Dacryocystorhinostomy DCR is surgery to create a new pathway between the tear sac and the nose when the main tear duct is blocked. Success rates are generally high, especially when the rest of the drainage system is healthy.
What influences success
Success usually means watery eyes and infections improve or resolve. Several factors affect this outcome.
- External and endoscopic DCR approaches both report success in most patients
- Good healing around the new opening helps it stay patent long term
- Nasal anatomy, scarring, or sinus disease can reduce success rates
- Post-operative care such as nasal sprays and cleaning supports healing
Understanding expectations
Even with excellent surgery, some people still notice mild watering. Honest discussion beforehand helps align expectations.
- Repeat procedures or revision may be needed if the opening narrows
- Stents are often placed temporarily to keep the channel open
- Regular follow-up allows early treatment of any closure or infection
- Most people experience meaningful relief from recurrent sticky, infected eyes
