By postoperative month 3, mean manifest refractive and topographic astigmatism was 2.31 ± 1.41 D and 2.59 ± 1.57 D, respectively. Results: At one-year follow-up, there was an improvement in unaided visual acuity from a mean preoperative logMAR of 1.67 to 0.44, and best spectacle-corrected visual acuity from a mean preoperative logMAR of 1.33 to 0.13. Outcomes measured included: unaided visual acuity and best spectacle-corrected visual acuity preoperatively and at one, 3, 6, and 12 months postoperatively manifest refractive and topographic astigmatism at 3, 6, and 12 months postoperatively and endothelial cell density loss, calculated at the end of the one-year follow-up period. Femtosecond laser was used to perform a zig-square incision on the donor cornea with matched dimensions on the recipient cornea.
