Chalazion Surgery

What is a chalazion and what causes it?

The eyelids contain meibomian glands, which secrete lipids and help stabilise the tear film, reducing tear evaporation. Their proper function is also linked to comfort during vision and screen use; in selected cases of dysfunction, information about dry eye syndrome and IPL can complement the care plan.

When the ducts of these glands become blocked, lipids accumulate and act as a foreign body, causing a local inflammatory reaction and the formation of a reddish nodule in the eyelid. This is seen more often in patients with blepharitis; systematic treatment of blepharitis also reduces the risk of new episodes.

Over time, the inflammation subsides and a firm, painless nodule called a chalazion may remain. It usually resolves gradually, but in some cases surgical treatment is required. An initial assessment as part of a comprehensive eye examination ensures the lesion is correctly classified against other eyelid nodules.

Slit-lamp biomicroscopy helps assess the swelling, the position of the cyst and its relationship to the meibomian ducts. This maps out whether self-resolution is expected, whether conservative treatment should be extended, or whether the indications for incision and curettage are developing, without unnecessary delay.

Risk factors

Chalazion often occurs alongside blepharitis and can appear at any age. Contributing factors may include:

• Lack of sleep
• Stress
• Dehydration
• Prolonged computer use
• Air-conditioned environments
• Alcohol consumption, more rarely

The scientific evidence for some of these factors remains limited; in practice, the emphasis stays on the clinical picture, eyelid hygiene and controlling the accompanying inflammation. Differential diagnosis from other benign eyelid lesions is discussed when the course or appearance is not typical; for example, see benign eyelid lesions within eyelid conditions.

A family history or previous episodes in the same or the other eye do not always "predict" the future course, but they are a reminder of the value of prevention through a steady hygiene routine.

Treatment

Proper eyelid hygiene is the basis of treatment and is part of the guidance for blepharitis treatment.

Warm compresses and topical treatment can help early lesions resolve. Omega fatty acids may improve meibomian gland function as a complementary strategy, after medical advice.

In the conservative phase, gentle daily hygiene (without excessive rubbing), a warm compress at suitable intervals, and topical regimens only when prescribed by an ophthalmologist are usually combined; the exact dosage and duration are adjusted to the severity of inflammation and the patient's tolerance.

When a chalazion does not resolve, surgical removal (incision and curettage) is required. The length of the conservative trial and the decision for surgery are individualised according to size, discomfort and response to treatment.

Surgical removal of chalazion

The procedure is performed under local anaesthesia and is brief. Through a small incision on the inner surface of the eyelid, the contents of the cyst are removed, without creating a visible scar on the skin. The procedure leads to rapid resolution of the inflammation and, where feasible, restoration of normal gland function.

A small proportion of cases may recur; in that case, the accompanying blepharitis, hygiene and, if necessary, repeat of the procedure or further adjustment of treatment are reassessed.

After the procedure, instructions are usually given for local care (drops, avoiding rubbing), temporary avoidance of heavy make-up or swimming until permitted by the ophthalmologist, and a check-up shortly afterwards if needed. Return to work is usually quick, depending on occupation and postoperative instructions.

When is surgery needed?

About 50% of chalazia resolve with conservative treatment within 4–6 weeks. Surgical treatment is recommended when:

• There is no response to conservative treatment
• The chalazion increases in size
• A residual lump causing discomfort remains

The decision is made after a clinical examination and discussion of the alternatives; there is no single timetable for every patient. Pressing on the nodule or self-manipulation increases the risk of superinfection or worse inflammation and should be avoided without medical guidance.

Is it a chronic condition?

Not necessarily. However, in some patients, recurrences or multiple chalazia may appear over a period of time.

Controlling the accompanying blepharitis significantly reduces the likelihood of recurrence. Regular follow-up and consistent application of hygiene guidance form the most reliable long-term framework for prevention, along with early treatment of new irritation before it settles into a persistent nodule.

In frequently recurring episodes, coexisting skin conditions, hormonal fluctuations or sleep and work habits are systematically assessed, alongside the ophthalmological plan, to reduce eyelid inflammation.
