Lacrimal stenting versus three-snip punctoplasty for treatment of punctal stenosis or occlusion: an open- label, randomized clinical trial.

Background: To compare the short-term anatomical and functional outcomes of, as well as patient satisfaction with, lacrimal stenting and three-snip punctoplasty for the treatment of punctal stenosis or occlusion.

Methods: In this open-label, randomized clinical trial, we included 50 eyes of 30 patients diagnosed with punctal stenosis or occlusion. They were randomly allocated to two groups of 25 eyes each, using central telephone randomization.
