Tear Duct Surgery (DCR)

Introduction

If you have been told that your tear duct is blocked and that surgery is the next step, you are reading the right guide. Constant watering of the eyes, repeated infections near the inner corner of the eye, or a swollen tender lump beside the nose can wear on daily life in ways that are hard to explain to people who have not experienced them. Tears that should drain quietly through a small internal passage instead spill onto the cheek, blur vision, irritate the skin, and sometimes set off infections that come back again and again.

Tear duct surgery — known medically as dacryocystorhinostomy, or DCR — is the operation most commonly used when a blocked tear duct does not respond to simpler measures. It creates a new drainage pathway between the tear sac and the inside of the nose, bypassing the blocked section.

This guide explains what DCR is, why it is performed, the two main surgical approaches (external and endoscopic), how to prepare, what happens on the day of surgery, what recovery looks like over the following weeks, and what the long-term outcomes generally look like. A separate section covers tear duct problems in children, which are handled differently from adult cases.

What Is Tear Duct Surgery (DCR)?

To understand DCR, it helps to know how tears normally drain.

Your eyes produce tears continuously to keep the surface of the eye moist and protected. After tears wash across the eye, they drain through two tiny openings called puncta — one on the upper eyelid and one on the lower, near the inner corner of the eye. From there, tears travel through small channels called canaliculi into the lacrimal sac, a small reservoir nestled beside the bridge of the nose. The lacrimal sac empties into the nasolacrimal duct, which carries tears down into the nose, where they are absorbed or swallowed without you noticing.

When any part of this drainage system becomes narrowed or blocked — most often the nasolacrimal duct itself — tears have nowhere to go. They back up, overflow onto the cheek, and the stagnant fluid inside the sac can become infected.

Dacryocystorhinostomy literally means “making a new opening (stomy) between the lacrimal sac (dacryocyst) and the nose (rhino).” The surgeon creates a small opening through the thin bone that separates the lacrimal sac from the inside of the nose, so tears can drain directly into the nasal cavity, bypassing the blocked duct.

DCR is one of the most well-established operations in oculoplastic surgery (the subspecialty of ophthalmology that deals with the eyelids, tear system, and orbit). It is performed in adults and, in selected cases, in children.

Why Is Tear Duct Surgery Performed?

DCR is performed when a blocked or narrowed tear drainage system is causing symptoms that interfere with daily life, or when complications such as infection of the tear sac have developed.

The most common reasons doctors recommend DCR are:

• Persistent watering (epiphora) that does not resolve with simpler treatment and that is troublesome enough to affect reading, driving, working, or social comfort.
• Recurrent infections of the tear sac, a condition called dacryocystitis. The area beside the nose may become red, swollen, tender, and discharge pus.
• A mucocele, where the blocked tear sac becomes distended with mucus and forms a visible lump at the inner corner of the eye.
• Confirmed complete nasolacrimal duct obstruction on testing, especially if symptoms are present.
• Before certain other eye surgeries, particularly intraocular procedures, where an infected tear sac would pose a risk of spreading infection inside the eye.

A few causes of blocked tear ducts in adults are worth knowing about, because they shape how the surgery is planned:

Age-related narrowing

The most common cause in adults is gradual scarring and narrowing of the nasolacrimal duct with age, often called primary acquired nasolacrimal duct obstruction. It typically develops after the age of 40 and is more common in women, partly because of narrower bony anatomy.

Chronic sinus or nasal disease

Long-standing sinus infections, nasal polyps, allergic rhinitis, or previous nasal surgery can all contribute to blockage by narrowing the nasal end of the duct or causing surrounding inflammation.

Trauma

Fractures of the nose or the bones around the eye can damage the tear duct and scar the drainage pathway.

Inflammatory conditions

Systemic conditions such as sarcoidosis or granulomatosis with polyangiitis can involve the tear drainage system.

Tumours

Rarely, a growth within the lacrimal sac or nearby structures causes obstruction. This is one of the reasons surgeons inspect the sac during DCR and sometimes send tissue for laboratory examination.

