Meibomian Gland Expression

Meibomian gland expression is an in-office procedure used to clear clogged oil glands in the eyelids. The meibomian glands make the oil layer of the tear film; when that oil becomes thick and toothpaste-like, tears evaporate too quickly and dry eye symptoms can worsen. Expression applies controlled pressure to move obstructed oil out of the glands.

What Are Meibomian Glands?

Their Function

• Located in the upper and lower eyelids
• Produce meibum, the oil that forms the outer layer of tears
• Help keep tears from evaporating too quickly
• Roughly 30-40 glands live in each eyelid, give or take

What Happens When They're Blocked

• Oil becomes thick, cloudy, or waxy
• Gland openings clog
• Oil does not reach the tear film
• Tears evaporate too quickly
• Burning, blur, watering, and contact-lens intolerance can follow

When Is Expression Recommended?

Conditions Treated

• Meibomian gland dysfunction (MGD)
• Evaporative dry eye
• Blepharitis
• Chalazion (in some cases)

Signs You May Benefit

• Dry eye symptoms despite artificial tears
• Thick, cloudy, or no oil expressed from glands
• Gland dropout seen on imaging
• Crusting along eyelid margins

Types of Meibomian Gland Expression

Manual Expression

The doctor applies pressure along the eyelid margin to express thickened oil from the glands. It is usually done after heat. Manual expression can be uncomfortable because the glands are inflamed and plugged; the upside is that the doctor can see what comes out and where the blockage is worst.

Device-Assisted Expression

LipiFlow:

• Applies controlled heat and pressure
• Uses thermal pulsation
• Treatment takes about 12 minutes per eye
• Often more comfortable than firm manual expression

iLux:

• Handheld device
• Applies heat and compression
• Allows real-time visualization

TearCare:

• Wearable eyelid device
• Provides sustained heat
• Followed by manual expression

Other In-Office Treatments

Intense Pulsed Light (IPL):

• Reduces inflammation
• Improves gland function
• Often combined with expression

BlephEx:

• Mechanical lid debridement
• Removes debris and bacteria
• Helps with blepharitis component

What to Expect

Before the Procedure

• The lids are examined, often with gland expression at the slit lamp
• Numbing drops may be used
• Heat may be applied first
• The clinician should explain whether this is a one-time diagnostic expression, a treatment session, or part of a series

During Manual Expression

• Examiner uses fingers, cotton swabs, forceps, or a paddle-like instrument
• Pressure is applied along the lid margin
• The clinician works gland by gland or section by section
• Upper and lower lids may both be treated
• Expect pressure. Sometimes sharp pressure. It should be brief, not endless.

During Device-Assisted Treatment

• Device applied to eyelids
• Controlled heat warms glands
• Pressure expressed thickened oil
• Less hands-on than manual expression
• Duration varies by device (10-15 minutes)

After Treatment

• Mild redness or irritation possible
• Can resume normal activities immediately
• Use recommended eye drops
• Effects may take days to notice

Results

What to Expect

• Tear film may feel more stable
• Burning and fluctuating blur may improve
• Artificial tears may last longer
• Results vary depending on how many glands are still functioning

How Long Do Results Last?

• Not permanent
• Benefits may last weeks to months
• Ongoing maintenance is usually needed
• Home warm compresses and lid hygiene help stretch the benefit

Multiple Treatments

• Series of treatments often recommended
• Especially for device-assisted methods
• Frequency depends on severity

Home Care to Maintain Results

Warm Compresses

• 10 minutes daily (or as directed)
• Use heated eye mask or warm washcloth
• Followed by gentle lid massage
• Helps keep oil flowing

Lid Hygiene

• Daily lid cleaning
• Hypochlorous acid spray or foam
• Lid wipes
• Remove makeup thoroughly

Ongoing Treatment

• Artificial tears as needed
• Omega-3 supplements (may help)
• Prescription dry eye medications if indicated
• Avoid known irritants

Risks and Side Effects

Common

• Mild discomfort during procedure
• Temporary redness
• Slight eyelid swelling
• Tearing

Uncommon

• Bruising
• Irritation lasting more than a day
• Corneal abrasion (rare)

Generally Very Safe

For most patients, side effects are temporary and mild. The bigger risk is expecting too much from one treatment when the underlying MGD has been simmering for years.

Cost Considerations

Insurance Coverage

• Manual expression may be covered as part of office visit
• Device-assisted treatments often not covered
• Coverage varies by plan

Out-of-Pocket

• Device-assisted treatments typically $400-1000 per session
• Multiple sessions often recommended
• Check with your provider about costs

Frequently Asked Questions

Does meibomian gland expression hurt?

Manual expression can be uncomfortable because there is real pressure on the eyelids. Device-assisted methods are often more comfortable because heat softens the oil first. Numbing drops help the eye surface but do not make eyelid pressure disappear completely.

How often do I need this done?

It depends on the severity of your MGD. Some people benefit from treatment every few months; others need it less frequently. Home warm compresses can extend the time between treatments.

Can I do this at home?

You can do warm compresses and gentle lid massage at home-this is an important part of ongoing care. However, professional expression (especially with devices) provides more thorough gland clearance than home care alone.

Will this cure my dry eye?

MGD is chronic, so there is usually no one-time cure. Regular treatment and home care can improve symptoms and may help preserve remaining gland function.

What's the difference between LipiFlow and manual expression?

LipiFlow uses a device to provide controlled heat and pressure, treating all glands simultaneously. It's typically more comfortable and consistent but more expensive. Manual expression is lower cost but may be less comfortable and dependent on technique.

Can blocked glands be permanently damaged?

Yes, if left untreated long-term, meibomian glands can atrophy (shrink and die). This is why treating MGD early and consistently is important-you want to preserve the glands you have.
