Summary

Microscopic punctoplasty effectively manages epiphora from punctal stenosis. This surgical technique preserves lacrimal anatomy, offering excellent long-term results with minimal side effects for patients experiencing excessive tearing.

Area of Science:

  • Ophthalmology
  • Oculoplastics
  • Lacrimal Surgery

Background:

  • Epiphora due to punctal stenosis poses a management challenge.
  • Existing treatments may disrupt lacrimal excretory anatomy.

Purpose of the Study:

  • To describe a novel surgical procedure for punctal stenosis.
  • To evaluate the long-term efficacy and safety of microscopic punctoplasty.

Main Methods:

  • Twenty-three patients (32 eyes) with punctal stenosis underwent the procedure.
  • Surgical technique involved excision of stenotic puncta and microscopic externalization of the vertical canaliculus.

Main Results:

  • Excellent long-term control of epiphora was observed in most patients.

  • Minimal incidence of dry eye (one patient) managed with lubricants.
  • Recurrent tearing at 2 years in three eyes was successfully managed with dilation.

    • Conclusions:

    • Microscopic punctoplasty offers a successful, anatomy-preserving approach for epiphora management.
    • The procedure demonstrates excellent long-term efficacy and safety for punctal stenosis.
