An alternative method of closed silicone intubation of the lacrimal system

An alternative method of closed lacrimal intubation is described, the basis of which is to place the end of a piece of silicone tubing over the end of a small-diameter metal introducer, stretch the silicone tubing back along the introducer, and then pass the introducer together with the tubing through the lacrimal system into the nasal cavity. The tubing is visualized in the inferior meatus, from where it is retrieved, and then the introducer is withdrawn. The other end of the tubing is passed in a similar fashion. The technique is easily mastered, inexpensive, and less traumatic than other described techniques.
