ABSTRACT To describe traction retinal detachment as a complication of posterior dislocation of Descemet stripping automated endothelial keratoplasty (DSAEK) graft.
Vitrectomy surgery was performed in 3 eyes that developed posterior dislocation of DSAEK graft. Intraoperatively, the corneal tissue was found to be adherent to the retina. In 2 cases, a retinal detachment with proliferative vitreoretinopathy (PVR) was already present and the donor DSAEK flap was found to be fused with the retina. In 1 case, the retina was attached at the time of surgery but PVR subsequently developed despite near total removal of the graft, requiring an additional procedure to achieve retinal reattachment.
Corneal tissue removal with a vitreous cutter was attempted in all cases. Residual tissue that had fused with the retina was left in place. Retinal reattachment was achieved with silicone oil injection in 2 cases and scleral buckle alone in 1 case.
Posterior segment dislocation of a DSAEK flap and its adherence to the retina may cause PVR and traction retinal detachment. Early removal is warranted when dislocation occurs.

    ABSTRACT: Descemet's stripping automated endothelial keratoplasty (DSAEK) has become the preferred surgical treatment for corneal endothelial pathologies. An intraoperative complication of DSAEK is posterior dislocation of the donor graft into the vitreous cavity. As the number of performed DSAEK procedures grows each year, the possibility of encountering a posteriorly dislocated donor graft increases. The authors report a case of intraoperative graft dislocation and a novel hand-over-hand retrieval method from the retinal surface. The hand-over-hand method provides an added surgical strategy for rescuing grafts that have fallen into the vitreous cavity. [Ophthalmic Surg Lasers Imaging Retina. 2013;44:xxx-xxx.].

    ABSTRACT: To describe changes in the surgical technique required for combining Descemet membrane endothelial keratoplasty with glued intrascleral haptic fixation of a posterior chamber intraocular lens ([IOL] glued IOL) as a single-stage surgery in patients diagnosed as having aphakic or pseudophakic bullous keratopathy.

    ABSTRACT: To describe the complication rate and type of intraoperative and postoperative complications of Descemet stripping endothelial keratoplasty (DSEK). Retrospective medical records review of patients who underwent DSEK between 2008 and 2010 at the Sorocaba Ophthalmological Hospital. The study was descriptive, using a quantitative approach. One hundred nineteen eyes of 118 patients were evaluated. According to the diagnoses, most patients were diagnosed with Fuchs' dystrophy (60 eyes, 50.4%), followed by patients with pseudophakic bullous keratopathy in 55 eyes (46.2%). The most common procedure performed was DSEK alone, performed in 65 eyes (54.6%), followed by the DSEK associated to phacoemulsification (PHACO-DSEK) in 47 eyes (39.5%) and DSEK associated to other surgeries (7 eyes, 5.9%). Eight patients were excluded from the study due to insufficient information in the surgical record. In relation to the intra-operative complications, isolated cases of pupillary block, irregular manual dissection of button, inverted implantation of the button, button-holing and posterior capsule rupture were noticed. Among the documented early postoperative complications, button detachment was observed in 21.5% of the DSEK alone group; 34.0% in PHACO-DSEK group and 57.1% when DSEK was held jointly with other surgical techniques. Regarding to late complications, interface haze was observed in 16.9%, 8.5% and 14.2%, and glaucoma was observed in 4.6%, 2.1% and 14.2% in DSEK, PHACO-DSEK and DSEK associated to other techniques, respectively. Post rejection graft failure was observed in 15.3% and 12.7% of the eyes after DSEK and. PHACO-DSEK, respectively. Endothelial corneal transplant accomplished in this sample showed a high rate of complications when compared to the conventional penetrating keratoplasty. The most frequent complications were related to detachment of the button and graft failure.
