Book Your Consultation Now

External dacryocystorhinostomy (DCR) is a trusted and highly effective form of tear duct surgery, specifically designed to treat a blocked tear duct. At Blue Fin Vision® Eye Clinic, with locations in London, Chelmsford, and Hatfield, our experienced team combines medical expertise with compassionate care to restore healthy tear drainage and relieve the discomfort of persistent watery eyes.

Understanding Tear Drainage and Blocked Tear Ducts

Tears are essential for eye health, keeping the surface of the eye clean, comfortable, and protected. Normally, tears drain from the eye through tiny openings in the eyelids (puncta), passing into the tear ducts and then into the nose. When this drainage system becomes blocked, tears cannot flow away properly, leading to symptoms such as:

  • Constant watery eyes (epiphora)
  • Recurrent eye infections
  • Sticky discharge at the inner corner of the eye
  • Swelling or tenderness near the nose

A blocked tear duct can occur for several reasons, including age-related narrowing, chronic sinus or nasal conditions, previous facial trauma, or inflammation.

What is External Dacryocystorhinostomy (DCR)?

External dacryocystorhinostomy is a surgical procedure that creates a new channel for tears to drain from the eye into the nose, bypassing the blocked section of the tear duct. This is achieved through a small incision on the side of the nose, just next to the corner of the eye. The procedure is performed under local or general anaesthesia, depending on individual needs.

How the Procedure Works

  • A small, carefully placed incision is made on the side of the nose.
  • The surgeon accesses the lacrimal sac (the reservoir for tears) and creates a direct connection to the nasal cavity.
  • A new passage is formed, allowing tears to drain freely into the nose.
  • In many cases, a soft silicone stent is temporarily placed to keep the new passage open during healing.
  • The incision is closed with fine sutures, designed to heal with minimal visible scarring.

When is External Dacryocystorhinostomy Needed?

External DCR is recommended when a blocked tear duct does not respond to conservative treatments such as massage, antibiotics, or less invasive procedures. It is particularly suitable for:

  • Adults with persistent tear duct blockages
  • Patients with chronic or recurrent infections of the tear sac (dacryocystitis)
  • Individuals with complex or long-standing obstructions
  • Cases where previous tear duct surgery has not been successful

This approach is often considered the gold standard for treating tear duct obstruction, especially in adults, due to its high success rate and long-term effectiveness.

Outstanding Success Rate

External DCR is the traditional approach and is renowned for its excellent success rate of approximately 90%. This makes it one of the most reliable solutions for restoring proper tear drainage and resolving the symptoms of a blocked tear duct.

Benefits of External DCR

Choosing external dacryocystorhinostomy offers several important benefits:

  • Reliable restoration of tear drainage: Most patients experience lasting relief from watery eyes and recurrent infections.
  • Direct access for the surgeon: The external approach allows precise visualisation and correction of the blocked tear duct.
  • Suitable for complex cases: Particularly effective when the blockage is severe or previous procedures have failed.
  • Minimal visible scarring: The incision is discreetly placed and typically heals well, often becoming barely noticeable over time.

What to Expect: The Patient Journey

Before Surgery

At Blue Fin Vision®, your journey begins with a thorough consultation at one of our clinics in London, Chelmsford, or Hatfield. Your ophthalmic surgeon will:

  • Assess your symptoms and medical history
  • Perform detailed examinations and imaging to confirm the site of the blockage
  • Discuss the most appropriate treatment options for your individual needs

During Surgery

  • The procedure usually takes around 60–90 minutes.
  • You will be given anaesthesia to ensure comfort throughout.
  • The surgical team uses advanced techniques to minimise tissue trauma and promote rapid healing.

After Surgery

  • Most patients return home the same day.
  • You may experience mild swelling or bruising, which typically resolves within a week or two.
  • Antibiotic drops and nasal sprays may be prescribed to prevent infection and promote healing.
  • If a silicone stent is used, it is usually removed after 6–12 weeks in a simple outpatient visit.
  • Follow-up appointments ensure your recovery is progressing smoothly.
