Follow up of Nasolacrimal Intubation in Adults

For patients with chronic epiphora, Dacryocystorhinostomy is currently the gold standard treatment, with a success rate of 80-90% according to literature. Another available treatment, which is far less used, in nasolacrimal intubation, using a silicone tube. In our study, we would like to find the efficacy of nasolacrimal duct intubation, which was performed in our medical center on a few hundred patients with mild epiphora. Study hypothesis: nasolacrimal intubation in adults, with a clinically mild epiphora, is close in it's efficacy to the Dacryocystorhinostomy procedure.
