Prospective comparison of 3 dacryocystorhinostomy surgeries: external versus endoscopic versus transcanalicular multidiode laser.

Purpose: To analyze the clinical outcomes of external (EX-), endoscopic (EN-), and transcanalicular multidiode laser (TC-) with dacryocystorhinostomy (DCR).

Primary outcome measures were the anatomical and functional success of operations at the last control examination.
