Tear Duct Surgery

Types of Tear Duct Surgery

1. External Dacryocystorhinostomy (DCR)

• A small incision is made near the inner corner of the eye to create a new drainage passage.
• A tiny stent (tube) may be placed to keep the passage open.
• Leaves a small, barely visible scar but has a high success rate.

2. Endoscopic DCR (Scarless Surgery)

• A minimally invasive procedure performed through the nose using an endoscope.
• No external incisions or scars.
• Faster healing and less discomfort compared to external surgery.

3. Balloon Dacryoplasty (For Partial Blockage)

• A tiny balloon catheter is inserted and inflated to widen the blocked tear duct.
• A quick, non-surgical alternative for mild cases.

4. Tear Duct Intubation (Stenting)

• A small silicone tube is inserted to keep the tear duct open.
• Often used for infants or patients with mild obstruction.

How the Surgery is Performed

1. Pre-Surgical Preparation

• Eye and nasal exams, including imaging tests (CT scan or dye test) to assess the blockage.
• Local or general anesthesia is administered.

2. Surgical Procedure

• The surgeon creates a new drainage pathway between the tear sac and the nose.
• In some cases, a temporary stent is inserted for healing.
• The procedure takes 30-60 minutes.

3. Recovery and Healing

• Patients can go home the same day (outpatient procedure).
• Minor swelling or bruising may occur but resolves within a week.

Post-Surgery Care and Recovery

• Use prescribed eye drops and antibiotics to prevent infection.
• Avoid rubbing the eyes for a few weeks.
• Apply cold compresses to reduce swelling.
• Do not blow your nose forcefully for 1-2 weeks.
• Follow up with your doctor to check healing and remove any stents.

Potential Risks and Complications

• Mild bleeding or bruising around the eye.
• Infection at the surgical site (rare but possible).
• Scar formation (if external surgery is performed).
• Blockage recurrence, requiring further treatment.

Tear duct surgery is a highly effective treatment for blocked tear ducts, restoring normal tear drainage and preventing chronic infections. With advances in endoscopic and minimally invasive techniques, patients can achieve fast recovery and excellent results, improving both eye comfort and vision clarity.
