The bicanalicular stent that was used was about 40-cm in length, made up of biological grade silicone with stainless steel probes at both the ends [Figure 1].

One end of the bicanalicular silicone stent was passed through the superior punctum under direct vision [Figure 2].

It was then passed through the avulsed end of the NLD and further into the canal [Figure 3].

The length of the bicanalicular stent was adjusted between the superior and inferior punctum to prevent tension before tying the two ends securely [Figure 5].
