What is Meibomian Gland Dysfunction (MGD)?
Meibomian gland dysfunction is the most common cause of dry eye. You have about 25 to 30 tiny oil glands in each eyelid. Their oil forms the top layer of your tear film and stops your tears evaporating. When the glands clog, the oil thickens, the layer thins and your tears dry off the eye within seconds. That is why MGD burns and stings more as the day goes on, and why plain artificial tears help for only a few minutes. The important part is this: blocked glands can be reopened, but glands that have already shrunk away do not grow back. Meibography imaging shows us which of your glands are still there, so we can treat before more are lost.
At EyeCare Center of Orange County, we specialize in the diagnosis and treatment of meibomian gland dysfunction (mgd). Our experienced optometrists use state-of-the-art technology to provide comprehensive care and help preserve your vision.
Common Symptoms of Meibomian Gland Dysfunction (MGD)
If you're experiencing any of these symptoms, schedule a comprehensive eye examination:
Dryness that gets worse through the day
Burning and stinging
Gritty or sandy feeling, like something is in the eye
Red, irritated eyes and red lid margins
Vision that blurs and then clears when you blink
Tired, heavy eyes by late afternoon

Small lumps or repeated styes on the lid
Treatment Options for Meibomian Gland Dysfunction (MGD)
We offer comprehensive treatment options tailored to your specific needs:
IPL (Intense Pulsed Light) Therapy
Calibrated pulses of light applied to the skin around the eyes. It warms and liquefies the hardened oil inside the glands, closes the abnormal small blood vessels that keep feeding inflammation, and reduces Demodex mites on the lids. A course is usually four sessions two to four weeks apart, and most patients notice the change after the second.
IPL dry eye treatmentLow-Level Light Therapy (LLLT)
A gentle red and near-infrared light mask worn over the closed lids. It heats the glands evenly from outside and is often used in the same visit as IPL, right before the glands are expressed. It is painless and safe for skin tones that IPL is not suitable for.
Red light therapy for dry eyeMeibomian Gland Expression
After the oil has been warmed and softened, controlled pressure is applied along the lid to clear each gland. This is the step that actually empties the blockage. Warming without expression usually gives only short-lived relief.
Gland expressionMeibography Gland Imaging
An infrared photograph of the inside of your eyelid that shows the glands themselves. It tells us how many are healthy, how many have shortened and how many are gone. It is the only way to know whether you are early enough for full recovery, and it gives a picture to compare against next year.
BlephEx Lid Debridement
A soft medical spinner that scrubs the biofilm, scurf and keratin plugs off the lid margin. Clearing the lid edge lets the gland openings drain and makes every other treatment work better.
Blink Training Exercises
Most screen users blink only partly, so the lower glands are never squeezed and never empty. A short daily set of slow, complete blinks retrains the muscle. It is free, it takes two minutes a day, and it is the single home habit that changes MGD most.
Miebo (perfluorohexyloctane) Drops
A prescription drop that forms a thin film over the tear surface and cuts evaporation directly. It is aimed at exactly the problem MGD causes, so it suits patients whose tear volume is fine but whose tears vanish too fast. It contains no water and no preservative.
XDEMVY (lotilaner) for Demodex
A prescription drop for Demodex mites, which live at the base of the lashes and are a common hidden driver of blocked glands and crusted lids. It is a six-week course. We check for the collarettes at the lash base before prescribing, because not every MGD patient has mites.
Omega-3 Supplements
Omega-3 fatty acids can make the oil the glands produce thinner and easier to release. It is a slow, supporting measure — expect three months before judging it — not a replacement for clearing the blockage.
Low-Dose Doxycycline
A low oral dose used for its anti-inflammatory effect on the glands rather than as an antibiotic. It is reserved for stubborn cases, often where rosacea is involved, and is prescribed for a limited course.
