Purpose: To identify determinants of corneal endothelial cell density at 12 months after Descemet stripping automated endothelial keratoplasty (DSAEK).
Methods: This study included patients with bullous keratopathy who underwent DSAEK with internationally sourced donor corneas from March 2021 to March 2022. We assessed various preoperative factors in recipients (age, cause of bullous keratopathy, intraocular pressure, visual acuity, anterior chamber volume, depth and angle, pupil size, white-to-white corneal diameter, and preoperative corneal endothelial cell density) and donors (age, death to preservation time, preservation to transplantation time, death to transplantation time, corneal endothelial cell density, trephine size, and precut tissue thickness). We analyzed factors influencing corneal endothelial cell density up to 12 months after keratoplasty.
Results: This study involved 53 patients, with an average recipient age of 65.9 ± 14.6 years prior to surgery. Donor corneas had an average endothelial cell density of 2,871.6 ± 271.6 cells/mm2. At 6 and 12 months postoperatively, endothelial cell densities had decreased by 36.9% and 47.2%, respectively, compared with preoperative levels. Multivariate linear regression analysis indicated that endothelial cell densities at 3 and 12 months postoperatively were linked to recipient age and anterior chamber depth.
Conclusions: Corneal endothelial cell density after DSAEK typically stabilized after initial decline; higher densities were found in older recipients and individuals with shallower anterior chambers.
