F66 Femtosecond Laser–Assisted DSAEK: Easier and Safer Technique

Descemet-stripping automateed endothelial keratoplasty requires use of expensive precut tissue or assembly of the graft by a mechanical microkeratome.  Both techniques may result in donor tissue damage. The Descemet-stripping step of the recipient may be traumatic and lead to upregulation of stromal keratocytes, facilitating later rejection. The added thickness of the implanted tissue may also lead to difficulty in clearing the corneal edema. The femtosecond laser eliminates these challenges.
