    The safety and efficacy of a novel technique combining partial wound resuturing and crosslinking (CXL) for severe postkeratoplasty astigmatism will be demonstrated. Keratoconus eyes with severe postkeratoplasty astigmatism treated with wound resuturing combined with CXL are demonstrated herein. Wound exposure of 90% depth and at least 180 degrees, followed by interrupted-suture closure and simultaneous 0.25% riboflavin solution soaking and eventually 30 mW/cm² for 4.5 minutes (total 7.2 Joules) UV CXL. Uncorrected and corrected distance visual acuity (UDVA, CDVA), endothelial cell density (ECD), refraction, topography, Scheimpflug tomography and OCT-based data will be shown as well, resulting in mean value changes as follows: UDVA from 20/200 to 20/60; CDVA from 20/60 to 20/25; ECD, unchanged and cylinder from 8.5 to 2.5 D. All corneal imaging documented improved normalization
