Meibomian Gland Dysfunction (MGD)
Meibomian gland dysfunction (MGD) — the most common cause of dry eye, treated properly in Hamilton
Meibomian gland dysfunction, or MGD, is a blockage or breakdown of the tiny oil glands that run along the edge of your eyelids. It is the single most common reason eyes feel dry, gritty, burning or tired by the end of the day — and, confusingly, one of the most common reasons eyes water. Rose Optometry in Frankton, Hamilton, runs a dedicated dry eye clinic that measures your glands before treating them, and offers every current in-clinic MGD treatment under one roof.

What the meibomian glands do
You have around 25 to 40 meibomian glands in each upper lid and 20 to 30 in each lower lid. Every time you blink, they release a thin film of oil (meibum) that spreads over the watery layer of your tears and stops it evaporating. Healthy meibum is clear and flows like olive oil. In MGD it thickens, turns cloudy or toothpaste-like, and stops coming out. The tear film then evaporates between blinks, the surface of the eye dries, and the eye becomes irritated and inflamed. Because the glands sit inside the lid, none of this is visible in the mirror — which is why so many people are told their eyes "look fine".
What MGD feels like
- Dry, gritty or sandy eyes that get worse through the day, in air conditioning, or at a screen.
- Burning or stinging, especially first thing in the morning or late at night.
- Watery eyes — reflex tearing because the surface is dry. See our page on watery eyes.
- Vision that blurs and clears with a blink.
- Red lid edges, crusting on the lashes, recurring styes or chalazia (lumps in the lid).
- Contact lenses that used to be comfortable and now are not.
- Drops that help for ten minutes and then stop helping.
That last point is the tell. Lubricating drops replace water. MGD is a shortage of oil. A drop cannot open a blocked gland, so if you are using drops several times a day and still feel dry, the drop is not the problem — the glands are.
Why it matters: gland loss is permanent
MGD is chronic and progressive. A gland that stays blocked long enough shrinks and eventually disappears, and gland tissue that is lost does not grow back. In a clinic-based study of 224 patients with dry eye disease, 86% had signs of MGD. The earlier a blocked gland is cleared and kept flowing, the more glands you keep for the rest of your life. That is the whole reason we push people to be assessed sooner rather than later.
Who gets it
Almost anyone, but it is more common with age, in people who blink less at screens, with rosacea, with eyelid mites (Demodex blepharitis), after hormonal change, with some acne and antihistamine medicines, with heavy eye makeup, and in long-term contact lens wearers. It is also common in teenagers and young adults — it is not just an older person's condition.
How we diagnose MGD at Rose Optometry
We do not guess from symptoms. At a Dry Eye Evaluation we measure:
- Meibography — an infrared photograph of the glands themselves, taken with our Medmont Meridia. It shows how many glands you have, how many are shortened or missing, and is the single most important picture in the assessment.
- TearCheck tear film analysis — non-invasive tear break-up time, tear volume and blink quality, with nothing touching the eye.
- ScoutPro tear osmolarity — a tiny tear sample measured for salt concentration, a core marker of dry eye disease that improves measurably as treatment works.
- Gland expression at the slit lamp — gentle pressure on the lid to see whether oil flows, and what it looks like when it does.
- Lid margin and lash examination — for blepharitis, Demodex collarettes and blocked gland openings.
Every one of these is repeated at review, so you and we can see whether the treatment is working rather than relying on how you feel on the day.
MGD treatments available in Hamilton
The measurements decide the treatment. Rose Optometry has each of the following on site, so you are not sent to Auckland for the one your eyes need.
In-clinic treatments
- IPL (intense pulsed light) — pulses of light over the skin around the lower lids to reduce lid inflammation and improve gland function. Usually a course of four sessions, measured before and after. One of the two best-evidenced device treatments for MGD.
- LipiFlow — vectored thermal pulsation that warms the glands from the inside of the lid and expresses them at the same time. Twelve minutes, both eyes, one treatment. The other of the two best-evidenced device treatments.
- Blephasteam — heated moisture-chamber goggles that soften hardened meibum before expression. A gentle first-line thermal treatment, also used as guided home therapy.
- Low level light therapy (LLLT) — a painless LED light mask over closed eyes that stimulates the glands from within; on its own, or in the same session as IPL.
- BlephEx — an in-clinic clean of the lid margin to remove the biofilm and Demodex debris that block gland openings. The opening step when blepharitis is part of the picture.
- Tixel 2 — thermomechanical eyelid treatment, coming to Rose Optometry; register your interest.
- Rexon-Eye — quantum molecular resonance therapy over a course of sessions, of particular interest for long-standing or mixed dry eye. The technology is here and clinics are being set up.
