Thickness of the lamellae measured in the eye bank can be taken to define it as ultrathin or conventional DSAEK. In tissue bank, the lamellae are usually measured by ultrasound pachymetry, which is the gold standard for corneal thickness measurement.
In a select group of patients with soft eyes that had undergone trabeculectomy, our preliminary results indicate that judicious use of OVD into the bleb may enhance DSAEK graft adherence to the host stroma and reduce risk of postoperative graft detachment.
Covert and Koenig reported a prospective surgical case series of 7 eyes of 7 consecutive patients undergoing DSAEK for graft failure after PKP .
According to the published literature, the femtosecond laser created corneal flaps with better predictability than mechanical microkeratomes.,,,, Other studies have shown that the femtosecond laser could be used for the preparation of the endothelial graft for femtosecond laser-assisted DSAEK.,,, With the assistance of the femtosecond laser, surgeons can produce ultrathin corneal endothelial grafts, which will possibly result in better clinical outcomes.
In contrast to PK, where all layers of the host cornea are replaced, DSAEK represents an additive procedure, where a graft consisting of a layer of posterior donor stroma of variable thickness and a layer of healthy corneal endothelium is placed on the posterior surface of the host cornea.
DSAEK is usually performed on eyes that are pseudophakic or combined with simultaneous cataract surgery.
Material and Method: Twenty eyes of 20 patients who underwent DSAEK with a diagnosis of PBK in our clinic between September 2010-January 2012 were included in this study.
In this study, we assessed the anatomical and ophthalmic characteristics of the donor grafts and the recipient eyes that underwent DSAEK up to 7 years after surgery.
PK was the only technique applied until 2009, when DSAEK was introduced, starting with 8.9% (2009) and reaching 59.9% (2015) (Figure 5).
In first instance, the surgical complexity (e.g., because of the thinner tissue used, graft unfolding can be more challenging) and its steep learning curve discourage many surgeons from leaving DSAEK in favor of this technique [9-11].
