Dacryocystorhinostomy (DCR)
What Is Dacryocystorhinostomy?
If you have been living with constant tearing, sticky discharge, or painful infections near the corner of your eye, we understand how frustrating these symptoms can be. Dacryocystorhinostomy, commonly called DCR, is a surgical procedure that creates a new drainage pathway for tears when the nasolacrimal duct (the channel that normally carries tears from the eye into the nose) becomes blocked. A blocked tear duct can interfere with reading, driving, and everyday comfort, and DCR is designed to restore the natural flow of tears from the eye into the nasal cavity.
Tears are produced by the lacrimal gland above each eye and spread across the surface with every blink. They then drain through two tiny openings called puncta, located on the inner corners of the upper and lower eyelids, into small channels called canaliculi. From there, tears collect in the lacrimal sac and flow down through the nasolacrimal duct into the nose. When any part of this pathway becomes narrowed or blocked, tears have nowhere to go and begin pooling on the eye surface, leading to chronic watery eyes and potential infection.
Nasolacrimal duct obstruction (NLDO) can develop gradually due to chronic inflammation, age-related narrowing of the duct, or scar tissue from previous infections. Conditions such as chronic sinusitis, nasal polyps, or prior facial trauma can also contribute to duct closure. In some cases, the blockage occurs without an identifiable cause, which is known as primary acquired nasolacrimal duct obstruction, the most common reason adults undergo DCR. Acquired NLDO affects an estimated 3 to 5 percent of adults and is significantly more common in women, with a female-to-male ratio of approximately 3 to 1 (Cleveland Clinic, 2026).
How DCR Surgery Works
External DCR is the traditional approach and involves a small incision, typically about one centimeter long, on the side of the nose near the inner corner of the eye. Through this opening, our oculoplastic surgeon carefully removes a small window of bone between the lacrimal sac and the nasal cavity, then creates a direct passageway for tear drainage. A thin silicone stent is usually placed through the new opening to keep it patent while healing occurs. The incision is closed with fine sutures that leave a barely visible scar once fully healed. Published research reports success rates of 85 to 95 percent for external DCR (PMC, 2024).
Endoscopic DCR achieves the same goal but approaches the lacrimal sac from inside the nose using a small camera and specialized instruments. Because there is no external incision, this technique leaves no visible scar and may be associated with faster initial symptom relief, with many patients noticing improvement within one to two weeks compared to three to four weeks with the external approach. Success rates for endoscopic DCR range from 80 to 90 percent, and patient satisfaction tends to be higher due to the shorter recovery period and absence of a skin incision.
Regardless of the approach chosen, our oculoplastic surgeon typically places a soft silicone tube through the newly created opening during surgery. This stent helps maintain the drainage pathway as the tissue heals and prevents premature closure. The tube remains in place for approximately six to twelve weeks and is then removed during a brief office visit.
DCR is typically performed under general anesthesia, though some endoscopic cases can be completed with local anesthesia and sedation. The procedure generally takes between 45 and 90 minutes, and most patients return home the same day. Our oculoplastic surgeon will discuss which anesthesia approach is most appropriate based on your medical history and comfort level.
Who Is a Good Candidate for DCR?
We typically recommend DCR after less invasive options, such as warm compresses, antibiotics for infection, or duct probing and irrigation, have not resolved the obstruction. The most frequent reasons patients undergo DCR include the following:
- Persistent epiphora (excessive tearing) that interferes with daily activities, reading, or driving
- Recurrent dacryocystitis (infection of the lacrimal sac) with swelling, redness, and tenderness near the inner corner of the eye
- Chronic mucoid or mucopurulent discharge from the tear duct
- Failed previous treatments such as duct probing, balloon dilation, or stenting
Before recommending DCR, we perform a thorough evaluation that includes irrigating the tear drainage system to confirm the location and severity of the blockage. Additional imaging, such as a dacryocystogram or CT scan, may be ordered if the anatomy is complex or if prior surgery has been performed. We also review your overall health, current medications, and any history of nasal or sinus conditions that could affect the surgical approach.