After radiation or certain medications

Some cancer treatments, including specific chemotherapy agents and radiotherapy to the face, can scar the tear ducts.

Who Is a Candidate for DCR?

Whether DCR is the right step for any individual is a clinical decision made together with an oculoplastic surgeon after examination and testing. In general, doctors consider DCR when:

• Watering or recurrent infections significantly affect quality of life.
• Testing confirms a true anatomical blockage in the lower part of the tear drainage system (the nasolacrimal duct).
• Simpler measures have not helped or are not appropriate.
• The patient is well enough to undergo surgery and anaesthesia.

DCR may not be the first choice, or may need to be delayed or modified, in situations such as:

• An active, untreated infection of the tear sac — this is usually settled with antibiotics first, although urgent surgical drainage may be needed in severe cases.
• Blockage in the upper part of the drainage system (the canaliculi), where a standard DCR may not be enough and a different operation may be considered.
• Significant nasal pathology that needs ENT assessment first.
• Watering caused by something other than blockage — for example, eyelid laxity, ectropion (an outward-turning eyelid), or chronic eye surface disease — where treating the underlying problem may resolve the symptoms without DCR.

A careful examination is important because watering eyes have several possible causes, and not all of them are solved by creating a new drainage channel.

Alternatives to DCR

Depending on the cause and severity of the blockage, doctors may consider one or more of the following before or instead of DCR.

Conservative measures

For mild or intermittent watering, simple steps such as warm compresses, lid hygiene, treatment of eye surface dryness, or management of allergies may reduce symptoms. These do not unblock a structurally obstructed duct but can help when the watering has multiple contributors.

Antibiotics

If the tear sac is actively infected, antibiotic drops or tablets are used to settle the infection. Antibiotics treat the infection but do not open the blockage, so symptoms often return until the drainage problem itself is addressed.

Probing and irrigation

A fine probe is passed through the tear duct system, sometimes combined with flushing fluid through the duct, to check the level of blockage and occasionally to open partial obstructions. In adults with a fully scarred duct, probing alone rarely provides a lasting cure, but it is a standard diagnostic step.

Balloon dacryoplasty

A small balloon catheter is passed into the narrowed duct and inflated to stretch it open. This may be considered in selected cases of partial obstruction, often in combination with a temporary silicone tube. Long-term success is generally lower than with DCR for complete obstruction.

Silicone intubation alone

A soft silicone tube is placed through the drainage system to keep it open for several months. This may help in partial blockages or in children but is less commonly successful as a stand-alone treatment for fully blocked ducts in adults.

Treating other causes of watering

If watering is due to an eyelid problem, dry eye, or eyelash issues rather than duct blockage, the underlying cause is addressed first.

Where the duct is completely blocked and symptoms are significant, DCR offers the most reliable long-term results, which is why oculoplastic surgeons commonly recommend it in these situations.

Surgical Approaches: External and Endoscopic DCR

External DCR

In external DCR, the surgeon makes a small skin incision on the side of the nose, just below the inner corner of the eye. Through this incision, the lacrimal sac is exposed, a small window of bone is removed, and the sac is connected directly to the lining of the nose. A temporary silicone tube is often placed through the new opening to keep it open while healing.

Key features of external DCR:

• It has a long track record and is considered a benchmark for success rates.
• It gives the surgeon direct visual access to the lacrimal sac, which can be useful in complex cases, revision surgery, or when tissue samples are needed.
• It leaves a small scar on the side of the nose. In most patients, the scar fades and becomes inconspicuous, but it is technically a visible incision.
• It is usually performed under local anaesthesia with sedation, or under general anaesthesia.

Endoscopic (endonasal) DCR

In endoscopic DCR, the surgery is performed entirely through the nostril using a thin telescope (endoscope) and fine instruments. No skin incision is made on the face. The surgeon identifies the lacrimal sac from inside the nose, removes a small piece of bone, and opens the sac into the nasal cavity.

