Tear duct surgery refers to operations that restore or improve drainage of tears from the eye into the nose. Procedures vary depending on the level and cause of blockage.
Main Surgical Options
For complete nasolacrimal duct obstruction in adults, dacryocystorhinostomy (DCR) creates a new passage from the tear sac to the nose. In children or partial blocks, probing, balloon dilatation, or silicone intubation may be used.
- Endoscopic and external approaches exist for DCR
- Eyelid malposition surgery can improve tear pump function when lids are turned in or out
- Punctal plugs can intentionally block drainage in dry eye rather than relieve obstruction
- Choice of procedure depends on imaging, irrigation tests, and symptoms
Goals and Outcomes
The main aim is to reduce troublesome watering and prevent tear sac infections. Success rates are high when the correct level of obstruction is addressed.
- Temporary bruising, swelling, or nasal congestion are common after surgery
- Stents or tubes may remain in place for weeks to months
- Follow-up visits check that the new drainage pathway stays open
- Occasional revision surgery is required if scarring recurs
