The influence of speed during stripping in descemet membrane endothelial keratoplasty tissue preparation
Cornea Aug 09, 2020
Borroni D, Gadhvi K, Wojcik G, et al. - This study was undertaken to determine if the speed of stripping a Descemet membrane endothelial keratoplasty graft influences the graft scroll width. Pairs of corneas were randomly divided into two groups: 1 cornea was stripped with a slow speed, defined as the total time greater than 150 seconds or speed <0.057 mm/s, (group 1) and the contralateral with a fast speed (group 2). The study included 20 corneas of 10 donors, mean donor was 68.6 ± 7.58 years. A correlation was found between the speed of stripping, scroll width, and endothelial cell loss. Slow-peeled Descemet membrane endothelial keratoplasty grafts result in a wider scroll width but have been linked to a greater decline in endothelial cell density.
