Quick answer
Dry eye syndrome occurs when the tear film fails, either producing too few tears (aqueous deficiency) or tears that evaporate too quickly (evaporative dry eye). It is one of the most common and most undertreated eye conditions in the UK, causing grittiness, burning, fluctuating vision and reflex watering. A stepwise, cause-targeted treatment approach gives lasting relief.

Dry eye syndrome is one of the most common conditions seen in ophthalmology clinics — and one of the most frequently dismissed. Patients are often told to 'just use drops', when in fact there is a wide spectrum of underlying causes and a range of targeted treatments that go well beyond over-the-counter lubricants.
Key facts at a glance
- Evaporative dry eye from meibomian gland dysfunction accounts for roughly 85% of cases
- Tear film has three layers: oily, watery and mucin
- Symptoms include grittiness, burning, fluctuating vision and reflex watering
- Stepwise treatment runs from lid hygiene to in-clinic therapies
- Warm compresses twice daily soften meibomian gland secretions
- Preservative-free drops recommended for use more than four times daily
What is dry eye syndrome?
The tear film that coats the surface of the eye is a three-layer structure: an outer oily layer produced by the meibomian glands in the eyelids, a middle watery layer from the lacrimal glands, and an inner mucin layer from goblet cells in the conjunctiva. Dry eye occurs when any part of this system fails — either producing too few tears (aqueous deficiency) or tears that evaporate too quickly (evaporative dry eye).
Evaporative dry eye, caused by meibomian gland dysfunction (MGD), accounts for the majority of cases — roughly 85%. The meibomian glands become blocked, the oily layer thins, and tears evaporate faster than they should.
Symptoms
- Grittiness or a foreign body sensation — 'something in the eye'
- Burning or stinging, especially later in the day or after screen use
- Fluctuating or blurred vision that temporarily clears with blinking
- Reflex watering — the eye compensates for dryness by producing excess watery tears
- Red, irritated eyes, particularly in wind, air conditioning or smoke
- Discomfort with contact lens wear
- Difficulty with driving at night due to glare and halos
Risk factors
- Age — tear production and meibomian gland function decline naturally with age
- Female sex — hormonal changes (menopause in particular) affect tear composition
- Screen use — blinking rate drops significantly when using a computer or phone
- Contact lens wear
- Certain medications — antihistamines, antidepressants, diuretics, HRT
- Previous eye surgery — including LASIK refractive surgery or cataract surgery
- Autoimmune conditions — Sjögren's syndrome, rheumatoid arthritis, lupus
- Rosacea and blepharitis (lid margin inflammation)
Treatment: a stepwise approach
Treatment is tailored to the underlying cause and severity.
- Step 1 — Lid hygiene: warm compresses applied to the eyelids for 10 minutes twice daily soften meibomian gland secretions. Follow with gentle lid massage. This is the cornerstone of MGD treatment.
- Step 2 — Lubricating eye drops: preservative-free artificial tears used 4–6 times daily. Gel formulations for more severe symptoms. Hyaluronic acid-based drops are well tolerated.
- Step 3 — Omega-3 supplementation: evidence supports daily omega-3 fatty acids (fish oil or flaxseed) for MGD. Typically 3–6 months before benefit is noted.
- Step 4 — Topical anti-inflammatory therapy: cyclosporine A eye drops (Ikervis) or short-course steroid drops for inflammatory dry eye.
- Step 5 — Punctal plugs: tiny silicone plugs inserted into the tear drainage openings to keep tears on the eye surface longer. A quick, painless in-clinic procedure.
- Step 6 — In-clinic treatments: thermal pulsation (e.g. LipiFlow), intense pulsed light (IPL) therapy, or blephex (mechanical lid cleaning) for resistant MGD.
Who should skip expensive in-clinic dry-eye gadgets first?
Skip IPL or thermal-pulsation marketing if you have not yet done twice-daily warm compresses and lid hygiene for several weeks, or if you still use preserved drops six times a day. Those basics fail more people than lack of a device. Skip assuming cataract surgery will fix dryness — it often makes the surface worse for a while. Seek a consultant visit sooner if you have rheumatoid disease, Sjögren’s, or pain out of proportion to redness.
Can Mr Mohyudin help with dry eye in Yorkshire?
Yes for diagnosis, lid-margin disease, and for planning eyelid surgery around a dry surface. He is an oculoplastic and cataract surgeon, not a dedicated dry-eye spa. Severe inflammatory disease may need a cornea clinic. Private appointments at Spire Elland: 01422 324000. If the only issue is mild evaporative dryness, your optometrist can start step 1–2 without a surgeon.
When is watering actually dry eye, and when is it a blocked tear duct?
Reflex watering from an unstable tear film is common and is treated as dry eye. Tears running down the cheek with a wet-looking inner corner, especially if it started after lid laxity or a nasal history, may be a drainage problem — that is a syringing or DCR conversation, not another bottle of drops. Both can coexist. An oculoplastic exam looks at lids, puncta and the surface together.
How should dry eye change eyelid or cataract plans?
Optimise the surface before blepharoplasty or premium-lens cataract surgery. A dry cornea makes vision fluctuate and makes unhappy multifocal patients. Mr Mohyudin will delay or simplify a plan rather than operate through an angry surface. That is not lost theatre time; it is how you avoid paying twice.
How can you tell whether a dry-eye treatment plan is working?
Agree a review point and a small number of goals, such as better comfort at a screen, less fluctuating vision or improved contact-lens tolerance. Bring the names of the products you use and explain how often you use them. Without that information, it is difficult to distinguish a treatment that has not helped from one that has not been tried consistently. Ask which part of the plan addresses the suspected cause of your symptoms.
Changes to work habits, lid care or lubricating drops may be discussed before additional treatments. Ask for practical instructions and what to do if a product irritates your eyes. Avoid changing several products at once without advice, because it becomes harder to identify what helps. Persistent one-sided symptoms, pain, light sensitivity or reduced vision should be reassessed rather than automatically labelled dry eye. If cataract or eyelid surgery is being considered, tell that team about your symptoms and existing treatment.

Frequently Asked Questions
Can dry eye syndrome be cured?
For most patients, dry eye is a chronic condition that is managed rather than cured. However, with the right combination of lid hygiene, lubricants, dietary changes and in some cases in-clinic treatments, symptoms can be very well controlled and quality of life significantly improved.
Why do my eyes water if I have dry eye?
Paradoxically, dry eye commonly causes watery eyes. When the basal tear film is inadequate, the eye triggers reflex tearing from the lacrimal gland. These reflex tears are watery and not as effective as normal tears, so the underlying dryness persists. The key is restoring a stable baseline tear film, not suppressing the watering.
Are preservative-free drops worth paying more for?
Yes, for frequent users. If you use drops more than 4 times a day, preservative-free formulations are strongly recommended. Preservatives such as benzalkonium chloride (BAK) are toxic to the corneal surface epithelium with repeated use and can worsen dry eye over time. Unit-dose preservative-free drops cost a little more but are significantly better for the ocular surface.
Are supermarket lubricating drops good enough?
For mild evaporative dry eye, a preservative-free lubricant used often is a reasonable start. If you need drops more than four times a day, avoid preserved bottles. If you are no better after weeks of compresses and drops, you need a diagnosis, not a more expensive brand of the same bottle.