Key features of endoscopic DCR:

• No external scar, which many patients prefer for cosmetic reasons.
• Allows the surgeon to address coexisting nasal problems (such as a deviated septum or polyps) at the same time.
• Generally less bruising around the eye.
• Requires specific training and equipment; results depend significantly on surgical experience.
• Usually performed under general anaesthesia, though local anaesthesia with sedation is possible in some centres.

Variations

Some centres offer laser-assisted DCR, in which a laser is used to make the bony opening, usually through an endoscopic approach. Success rates with laser-only techniques have historically been lower than with standard external or endoscopic DCR, so it is used selectively. Revision DCR is performed when a previous DCR has failed; this can be done externally or endoscopically depending on the cause of failure and the surgeon’s preference.

Which approach is chosen depends on the cause of the blockage, the condition of the nasal anatomy, the surgeon’s experience, and patient preference. Both approaches, performed by experienced oculoplastic surgeons, produce high success rates — commonly reported in the 85 to 95 percent range in published surgical series — with broadly comparable results when matched for case complexity.

Preparing for Tear Duct Surgery

Preparation usually begins a few weeks before surgery, with a consultation that includes:

• A detailed history of your symptoms, previous eye and nasal surgeries, and general health.
• Examination of the eyes, eyelids, and tear drainage system, including syringing of the tear ducts to confirm the level of blockage.
• Nasal examination, often with a small endoscope, to check the inside of the nose.
• Imaging in selected cases, such as a CT scan, if there has been previous trauma, suspected tumour, or anatomical concerns.
• Discussion of the two surgical approaches and which is being recommended for your situation.

In the week or two before surgery, you may be asked to:

• Stop or adjust blood-thinning medications such as aspirin, clopidogrel, or warfarin — only on the advice of the doctor who prescribed them.
• Avoid herbal supplements that can increase bleeding (such as ginkgo, garlic supplements, fish oil) for around a week before surgery.
• Arrange transport home, as you will not be able to drive immediately after the procedure.
• Fast (no food or drink) for several hours before surgery if you are having general anaesthesia or sedation.
• Treat any active eye or nasal infection, which is usually done before scheduling DCR.

If you smoke, stopping — even for a few weeks before and after surgery — supports better wound healing.

What Happens During DCR Surgery

DCR is most often performed as a day-care procedure. You arrive at the hospital, have the surgery, and go home the same day in the vast majority of cases.

The general sequence is:

1. Admission and preparation. You change into a surgical gown, the team confirms your details and the side being operated on, and an intravenous line is placed.
2. Anaesthesia. Depending on the plan, this is either general anaesthesia (you are asleep), or local anaesthesia with sedation (you are relaxed and the area is numbed). The nose is prepared with decongestant spray and local anaesthetic to reduce bleeding.
3. The procedure itself. In external DCR, a small incision is made on the side of the nose, the sac is exposed, a small bony opening is created, and the sac is sewn open into the nasal lining. In endoscopic DCR, the same steps are performed through the nostril using a telescope. In both, a soft silicone tube is often passed through the tear duct openings in the eyelids, through the new pathway, and into the nose, where it is secured. The tube acts as a stent during healing.
4. Closure. In external DCR, the skin incision is closed with fine sutures. In endoscopic DCR, no external closure is needed. Light nasal packing may be placed.
5. Recovery in the day-care unit. You wake up (if you had general anaesthesia) or rest until the sedation wears off. After observation and once you are eating, drinking, and comfortable, you are discharged with instructions.

The operation typically takes 45 to 90 minutes per side. Some patients have both sides done in the same session if both ducts are blocked.

Recovery and Healing

The first few days

You can expect:

• Mild to moderate swelling and bruising around the eye and nose, particularly after external DCR.
• A blocked or runny nose, sometimes with small amounts of blood-stained discharge for several days.
• Some watering of the eye, which can paradoxically feel worse before it improves — this settles as healing progresses.
• Mild discomfort, usually controlled with simple painkillers such as paracetamol.
• A small loop of silicone tubing visible at the inner corner of the eye, if a stent has been placed.

Cold compresses applied gently to the cheek (not pressing on the eye) can reduce swelling in the first 48 hours.

