Corneal Densitometry After Uneventful Descemet Membrane Endothelial Keratoplasty—5-Year Outcomes

Purpose: The purpose of this study is to analyze the course of corneal densitometry (CD), endothelial cell density (ECD), best-corrected visual acuity (BCVA), and central corneal thickness (CCT) 5 years after uneventful Descemet membrane endothelial keratoplasty (DMEK). Methods: Sixty uneventful cases (51 patients) with a minimum follow-up of 5 years were included. CD of various corneal layers (anterior, central, posterior, and total layer) and zones (0–2 mm, 2–6 mm, and 6–10 mm) were measured with Scheimpflug tomography. ECD, BCVA, and CCT were also evaluated. Results: Total CD at 0 to 2 mm and 2 to 6 mm zones significantly decreased from 33 ± 10 and 27.8 ± 8 grayscale units (GSU) preoperatively to 21.8 ± 3.1 and 22.2 ± 4.2 GSU at 5 years, respectively (P