DCR is effective across a wide age range, though it is most commonly performed in middle-aged and older adults where acquired duct obstruction is most prevalent. For infants and young children with congenital nasolacrimal duct obstruction, less invasive procedures such as probing or balloon catheter dilation are typically attempted first, with probing success rates of 85 to 95 percent when performed around 12 months of age. Patients with active sinus infections or uncontrolled bleeding disorders may need to address those issues before proceeding with surgery.
Benefits and Recovery
The primary benefit of DCR is the restoration of normal tear drainage. Most patients experience a significant reduction or complete elimination of excessive tearing and discharge after surgery. This improvement can make a meaningful difference in activities such as reading, working at a computer, and driving, all of which become difficult when tears constantly blur your vision. Beyond the physical symptoms, many patients describe an improved quality of life, as the constant need to dab or wipe the eyes is resolved and the redness and skin irritation that often accompany chronic tearing improve.
Patients who suffer from repeated bouts of dacryocystitis gain particular benefit from DCR, as the new drainage pathway eliminates the stagnant tear pool where bacteria tend to accumulate. Once the obstruction is bypassed, the cycle of infection, antibiotics, and reinfection is broken. This not only reduces discomfort but also lowers the risk of more serious complications such as orbital cellulitis.
Most patients can return to light daily activities within a few days of surgery. We ask that you avoid strenuous exercise, heavy lifting, and nose blowing for approximately two weeks to allow proper healing and reduce the risk of bleeding. Antibiotic and anti-inflammatory eye drops and nasal sprays are typically prescribed for the first several weeks. The silicone stent is removed at a follow-up visit, usually six to twelve weeks after surgery, and this removal is brief and well tolerated. If you have undergone other procedures such as eyelid surgery, you will find the recovery timeline for DCR to be similar in scope.
Published research consistently reports anatomical success rates of 90 to 95 percent or higher for external DCR, and the results are typically permanent. The small bone window created during surgery does not tend to close over time, making revision surgery uncommon. In the vast majority of cases, DCR provides lasting relief, with studies following patients for five years or more showing sustained results.
Frequently Asked Questions
As with any surgical procedure, DCR carries some risks. The most common side effects include mild bruising and swelling around the surgical site, minor nosebleeds in the first 48 hours, and temporary nasal congestion as the tissues heal. Less common complications include infection, displacement of the silicone stent, or narrowing of the new drainage pathway over time. Our oculoplastic surgeon will review these risks with you in detail during your consultation so you can make an informed decision.
For mild or partial blockages, less invasive options such as balloon dacryoplasty or placement of a stent alone may be attempted first, though these methods generally have lower long-term success rates than DCR. Conjunctivodacryocystorhinostomy, which places a small glass tube called a Jones tube to bypass the entire drainage system, is reserved for patients with canalicular obstruction where standard DCR is not feasible. For most adults with complete nasolacrimal duct blockage, DCR remains the standard of care.
Because DCR is a medically necessary procedure performed to treat a functional problem rather than a cosmetic concern, it is typically covered by most medical insurance plans. The cost can vary based on the surgical approach, the facility where the procedure is performed, and your individual coverage. Our team can help verify your benefits and discuss any anticipated out-of-pocket expenses during your consultation.
Many patients begin to notice reduced tearing within the first one to two weeks, particularly with the endoscopic approach. Full results are typically apparent once the silicone stent is removed and post-surgical swelling has resolved, which is usually around six to twelve weeks after the procedure. Our oculoplastic surgeon will monitor your healing at scheduled follow-up visits to ensure the new drainage pathway is functioning well.
While bilateral nasolacrimal duct obstruction can occur, we typically perform DCR on one side at a time. This approach allows for a more comfortable recovery and enables us to monitor healing before proceeding with the second side if needed. The timing between procedures depends on how your first eye heals and your overall comfort level.
Preparing thoughtful questions can help you feel confident about your decision. You may want to ask which technique, external or endoscopic, is recommended for your specific type of blockage, and what the expected timeline for improvement looks like. It is also helpful to ask about any medications you should stop before surgery, whether you will need someone to drive you home, and what signs during recovery would require a call to our office.