The first two weeks

• Sutures on the skin (after external DCR) are typically removed at about 5 to 7 days, or they may be dissolvable.
• Bruising fades over 1 to 2 weeks.
• You will be given eye drops (often an antibiotic-steroid combination) and sometimes a nasal spray or rinse to keep the new opening clean.
• Avoid blowing your nose for at least one to two weeks — forceful blowing can disturb healing and push air into the tissues around the eye. Sneeze with your mouth open if you need to sneeze.
• Avoid heavy lifting, straining, and vigorous exercise for around two weeks.
• Swimming and contact sports are usually avoided for several weeks.

Weeks four to twelve

• The internal opening continues to mature.
• The silicone tube, if placed, is usually removed in clinic between 6 and 12 weeks after surgery. Removal is quick and generally not painful — the tube is cut at the inner corner and slipped out through the nose.
• Watering should gradually improve as healing settles.

Aftercare basics

• Use prescribed drops and any nasal preparations as directed.
• Keep the wound area clean and dry as instructed.
• Attend follow-up appointments — these are essential to check that the new pathway is opening well.
• Contact your surgeon promptly if you develop increasing pain, increasing redness or swelling, fever, heavy bleeding, or sudden visual changes.

Risks and Complications

DCR is considered a safe procedure with a long track record, and serious complications are uncommon. As with any surgery, it carries some risks, which should be discussed with your surgeon before the operation.

Possible complications include:

• Bleeding. Some nosebleed is normal in the first few days. Heavy or persistent bleeding occasionally needs medical attention.
• Infection. Wound or sinus infection is uncommon and usually responds to antibiotics.
• Scarring of the new opening. The most common reason DCR fails is that the newly created passage scars closed over weeks or months. This may require revision surgery.
• Tube-related problems. The silicone stent can become displaced, dislodged, or, rarely, cause irritation or a small slit at the inner corner of the eyelid. Tubes can usually be repositioned or removed in clinic.
• Visible scar. After external DCR, a small scar remains on the side of the nose. In most patients it is faint, but scar quality varies between individuals.
• Bruising and prolonged swelling. Usually self-limiting.
• Failure of the surgery. Persistent watering after DCR can occur in a minority of cases and may need revision surgery or further investigation.
• Damage to nearby structures. Injury to the eye itself, surrounding tissues, or, very rarely, the brain’s thin bony covering above the nose is extremely uncommon in experienced hands but is theoretically possible.
• Anaesthesia-related risks. These depend on the type of anaesthetic and your general health.

The experience of the surgeon, careful preoperative assessment, and good aftercare all reduce the chance of complications.

Life After DCR

Most people who undergo DCR for a confirmed blocked tear duct experience a meaningful improvement in their symptoms. Watering reduces, infections become less frequent or stop, and the discomfort of a swollen tear sac resolves.

A few things to keep in mind for the longer term:

• Some residual watering is possible, especially in cold or windy conditions, even after a fully successful DCR. The new pathway works well but is not identical to a natural duct.
• Routine eye care continues as normal. DCR does not change your need for glasses, cataract surgery, or other eye treatments if they arise.
• Treat sinus or nasal infections promptly, as severe nasal inflammation can occasionally affect the new opening.
• Tell future surgeons about your DCR, particularly if you ever need nasal or sinus surgery.
• If watering returns months or years later, see an oculoplastic surgeon. Sometimes the new opening narrows and can be reopened with a smaller procedure or revision DCR.

Tear duct blockage in babies and young children is a different situation from blockage in adults, and it is handled in stages.

Congenital nasolacrimal duct obstruction

Many newborns are born with a thin membrane at the lower end of the nasolacrimal duct that has not yet opened. This causes watery eyes, sticky discharge, and sometimes mild infection in the first weeks of life. It is common — affecting up to one in five infants — and, in most babies, opens on its own during the first year.

First-line management

Paediatric ophthalmologists typically recommend:

• Tear duct massage (the Crigler technique), where a parent gently presses and strokes downward over the tear sac several times a day to encourage the membrane to open.
• Cleaning the eyelids with cooled boiled water on a clean cotton pad to manage discharge.
• Antibiotic drops only if there is active infection, on medical advice.