Warm Compresses (adjunct therapy)
Useful between visits, but honest expectations matter: a face cloth cools within about two minutes, so it rarely reaches the temperature needed to melt hardened oil deep in a gland. Treat it as maintenance after an in-office treatment, not as the treatment itself.
Full Dry Eye Treatment Program
MGD is usually one part of a wider dry eye picture that also involves tear volume, inflammation and the lid surface. The full program tests all of it and treats the causes together.

Frequently Asked Questions
What is meibomian gland dysfunction?
It is a blockage of the small oil glands in your eyelids. Their oil is the top layer of your tear film and it stops tears evaporating. When the oil thickens and the glands clog, tears dry off the eye within seconds, so the eye burns, stings and feels gritty even though it is producing plenty of tears.
How is MGD diagnosed?
With meibography — an infrared image of the inside of your eyelid that shows the glands themselves. It shows how many glands are healthy, how many have shortened and how many are already gone. We also check the oil quality by expressing a few glands and measure how fast your tear film breaks up.
Why don't warm compresses work well on their own?
A face cloth cools within about two minutes, so it never holds the temperature long enough to melt the hardened oil deep inside a gland. Home lid-hygiene routines show only modest improvement in studies. An in-office treatment holds a controlled therapeutic temperature for the whole session, treats the inflammation that re-blocks the glands, and clears the glands in the same visit.
What is IPL treatment for MGD and how effective is it?
IPL uses calibrated light pulses to warm and liquefy the hardened oil, shut down the abnormal blood vessels that feed inflammation around the lids, and reduce Demodex mites. Published work by Dell and colleagues (2017) reported significant improvement in about 87% of treated patients. Results vary with how much gland loss there already is, which is why we image the glands first.
Can meibomian glands grow back once they are gone?
No. A gland that has atrophied does not regenerate. That is the whole reason to image early and treat early. Blocked glands can be reopened and saved; lost glands cannot be replaced. Most patients stop losing further glands once the blockage and inflammation are under control.
How many IPL sessions will I need?
Usually four, spaced two to four weeks apart. Most patients feel a clear difference after the second. Afterwards, many people come back for a single maintenance session every six to twelve months — how often depends on how much gland loss you started with.
Is MGD the same as dry eye?
MGD is the most common cause of dry eye, but not the only one. Dry eye can also come from making too few tears, from inflammation on the surface, or from a lid that does not close fully. Many patients have more than one cause at once, which is why treating only one of them often disappoints.
Why do my eyes water if they are dry?
Because the eye is irritated. When the oil layer fails and the surface dries, the eye fires off a flood of watery reflex tears — but those tears have no oil in them, so they run down your cheek instead of staying on the eye. Watering eyes are one of the most common signs of MGD, not evidence against it.
Can screen work cause MGD?
It contributes strongly. Looking at a screen cuts your blink rate and, more importantly, makes most blinks incomplete, so the lower glands are never squeezed and never empty. Over years, glands that are never emptied clog and shrink. Blink training and screen breaks address the cause directly.
What is Demodex and does it matter for MGD?
Demodex are microscopic mites that live at the base of the eyelashes. They are common, and in some patients they keep the lids inflamed and the glands blocked. The sign is a tiny cuff of debris (a collarette) at the lash base. When we find them, XDEMVY (lotilaner) drops treat them over six weeks.
Will contact lenses feel better after MGD treatment?
Usually, yes. MGD is one of the main reasons people give up contact lenses in their thirties and forties. When the oil layer is restored, the lens surface stays wet longer and comfortable wearing time often goes back up.
How long does it take to feel better?
Most patients notice change after the second in-office session, which is typically four to six weeks in. Full benefit builds over the course of treatment. If you have significant gland loss on meibography, the goal shifts from cure to control — keeping what is left working.
Does insurance cover Meibomian Gland Dysfunction (MGD) treatment?
Most vision and medical insurance plans cover diagnostic exams and medically necessary treatments. We accept most major insurance plans and can help verify your coverage before treatment.
