Dacryocystorhinostomy (DCR) is a surgical procedure designed to treat blocked tear ducts. This blockage can cause excessive tearing, infections, or discomfort. During the surgery, a small opening is created between the lacrimal sac (where tears collect) and the nasal cavity to allow tears to drain properly. The procedure can be performed using traditional methods or minimally invasive techniques, such as endoscopy. Recovery typically involves managing discomfort and avoiding strenuous activities. DCR is generally safe and effective, providing relief for patients suffering from chronic tear duct obstructions.
