Sutured Descemet Membrane Endothelial Keratoplasty in Patients With Complex Anatomy or Difficulty Positioning.

ABSTRACT:

Purpose

In Descemet membrane endothelial keratoplasty (DMEK), some patients cannot adhere to postoperative positioning requirements or lack anatomic support for a gas bubble in the anterior chamber. We describe a suturing technique that stabilizes the graft postoperatively without tearing or tenting it.

Methods

One to two 10-0 nylon sutures with a spatulated needle are used to secure DMEK grafts. Tied with minimal tension, the sutures traverse the corneal stroma at a steep, almost perpendicular angle and approach the graft from the limbus at an angle tangential to the circular graft to prevent vaulting the tissue off the central cornea. We report preoperative and postoperative best spectacle-corrected visual acuity, corneal pachymetry, and anterior segment optical coherence
