Dacryocystorhinostomy (DCR) is a surgical procedure to restore the flow of tears into the nose from the lacrimal sac when the nasolacrimal duct does not function.

A Jones or Crawford tube is placed to facilitate the flow of tears from the eye to the nose.

Data suggests a slightly lower success rate than the "traditional" technique.

The medial wall of the sac is incised or excised, facilitating drainage of tears into the nasal cavity.

At a follow-up time of more than six months, antimetabolites may improve functional and anatomic results.
