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.

    DSAEK has recently evolved as a preferred method in place of PKP. After DSAEK, we experienced subconjunctival emphysema, decreased air bubble in the AC and low IOP. This could lead to complications, higher rate of dislocation or infection. We should control the wound closure with suture when in...
