Endoscopic dacryocystorhinostomy (DCR) is a minimally invasive procedure used to treat blocked tear ducts, a condition that leads to excessive tearing or chronic eye infections. The procedure involves creating a new drainage pathway from the lacrimal sac to the nasal cavity using an endoscope, which is inserted through the nose, avoiding the need for external incisions.

Endoscopic DCR is highly effective in restoring normal tear drainage, alleviating symptoms such as excessive tearing, and preventing recurrent infections. It is typically performed on an outpatient basis and requires a short recovery time.

This procedure is an excellent option for patients with chronic tear duct obstructions, providing a minimally invasive solution with reduced risks and faster recovery.
