Purpose To compare postoperative astigmatism outcomes of femtosecondlaser‐assisted 110°‐cut PK (FLPK) with conventional PK (PK)in keratoconus patients. Methods 62 keratoconus patients were divided into 2 groups: FLPK‐32 patients, PK‐30 patients. Procedures were done with femtosecondlaser‐assisted 110°‐cut with outer diameter of donor's cornea 8.0 mm, in conventional PK donor's graft diameter was also 8.0 mm. Postoperative astigmatism, BCVA, endothelial cell loss were evaluated. Results Follow‐up was at least 6 months. Postoperative astigmatism was lower in FLPK group (2,1±0,5D versus 4,19±1,7D in PK group, p<0.05). BCVA was respectively 0,59±0,1 and 0,55±0,1, endothelial cell loss 30,4±8,3% and 34,1±7,8% respectively. Conclusion Femtosecondlaser‐assisted surgery results in lover astigmatism level
