Impact of donor graft quality on deep anterior lamellar Keratoplasty (DALK)
BACKGROUND To evaluate main features of donor tissue that may influence clinical outcome or complication rate after deep anterior lamellar keratoplasty (DALK). METHODS Donor tissue parameters of 84 consecutive corneal donor grafts used for big-bubble DALK surgery between June 2011 and December 2014 in 84 eyes of 84 patients with disorders of anterior corneal stroma were correlated to clinical...
متن کاملdonor graft quality used for penetrating keratoplasty versus deep anterior lamellar keratoplasty
deep anterior lamellar keratoplasty (dalk) has recently been introduced as an alternative procedure to penetrating keratoplasty (pk) for corneal pathologies not affecting the corneal endothelium. dalk does not rely on donor endothelium and requires less rigid criteria for donor corneal tissue quality. therefore, dalk makes it possible to use donor corneas deemed unsuitable for pk. furthermore, ...
متن کاملRisk Factors for Failure of Keratoplasty in Keratoconus: Penetrating vs. Deep Anterior Lamellar Keratoplasty
Purpose: To determine the etiologic factors on rejection and failure rates and ocular surface changes after corneal transplantation by either DALK or PKP, in cases of keratoconus (KCN). Methods: In this cross-sectional study, considering the existing data, patients with keratoconus referring to Labbafinejad Medical Center from 2006 to 2016, who underwent corneal transplantation, were enrolled a...
متن کاملManual Deep Anterior Lamellar Keratoplasty
Keratoplasty is considered the most successful organ transplantation procedure in the world. Reisinger was the first to use the term keratoplasty (Reisinger, 1824), when he suggested using an animal’s eye to provide donor corneal tissue for corneal transplantation in a human. In 1906, the first successful penetrating keratoplasty was performed by Edward Konrad Zirm on a patient suffering from b...
متن کاملOptimising deep anterior lamellar keratoplasty (DALK) using intraoperative online optical coherence tomography (iOCT)
BACKGROUND/AIMS To describe the use of intraoperative online optical coherence tomography (iOCT) for improving deep anterior lamellar keratoplasty (DALK) surgery. METHODS Retrospective case series of 6 eyes of 6 male patients with keratokonus, corneal dystrophy or herpetic stromal scars undergoing DALK were investigated using intraoperative optical coherence tomography and postsurgical image/...
