Two eyes of 2 patients with high astigmatism following penetrating keratoplasty were treated with femtosecond laser-assisted paired arcuate keratotomies in the donor cornea. Outcome measures included best-corrected visual acuity, refraction, keratometry, and topographic findings. The preoperative cylinder was 8.5 diopters (D) in the first case and 7.0 D in the second case. Respectively, the postoperative cylinder improved to 4.9 D after a follow-up of 8 months and to 4.3 D after a follow-up of 7 months. Best-corrected visual acuity improved from 20/100 to 20/30 in the first case and from 20/200 to 20/60 in the second case. No complications were encountered; no microperforations were observed, and neither graft rejection nor failure occurred.The results of astigmatic keratotomy performed with femtosecond laser were reliable and predictable. Femtosecond astigmatic keratotomy may prove to be a safe procedure with satisfactory results.
