Exponential curve fitting regression model in non-Fuchs patients who underwent penetrating keratoplasty and cataract surgery. (A) The mean rate of endothelial cell loss was 19.43% per year with statistical significance, while the loss rate was 29.27% per year in group C (Fuchs corneal dystrophy patients who underwent keratoplasty and cataract surgery simultaneously). (B) The mean rate of pachymetric change was +0.13% per year, and in contrast, +1.89% per year in group C. (C) The mean rate of coefficient of variances change was +1.21% per year, and +0.48% per year in group C. (D) The mean rate of hexagonality change was -0.48% per year and -1.19% per year in group C. ECC = endothelial cell count.
