Summary

This modified non-penetrating deep sclerotomy (NPDS) technique uses fewer sharp instruments, offering satisfactory results and a shorter learning curve for glaucoma surgeons.

Area of Science:

  • Ophthalmology
  • Glaucoma Surgery
  • Surgical Techniques

Background:

  • Non-penetrating deep sclerotomy (NPDS) is a glaucoma surgical procedure.
  • Minimizing sharp instrument use in NPDS can potentially reduce complications.

Purpose of the Study:

  • To introduce a modified NPDS technique.
  • The modification aims to limit the use of sharp instruments during the procedure.

Main Methods:

  • A modified NPDS technique was employed using specialized spatulas to protect Descemet's membrane.
  • The procedure was performed on 66 patients with primary open-angle or pseudo-exfoliative glaucoma.
  • The surgery was conducted by one experienced surgeon and three surgeons transitioning to the technique.

Main Results:

  • Only two microperforations (3%) of Descemet's membrane occurred intraoperatively, requiring no special treatment.
  • Postoperative complications included transient hypotony and one case of choroidal detachment.
  • Intraocular pressure (IOP) control was satisfactory, with mean IOP of 9.6 mmHg post-surgery and 14.6 mmHg at one year.

Conclusions:

  • The modified NPDS technique yielded satisfactory results with minimal complications.
  • This modified approach is recommended for surgeons new to NPDS, potentially shortening the learning curve.
