Dacryocystorhinostomy (DCR) is a surgical procedure used to treat blocked tear ducts, which can cause chronic eye tearing, discomfort, and infection. The procedure involves creating a new drainage pathway from the lacrimal sac (which holds the tears) to the nose, bypassing the blocked duct.

DCR is typically recommended when other treatments, such as massage or antibiotics, have failed to resolve the problem. The surgery can be performed through a small incision in the skin or using an endoscopic approach to minimize scarring.

This procedure can provide long-term relief from tear duct blockage, reducing symptoms such as excessive tearing, and improving overall eye health and comfort.
