Abstract Details


To retrospectively evaluate the clinical outcomes of femtosecond laser-assisted penetrating keratoplasty with Zig-Zag cutting profiles (FKP), conventional keratoplasty (KP), and deep anterior lamellar keratoplasty (DALK).


Department of Ophthalmology, Dokkyo Medical University shool of Medicine


We retrospectively evaluated the clinical records of keratoconus patients who underwent FKP, DALK, or KP between January 2004 and December 2014. The main outcome measures included best-corrected visual acuity (BCVA), endothelial cell density (ECD), and the spherical equivalence. Postoperative data among the three groups were evaluated at postoperative 1, 3, 6, 12, and 24 months.


Fifty-two patients (56 eyes) underwent FKP (8 eyes), DALK (24 eyes), or PK (24 eyes). At the 1-year follow-up, the KP group (-2.5 ± 3.9) had a higher incidence of hyperemic changes of spherical equivalence than did the DALK group (-5.9 ± 4.7), and the FPK group (-5.3 ± 4.0). However, there was no statistically significant difference among the groups. Final BCVA was not different in the groups. However, the FKP achieved earlier statistically improved BCVA than did the other surgical techniques. The ECD changes after FKP were not different from KP.


FPK achieves similar ECD changes as does KP, and is similar to the myopic refractive effects of DALK. However, KP achieves the earliest postoperative visual recovery.
