    Congenital nasolacrimal duct obstruction (CNLDO) affects approximately 20% of newborns, with a 90% spontaneous resolution rate within the first year.

  • 2

    Treatment for CNLDO initially involves conservative measures, including observation, lacrimal massage, and topical antibiotics.

  • 3

    Probing has a success rate of 70%–97% for CNLDO, while nasolacrimal duct stent insertion shows a success rate of 79%–96%.

  • 4

    This study compares balloon dacryoplasty and bi-canalicular intubation for recurrent epiphora after failed initial CNLDO procedures.

  • 5

    Patients were grouped based on the procedure received, with allocation influenced by the availability of surgical instruments.