Home treatment that actually works
Devices open the glands. Daily habits keep them open. Depending on what we find, your plan may include a proper warm compress routine (ten minutes at a temperature that actually melts meibum — most people's flannel goes cold in ninety seconds), lid-margin cleansing, an oil-based or lipid-containing drop chosen for your tear deficiency rather than off the shelf, omega-3 supplementation where appropriate, and short courses of prescribed anti-inflammatory drops from our therapeutically qualified optometrists. Everything we recommend is available from our online store, and we will tell you plainly what is not worth buying in your case.
What to expect
A Dry Eye Evaluation takes about fifteen minutes and gives us the baseline pictures and numbers. From there we agree a plan: sometimes a single LipiFlow, sometimes a course of IPL with LLLT, sometimes six weeks of home therapy first. Most people feel a difference within a few weeks of a device treatment; the measurements usually improve before the symptoms do, and we show you both. MGD is managed, not cured, so reviews are typically at three and twelve months, with maintenance treatment when the numbers say so rather than on a fixed schedule.
We see MGD patients from Hamilton, Cambridge, Te Awamutu, Morrinsville, Huntly, Raglan and across the Waikato, and accept referrals from other optometrists and GPs. Rose Optometry is a founding member of the Dry Eye Specialist Group, a network of independent, optometrist-owned dry eye clinics across New Zealand, and works to the same protocols as our affiliated practice, Visique Rototuna Optometrists, north of the river.
Frequently asked questions
Is MGD the same as dry eye?
MGD is the most common cause of dry eye, but not the only one. Some people make too few tears (aqueous-deficient dry eye); most have evaporative dry eye from MGD; many have a mix. The measurements tell us which, and the treatment is different for each.
Can MGD be cured?
No. It is a chronic condition. But it can be brought under control so that your eyes stop being something you think about, and the glands you still have can be protected. Treatment is about keeping them.
Do warm compresses work?
Yes, if they are done properly — warm enough and long enough, every day. Most people's compress routine is too cool and too short to melt thickened meibum. We will show you a routine that works, and the in-clinic treatments do the job a compress cannot.
Which is better, IPL or LipiFlow?
They do different things. LipiFlow clears blocked glands in one session; IPL reduces the lid inflammation that blocks them, over a course. Meibography and your tear film measurements decide which you need, and some people benefit from both.
Why do my eyes water if they are dry?
Because the surface is dry and irritated, the eye fires off reflex tears — which are watery and evaporate straight away. Treating the MGD usually stops the watering. Read more on our watery eyes page.
How much does MGD treatment cost?
The Dry Eye Evaluation fee is confirmed when you book online. Device treatments are quoted at your assessment, once we know which your eyes need, and we tell you the full cost before anything is booked.

Frequently asked questions
In NZ an optometrist can calculate the prescription for glasses, fit contact lenses, diagnose and treat eye conditions and infections with medication. They can also manage ocular injuries including removing foreign objects. If surgery or specialist treatment is required they can refer to an ophthalmologist (eye surgeon), hospital, or other health care specialist. NZ-trained optometrists must complete a 5-year degree at the University of Auckland before becoming registered.
A dispensing optician has formal training in optical dispensing. They are qualified to help a client choose frames, read a prescription, discuss lens options, take measurements, order and fit glasses.
An ophthalmologist is a medical doctor who has specialised in the treatment of serious eye disease and ocular surgery such as cataract removal. They do not typically prescribe glasses or contact lenses.
While payment is generally required on the day of appointment, we do offer a number of payment options including Afterpay, Genoapay, QCard, and GoCardless.
Yes, we do.
Yes, you can.
Yes, if you are under 16 years of age you may be eligible for a subsidy for glasses. MSD criteria apply.
No. We are closed on public holidays and long weekends as we believe our staff should have the chance to enjoy this time with friends and family.
If your eyes are straightforward, almost any good optometrist can look after you well, and we would rather say that than pretend otherwise. Come to us when something is not straightforward: a prescription that will not settle, a cornea that has changed shape, a child whose short-sightedness is moving faster than it should, an eye surface that has stopped being comfortable, or a diagnosis you have been given but do not understand. Those problems are decided by measurement, and measuring them properly needs instruments most practices do not have.
Yes, and you do not need to justify it. A second opinion is not a criticism of whoever saw you first — very often they were right, and what you actually needed was the finding explained and the numbers put in front of you. What we can add is measurement. We can image the layers of your cornea and retina, map the epithelium, quantify how far your cornea sits from normal, measure the length of your eye and check your tear film objectively. That turns “something is not right” into a number, and a number either explains the problem or rules it out. Bring any previous scans, prescriptions and letters. Comparison against your own past results is often the most valuable thing in the room.
Usually. Complex is what this practice was built around — keratoconus, corneal grafts, irregular corneas after surgery or injury, severe dry eye, high prescriptions, and eyes that have been told they are not fittable with contact lenses. The Rose K lens for keratoconus was designed in this practice, and lenses of that family are now the most frequently prescribed in the world for the irregular cornea. If we cannot help, we will tell you at the first appointment and tell you who can, rather than taking you through a course of treatment that was never going to work.
