Effects of an autostable bicanaliculus intubation stent in the management of acquired punctal stenosis

Comparison between three snip punctoplasty and silicone tube stent in patients with primary punctal stenosis

“…experienced premature spontaneous stent loss between the first week and the 2-month follow-up. One patient (5%) had persistent epiphora20 .According to Al-study, Taher's 33 (82.5%) of 40 eyes had self-retaining bicanaliculus intubation set for the treatment of acquired punctal stenosis, and five (12.5%) of those 40 eyes experienced premature stent loss.One of the main issues is the prolapse or loss of the lacrimal stent, which may require replacement. Long-term intubation can cause further problems, such as secondary bacterial or fungal infections, punctal or ostium granulomas, excessive bicanalicular stent loop tightening or inferior strain, punctal or ostium cheese wire, and, in rare cases, corneal erosions and infections21 .In the current study, in group 1, two cases suffered from recurrence of epiphora due to re-stenosis of the punctum (10%) after 3 months of punctoplasty while only one case (5%) suffered from recurrence of epiphora in group 2 due to restenosis after 5months of silicone intubation without a difference between the two groups that was statistically significant (p=0.548).…”