The majority of cases resolve with these measures by 12 months of age.

Probing

If symptoms continue, paediatric specialists commonly recommend a probing procedure, typically between 9 and 18 months of age. Under brief general anaesthesia, a fine probe is passed through the duct to open the membrane. Success rates are high, particularly in younger children.

Intubation and balloon dacryoplasty

For older children, or when probing alone has not worked, the surgeon may place a silicone tube in the duct for several months or use a small balloon to widen the duct.

Paediatric DCR

DCR in children is reserved for cases where simpler measures have failed, or for specific anatomical problems. The procedure is similar to that in adults, though it requires a surgeon experienced in paediatric oculoplastic surgery and a hospital set up to care for children undergoing surgery.

For parents, the reassuring point is that the great majority of congenital tear duct blockages resolve without surgery, and even when surgery is needed it is usually a single, well-tolerated procedure.

Frequently Asked Questions

Is DCR painful?

The surgery itself is not felt, because it is performed under anaesthesia. Afterwards, most people describe mild to moderate soreness around the nose and eye for a few days, which is usually controlled with simple painkillers.

Will my watering stop completely?

In most patients, watering improves significantly, and many become completely dry. Some residual watering, particularly in cold or windy weather, can persist. The chance of complete resolution depends on the cause of the blockage, the type of surgery, and how the new opening heals.

How long does the silicone tube stay in place?

If a tube is placed, it usually stays in for 6 to 12 weeks. Some surgeons leave it longer in certain situations. Removal is a quick clinic procedure and is generally not painful.

Will I have a visible scar?

After external DCR, there is a small scar on the side of the nose. In most patients it fades to a faint line over months. Endoscopic DCR avoids any external scar because it is done through the nostril.

How soon can I go back to work?

Many people return to desk-based work within one to two weeks, depending on how they feel and the type of surgery. Jobs involving heavy lifting, dusty environments, or strenuous physical activity may need a longer break.

Can DCR be done on both eyes at the same time?

Yes, when both tear ducts are blocked, bilateral DCR is commonly performed in a single session. This is discussed during the preoperative consultation.

What if DCR does not work the first time?

If watering or infections persist or recur, the surgeon will examine the new opening, sometimes with an endoscope, to find the cause. Revision DCR — either external or endoscopic — can be performed if the new pathway has scarred down, and success rates for revision surgery in experienced hands are also encouraging.

Does DCR affect my vision?

The surgery does not operate on the eye itself and does not change your eyesight. The benefit is in comfort, appearance, and reduction in infections rather than visual sharpness.

Can the blockage come back?

The original blockage in the nasolacrimal duct is bypassed, not removed, so it does not “come back.” However, the new opening created by surgery can occasionally narrow or scar over time, which is the main reason DCR sometimes needs revision.

Is DCR safe in older adults?

DCR is performed across a wide age range, including in older adults. General fitness for anaesthesia is more important than age alone. Local anaesthesia with sedation is often preferred in older patients with other medical conditions.

Conclusion

A blocked tear duct can quietly affect daily life — the constant dabbing, the blurred vision, the embarrassment of tears running down the cheek at work or in conversation, and the worry of another painful infection beside the nose. Tear duct surgery (DCR) is the operation oculoplastic surgeons most commonly recommend when simpler measures have not worked, because it addresses the root problem by creating a new drainage pathway.

Whether performed externally or endoscopically, the goal is the same: to restore comfortable, reliable drainage of tears from the eye into the nose. Recovery is generally well tolerated, with most internal healing complete within two to three months. Success rates are high, and revision options exist if the first surgery does not give a lasting result. In children, most tear duct problems resolve without surgery, and stepped treatment from massage through probing to DCR offers solutions when needed.

Decisions about whether and when to have DCR, and which surgical approach to use, are best made together with an experienced oculoplastic surgeon after a thorough examination — one who can explain the findings in your case, discuss the alternatives, and walk you through what to expect at each step.
