Graft is pre-cut in the eye bank with automated microkeratomes because manual preparation of endothelial grafts proved to be a difficult and time consuming procedure (5).
According to the published literature, the femtosecond laser created corneal flaps with better predictability than mechanical microkeratomes.[6],[7],[8],[9],[10] Other studies have shown that the femtosecond laser could be used for the preparation of the endothelial graft for femtosecond laser-assisted DSAEK.[11],[12],[13],[14] With the assistance of the femtosecond laser, surgeons can produce ultrathin corneal endothelial grafts, which will possibly result in better clinical outcomes.
IntraLase femtosecond laser vs mechanical microkeratomes in LASIK for myopia: a systematic review and meta-analysis.
Many microkeratomes tend to cut deeper in the periphery, and since the cornea is deeper in the periphery, this can result in a relatively planar central donor lenticule [21].
Originally introduced as an alternative to mechanical microkeratomes for creating LASIK flaps, a new generation of femtosecond laser has emerged that reaches deeper into the eye, to depths of 7500[micro]m, providing uses in cataract extraction procedures.
(32) However, other studies have not shown significant differences in the visual outcomes between mechanical microkeratomes and creation of the flap using the femtosecond laser.
First, technology has continued to improve since the first generation of lasers and microkeratomes, giving better results, which in turn encourages more doctors to endorse or perform the procedure.

LASIK flaps created using mechanical microkeratomes can on occasion be sub-optimal, incomplete, become "free', or have a "button-hole', which is distressing for the patient.
