Erbium-YAG laser canalicular plastic surgery effectively treats stenosis, with 86% of patients showing improvement. This minimally invasive laser treatment offers a successful alternative for canalicular stenosis.

Area of Science:

  • Ophthalmology
  • Laser Surgery
  • Lacrimal System Anatomy

Background:

  • Canaliculus stenosis can cause significant epiphora.
  • Conventional surgical methods for canalicular stenosis have limitations.

Purpose of the Study:

  • To evaluate the efficacy of erbium-YAG laser canalicular plastic surgery for treating symptomatic canalicular stenosis.
  • To compare laser treatment outcomes with conventional surgical approaches.

Main Methods:

  • A total of 44 patients with symptomatic canaliculus stenosis were treated using an erbium-YAG laser.
  • Laser treatment involved a sapphire fiber, and endoscopic diagnosis was performed before and after.
  • Patient outcomes were assessed via questionnaires and follow-up examinations after an average of 12 months.

Main Results:

  • The success rate for reducing epiphora was 67%.
  • Overall, 86% of patients reported an improvement in their canaliculus communis stenosis.

Conclusions:

  • Laser canalicular plasty using the erbium-YAG laser is a highly effective minimally invasive surgical treatment.
  • This method is particularly suitable for point-focal, noninflammatory canalicular stenosis.
