Dacryocystorhinostomy (often abbreviated as DCR) is a surgical procedure designed to bypass or remove a blockage of the tear-drainage system between the eye and the nose (the nasolacrimal duct). It aims to restore normal tear drainage (so that tears don’t overflow into the eye or run down the face), reduce recurrent infections of the tear system, and improve comfort and vision.
The process involves creating a new passage between the tear sac (lacrimal sac) and the nasal cavity by removing a small piece of bone and connecting the tissue linings of the sac and the nose. A small silicone tube (stent) is often placed temporarily to keep this new channel patent while healing occurs.
There are several variations of DCR surgery depending on the approach taken:
| Approach | Description |
| External DCR | A skin incision is made (typically by the side of the nose under the eye) to access the lacrimal sac, bone is removed, and the sac is connected to the nasal cavity. A stent is often placed. |
| Endoscopic (Endonasal) DCR | The surgeon uses an endoscope through the nose (no external skin cut) to create a bypass from the lacrimal sac into the nasal cavity, often less visible scar and potentially quicker recovery. |
| Laser DCR | A less common variation where laser energy may be used to create or assist the new channel rather than (or in addition to) mechanical bone removal. (Note: less commonly referenced but included in “tear duct surgery” options.) |
| Key Differences | External DCR | Endoscopic DCR | Laser DCR |
| Skin incision | Yes (visible skin cut) | No external cut (inside nose) | May or may not require cut; laser assisted |
| Visible scar | Possible, though small and often discreet | Minimal to none | Minimal |
| Access / anatomy | Direct view of sac & bone removal via skin | Via nasal cavity & endoscope | Via nasal cavity or small access, laser used |
| Recovery time | Slightly longer due to external incision | Often faster, less bruising | Variable |
| Suitability | Classic “gold standard” | Good for patients who want minimal scarring or have nasal/anatomical issues | Specialist selection, less widely used |
| Success rate | High (85-99% reported) | Comparable high rates (~91-96%) | Variable, depending on surgeon/institution |
Choosing the best approach depends on patient anatomy, surgeon experience, presence of nasal/sinus disease, patient preference regarding scar/visibility and speed of recovery.
Adults who suffer from persistent epiphora (constant watering of the eye), recurrent tear-sac infections (dacryocystitis), or who have failed less invasive treatments (probing/dilation/irrigation) are typical candidates for blocked tear duct surgery (DCR).
While many tear-duct blockages in children resolve spontaneously or via probing/dilation, in some cases of persistent nasolacrimal duct obstruction beyond infancy, surgery may be needed. The approach may differ and timing is important (often after age 12-18 months depending on case).
Surgery may not be recommended (or may be delayed) in:
Before DCR surgery, the following steps are typical:
Below are the general steps of the dacryocystorhinostomy procedure (details vary by approach):
The cost of blocked tear duct surgery (dacryocystorhinostomy) in India can vary depending on: hospital (private vs public), city, surgeon experience, whether general anaesthesia or day-care, use of stents, post-operative stay, and whether there are additional nasal/sinus procedures.
Indicative ranges:
Risks and possible complications of DCR include:
To ensure safety and maximize success:
The surgery is performed by a surgeon experienced in oculoplastic/tear-duct procedures.
Avoid:
Contact your surgeon if:
“I have had a watery eye for almost 2 years… I had DCR surgery … Unfortunately it did not work… I am on waiting list for revision surgery.”

The surgical procedure (DCR) usually takes about 30-60 minutes, depending onthe approach. For example, external DCR may take ~45-50 minutes, and endoscopic around ~30 minutes in first-time cases.
DCR = Dacryocystorhinostomy (creating a new tear drainage route). DCT = Dacryocystectomy (rarely used; removal of the lacrimal sac) which is not standard for tear-drainage restoration. So yes, they differ.
Discomfort is usually mild. Anaesthesia ensures you don’t feel pain during surgery. Afterward there may be mild bruising, swelling or nasal crusting. Pain is typically manageable with simple analgesics.
Watering may persist for some time because healing is ongoing, the stent may still be in place, or the new passage may be narrower while tissue remodelling occurs. If watering persists longer-term, it could indicate blockage of the new channel or other contributing factors (e.g., canalicular disease).
DCR is considered a safe and commonly performed surgery. Though any surgery has risks (bleeding, infection, failure), the risk is relatively low when performed by experienced surgeons and with proper care.
Most patients are up and about within a few days. Sutures may be removed at 7-10 days. Full return to normal activities (avoiding strenuous work) within 1-2 weeks. Final healing (bone/ostium maturation) may take several weeks to months.
Indicative cost in India: approx ₹40,000 to ₹90,000 (for standard external DCR) and possibly ₹80,000 to ₹1,50,000+ for more complex, revision, endoscopic procedures. Confirm with your hospital.
Yes — external DCR uses a small skin incision, but for most people the scar is small (1-2 cm) and heals to a fine pale line, often in the crease beside the nose/glasses line. In endoscopic DCR there is no external incision, so no visible scar.
In children, many tear duct blockages resolve with less invasive measures (massage, probing). Surgery such as DCR may be considered if blockages persist beyond infancy or if there are anatomical issues. The timing and approach differ.
Yes. Revision DCR is possible for patients whose first DCR fails (due to closure of the new channel, scar formation, stent issues). Success rates for revision may be lower and the surgery may be more complex. > “Scar tissue healed and blocked the path … need date for revision surgery.”
