To understand the procedure, let's first understand how the tear drainage system works. Normally, tears wash the eye and then drain through tiny openings (puncta) in the inner corner of the eyelids into the lacrimal sac, and from there, down the nasolacrimal duct into the nasal cavity. This is why we get a runny nose when we cry. If the nasolacrimal duct becomes blocked for any reason (due to inflammation, trauma, or congenital issues), tear drainage is obstructed. This leads to persistent tearing (epiphora) and dacryocystitis (infection of the lacrimal sac).
Dacryocystorhinostomy (DCR) is a microsurgical operation aimed at creating a new bypass for tears to drain from the lacrimal sac directly into the nasal cavity, bypassing the blocked nasolacrimal duct. Laser-assisted endoscopic DCR is the most modern, minimally invasive, and aesthetic way to perform this surgery through the nose, avoiding facial scars.

The surgery is performed under anesthesia and is completely painless. Postoperatively, pain is generally absent or minimal and is easily relieved by standard pain medications, which are often not even required.
