medical insurance. If it is recommended and offered, the cost is quoted in writing at the evaluation, and FSA and HSA funds can generally be used; our team can confirm your coverage.
