Descemet stripping automated endothelial keratoplasty after failed penetrating keratoplasty.

Purpose: To report the rate of graft dislocation, surgical anatomic success, and postsurgical complications associated with Descemet stripping automated endothelial keratoplasty (DSAEK) after previous primary failed penetrating keratoplasty (PK).

Methods: Institutional review board-approved, single-center, retrospective chart review study of 30 eyes of 30 patients with prior failed PK who underwent DSAEK with a minimum of 3 months follow-up. Primary outcomes measured included rates of anatomic success and failure, postoperative complications, lenticle size, visual acuity, intraocular pressure change, and a report of external factors that may affect success.
