Abstract Purpose: To evaluate the nasolacrimal duct reconstitution with radio frequency for restoration of lacrimal flow in cases of nasolacrimal duct obstruction.Methods: The procedure was carried out in 16 eyes of 16 patients (13 women and 3 men) by the same surgeon, with monopolar high-frequency device at 450 kHz and 150 W, with local anesthesia under sedation. Inclusion criteria were lower lacrimal system obstruction (confirmed by dacryocystogram) and age over 18 years old. Exclusion criteria were previous trauma, acute dacryocystitis, cutaneous fistula, mucocele, previous lacrimal surgery and cardiac pacemaker.Results: Patients were followed for at least 120 days, patients were clinically evaluated at outpatient clinics for the presence of secretion, epiphora, reflux at compression of the lacrimal sac, placement of silicone tube and Milder test. At the 90-day postoperative visit, 13 patients had positive irrigation (81.25%) with clearance of lacrimal duct and 3 cases (18.75%) presented irrigation failure.Conclusion: Nasolacrimal duct reconstitution with radio frequency was effective in treating nasolacrimal duct obstruction.
