Comparing Clinical Outcomes of Descemet’s Membrane Stripping Automated Endothelial Keratoplasty Between Graft Insertion Methods

Purpose: To compare clinical outcomes of Descemet’s stripping automated endothelial keratoplasty (DSAEK) between different graft insertion methods Methods: The clinical records of 32 eyes of 30 DSAEK patients were retrospectively analyzed. Patients were divided into 2 groups according to graft insertion method. Group A: Taco-folding, group B: Tan-endoglide. The best corrected visual acuities (BCVA), intraocular pressures, astigmatism, endothelial cell count, central corneal thickness and complications were evaluated pre and post-operatively. Results: The average follow-up period was 19 months (range 1-67). Postoperative log MAR visual acuity had significantly improved both from 1.63 (log MAR) to 0.69 and 0.53 at 12 months in each group (p = 0.035, p = 0.000). Mean endothelial cell survival of each group at 1 month postoperative were 75.8% (range 62.7-88.6) and 87.7% (range 70.2-97.9), respectively (p = 0.012). The differences of BCVA improvement and endothelial cell survival between the groups at 12 months were not significant (p = 0.393, p = 0.544). Conclusions: Both methods showed fast visual recovery. Using Tan-endoglide insertion resulted less endothelial cell loss at early post-operative period and showed less post-operative complication and graft failure.
