PURPOSE: The goal of this study was to evaluate the effect of various Food and Drug Administration-approved storage solutions on endothelial cell density (ECD) and central corneal thickness (CCT).
METHOD: We analyzed 6220 tissues used for endothelial keratoplasty procedures between January 2022 and June 2023 that were stored in either Life4°C, Optisol-GS, Kerasave, or Eusol-C under hypothermic conditions. We analyzed preprocessing CCT, success rate of meeting surgeon's Descemet stripping automated endothelial keratoplasty (DSAEK) thickness preferences, and preprocessing and postprocessing ECD. Results were analyzed using one-way analysis of variance, followed by multiple pairwise comparisons using the Tukey test.
RESULTS: Mean preprocessing CCT was significantly lower in the Life4°C group (532 μm) than in Optisol-GS (549 μm), Kerasave (582 μm), and Eusol-C (589 μm) groups (all P < 0.0001). Preprocessing CCT in the Optisol-GS group was significantly lower than in Kerasave and Eusol-C groups (F (3, 3273) = 153.1, all P < 0.0001). Success rate of meeting surgeon DSAEK preferences was statistically similar among all 4 groups. Preprocessing ECD of the Kerasave group (2821 cells/mm 2 ) was numerically higher than of the Eusol-C (2791 cells/mm 2 ), Life4°C (2759 cells/mm 2 ), and Optisol-GS (2768 cells/mm 2 ) groups ( P = 0.3232, 0.0004, and 0.0015, respectively).
CONCLUSIONS: Corneal tissues stored in Kerasave and Eusol-C are significantly thicker than those in Life4°C and Optisol-GS. However, the success rate of meeting surgeon DSAEK preferences is similar among all 4 storage solutions.
