Abstract
Purpose :
To compare the visual and refractive outcomes after femtosecond laser deep anterior lamellar keratoplasty (FSDALK) and full-thickness femtosecond laser enabled keratoplasty (FLEK) for patients with keratoconus.
Methods :
A retrospective chart review of 33 eyes undergoing FSDALK and 104 eyes undergoing FLEK for keratoconus. Both groups undergoing zig-zag laser incision configuration for the host and donor trephination pattern. Comparing corrected distance visual acuity (CDVA), spherical equivalent (SE), manifest and topographic astigmatism, complications, and graft rejection rates between the two groups.
Results :
Preliminary results suggest no significant difference in CDVA, SE, or topographic astigmatism between the two groups. However, the rate of graft rejection is lower in the FSDALK group. Results will be update prior to presentation.
Conclusions :
CDVA and post-operative astigmatism are similar after FSDALK or FLEK. Overall, FSDALK may have an advantage in patients with Keratoconus given comparable visual outcomes to FLEK with decreased rates of graft rejection rate.
