Abstract

PURPOSE: To prospectively evaluate clinical and visual results of running suture adjustment after keratoplasty. METHODS: Thirty-seven eyes of 33 patients received running suture adjustment after keratoplasty. Changes in uncorrected visual acuity, distance best spectacle-corrected visual acuity (BSCVA), refraction, and Fourier analysis constituents were assessed before and after suture adjustment. RESULTS: Thirty eyes, which had improvement of distance BSCVA soon after suture adjustment, maintained improvement at 1 year, whereas 7 eyes with decreased distance BSCVA soon after suture adjustment experienced no improvement at 1 year. Patients with poor distance BSCVA at 1 year had significantly higher high order irregularity than patients with better distance BSCVA despite similar cylindrical power outcomes. CONCLUSIONS: Astigmatism after keratoplasty can be effectively reduced by suture adjustment.
