Meibomian Gland Expression
Applying the force your blink no longer can. Once the oil has been warmed back to liquid, controlled pressure along the lid empties glands that have been sealed for months or years.
- Duration
- About 5 minutes
- Sessions
- Often 6, every two weeks
- Comfort
- Brief pressure, well tolerated
- Downtime
- None; brief lid redness possible
What gland expression treats
Expression is for glands that are still there but are not emptying. The finding that calls for it is simple to observe: pressure on the lid produces thick, cloudy, toothpaste-like material, or nothing at all, where a healthy gland yields a clear oil.
It always follows warming, never precedes it, and it is the step that turns warming into a result.
Why a blocked gland cannot clear itself
- 01Blink pressure and thin, warm oil
- 02Lipases and saturated lipids raise the melting point
- 03The gland opening narrows and keratinises
- 04The gland keeps secreting behind the plug
- 05Back-pressure atrophies the gland
Two things move the oil
Meibum leaves a healthy gland for two reasons. The muscles in the lid squeeze the gland with every blink, and at the temperature the lid sits at the oil is thin enough to flow. In meibomian gland disease both of those change.
Bacterial lipases split the meibum into free fatty acids and the lipid mix shifts towards more saturated species, so the melting point rises and at ordinary lid temperature the secretion is a waxy paste rather than an oil. At the same time the gland opening narrows and keratinises. The result is a plug.
What happens behind the plug
What follows is the part patients are rarely told. The gland does not stop producing. It keeps secreting behind the blockage, pressure builds inside the duct, and the secretory sacs at the far end begin to atrophy under it.
On meibography, which photographs the glands through the everted lid, this shows as glands that have shortened, thinned, or gone altogether. Expression relieves the back-pressure that drives that process, which is why it is done early rather than as a last resort.
Heat first, then expression, always. Expression without warming is painful and largely ineffective against a solid plug. Warming without expression lets the oil cool and set again in the same place.
The instruments
Smart Dry Eyes is not tied to any manufacturer. The systems below are the ones most often used for this treatment in our partner centres and in European practice generally. Which one a centre runs does not change the treatment you receive.
Asadi Meibum Expressor
Afidera GmbH, Berlin
A titanium plate of 4 by 10 millimetres with a tungsten-carbide coated working surface, placed behind the lid while a swab presses from outside. The coating is there for glide: a surface that drags on the conjunctiva is what makes expression hurt.

Arita Meibomian Gland Compressor
Katena / Corza Medical, United States
Forceps with broad polished tips and angled shanks, so the working surface can lie parallel to the tarsal plate and press across a whole row of gland openings rather than pinching a point.

Mastrota paddle
Standard ophthalmic instrument
A single flat jointless paddle used behind the lid with a cotton swab as the counter-pressure. Simple, inexpensive, and the instrument used in the best controlled trial of expression published to date.

What an expression session is like
Before
Anaesthetic drops, then lid cleaning, then ten minutes of warming. The warming is not preparation for your comfort; it is what makes the oil movable.
During
A second dose of anaesthetic, then the plate or paddle is placed behind the lid and a swab presses from outside, working along the lid in short sections. Pressure rather than pain: in the published trial the median score was 2 out of 10. About five minutes.
After
The lids are cleaned and an antibiotic drop is often given. Lids can look pink and feel tender for a few hours. You can leave immediately.
The course
A typical published protocol is six sessions every two weeks over twelve weeks. Your centre will set the interval from what actually comes out of the glands at each visit.
What the evidence shows for gland expression
Randomised trial, 2026, 62 patients
A randomised trial published in 2026 compared expression plus lid hygiene against lid hygiene alone in 62 patients, with the assessor masked. Expression was better on symptom scores at every time point, better on the quality of the meibum at twelve weeks, and better on tear break-up time by a little over a second at twelve weeks. An inflammatory marker in the tears fell by 47 per cent in the expression group only. No adverse events occurred.
Where lid hygiene caught up
The result that deserves attention is the one that qualifies it. Gland dropout fell faster in the expression group at four weeks, but by weeks eight and twelve the two groups were statistically indistinguishable on gland structure. Diligent lid hygiene, done properly, caught up. Expression accelerates recovery and does more for how you feel; it is not the only thing that moves the structure.
What this means for you
It also produced the single most useful finding for patients on this whole site: both groups showed real gland regeneration. Glands that look shortened or missing on meibography are not necessarily gone for good. That is worth knowing before anyone tells you your glands are beyond help.
Who gland expression suits, and who it does not
Usually a good fit
- Thick, cloudy or absent secretion when the lid is pressed
- Meibomian gland dysfunction confirmed on meibography
- After warming, as the second half of the same appointment
- Patients whose symptoms return between other treatments
Not suitable, or postponed
- Active lid or eye infection, herpes of the lid, or an acute stye
- A chalazion that needs incision
- Recent lid or intraocular surgery
- Bleeding disorders or anticoagulant treatment with fragile lid margins
- End-stage gland loss, where there is nothing left to express
What it costs
Europe
Manual expression of the meibomian glands
from €100
Follow-up visit
from €150
Entry prices. What you pay depends on the centre, on how many sessions your diagnosis calls for, and on whether treatments are combined. In Germany these are private-pay treatments: statutory insurers do not reimburse them, private insurers and Beihilfe often do, in part. Your centre confirms the figure before anything begins.
Gland expression questions
Does it hurt?
It is pressure rather than pain, and it is brief. In the trial that measured it, patients scored the discomfort at 2 out of 10 on average. Anaesthetic drops are used, and expression that is genuinely painful usually means the warming step was inadequate.
Can I do this myself?
No, and pressing hard on your own eyelids can damage the lid margin without emptying anything. The force needed is applied against a plate held behind the lid, which is not something you can do to yourself, and the practitioner is watching what comes out to judge how hard to press.
Is it the same as LipiFlow or iLux?
Those devices combine heating and compression in one step, automatically. Manual expression separates the two and lets the practitioner see and grade what each section of lid produces. The published comparisons do not show the automated systems to be superior, and they cost considerably more per treatment.
My glands look shortened on meibography. Is it too late?
Not necessarily. In the randomised trial above, both groups showed measurable gland regeneration over twelve weeks. Complete dropout at the end stage is a different matter, and that is what the imaging is for.