Not necessarily. “Not fittable” usually means not fittable with the lens designs and the measurements available at the time. Corneal mapping, epithelial thickness imaging and modern scleral and custom lens designs have moved a long way, and eyes that were genuinely unfittable ten years ago are often routine now. What we can promise is an honest answer after we have measured, not before.
Measure things that are usually not measured. Swept-source OCT of the cornea gives us tomography, full-thickness mapping, epithelial thickness mapping and an objective ectasia risk score. Retinal OCT with autofluorescence shows cellular-level change without any dye being injected. Optical biometry measures the length of the eye to a hundredth of a millimetre, which is how myopia is properly monitored. Objective tear film assessment and osmolarity replace guessing about dry eye. Most of these produce a baseline you can be compared against for the rest of your life, and that comparison is frequently worth more than any single result.
No. Anyone can book directly. Many of our patients are referred by their own optometrist, their GP or an ophthalmologist, and just as many simply ring us. A referral letter is useful because it saves repeating history, but it is not a requirement and it is not a condition of being seen.
No, and we would not build a referral practice on that basis. We accept referrals every week from optometrists across the Waikato and well beyond — Specsavers, OPSM, Bailey Nelson, Visique, For Eyes and independent practices alike. The patient comes to us for the part that needs our instruments or our lens work, and goes back to you with a written plan and the imaging. We are also glad to talk a case through before you refer, and if you have an OCT but no biometer we can help you get objective myopia measures out of the instrument you already own. Please contact us for co-management.
Waiting is the one thing that cannot be undone. Short-sightedness is axial — the eye is physically growing too long — and that length does not come back. What treatment does is slow the rate of growth, so the earlier it starts the more length is saved. We measure axial length directly on two independent biometers and plot it against normal growth curves, which means we can see a child drifting off their expected curve before the prescription changes. There is a free 15-minute myopia chat if you want to understand the options before committing to anything. It is worth being precise about what we are all trying to achieve. Myopia control does not stop a child's eyes changing and no practice should tell a parent it will. What it does, reliably and across many published trials, is slow the rate at which the eye lengthens — and because the risk of retinal detachment, myopic maculopathy and glaucoma in later life rises with every extra millimetre, slowing that growth is how a child is kept out of the range where sight is genuinely at risk. After seventeen years of focusing on this, we are now seeing children on customised plans whose axial length is not progressing at all over a monitoring period, and in some cases measurements that come back slightly shorter than the ones before them. That is our own clinical observation in our own patients rather than a trial result, and it has to be read carefully, because the choroid thickens when treatment is working and part of an apparent reduction can be that thickening rather than the eye itself shortening. That is precisely why we measure both. We are not yet able to tell a parent that we can stop myopia in its tracks, and we will not say it until we can.
Two things: we measure it before treating it, and we hold every current treatment technology in one building. Most dry eye is treated on the basis of symptoms, which is why drops so often fail. A tear film can be failing because the oil layer is blocked, because the water layer is short, because the surface is inflamed, or because the lids are the problem, and those need different treatments. We assess the tear film objectively with TearCheck — tear film stability, the oil layer, lid and gland imaging, and an inflammation measure — and measure tear osmolarity, the saltiness of the tears, which is the closest thing to a laboratory number for dry eye. Then we treat the cause. Rose holds intense regulated pulsed light for inflammation and gland function, LipiFlow thermal pulsation to clear blocked meibomian glands from the inner lid surface, Blephasteam controlled-humidity warming, Tixel thermomechanical treatment for the lids, and Rexon-Eye quantum molecular resonance for the more severe and treatment-resistant cases. At the time of writing, and to the best of our knowledge, no other optometrist or ophthalmologist in New Zealand has all of these available under one roof. We say that as a statement of fact rather than a boast, and we would be glad for it to stop being true. Dry eye is one of the most common and most under-treated conditions we see, and there are far more people living with it than one practice can look after. Any practice wanting to build this kind of service has our encouragement and our help — please contact us for co-management, and send us the cases you are not yet set up for. Why holding all of them matters is simple. A practice with one dry eye machine will offer you that machine. Holding all of them means the assessment decides the treatment, rather than the equipment deciding it — and when the first approach does not work, the next one is in the next room rather than in another city.
Yes — from around six weeks of age. Babies and toddlers are tested with Cardiff acuity cards and retinoscopy, neither of which needs the child to read a letter, name a picture or say a word. Most of the findings that matter in a young child cause no symptoms and are invisible to a parent, which is exactly why they need looking for.
There is one good reason: a baseline. Almost everything we look for — glaucoma, macular change, a cornea beginning to alter shape, an eye that is lengthening — is diagnosed by comparison over time rather than by a single reading. A scan taken while everything is normal is the reference every future scan is measured against, and it is the one you cannot go back and take later.
Because measurement takes time and we would rather not split it across visits. A first appointment usually involves imaging as well as examination, and you should expect to have the results shown to you and explained rather than summarised. If a problem is genuinely straightforward we will say so and keep it short.
