Endothelial keratoplasty is at present the gold standard for surgical treatment of corneal endothelial pathologies not associated with significant corneal scar. Tremendous progress has been made in recent years in improving the technology of endothelial keratoplasty techniques, such as descemet stripping automated endothelial keratoplasty (DSAEK) and descemet membrane endothelial keratoplasty. In this review, we discuss the current techniques and outcomes of DSAEK.

Purpose: This study aimed to describe a novel technique of direct anterior chamber (AC) air replacement (DACAR) for the management of Descemet stripping automated endothelial keratoplasty (DSAEK) in postvitrectomized eyes and eyes with previous glaucoma surgery.
Methods: DACAR was performed after a corneal donor graft was transplanted through a wound using the pull-through technique. DACAR involves stabilizing the graft with forceps while introducing air into the AC via an infusion cannula to ensure complete air exchange.

Aim: This study aimed to evaluate the impact of pterygium excision combined with autologous limbal stem cell transplantation on microvascular density, tear film stability, and corneal wound healing in the management of pterygium.
Methods: A retrospective analysis was conducted on 317 patients with pterygium who underwent treatment between January 2021 and January 2024. Patients were divided into a control group (pterygium excision alone, n = 161) and a study group (pterygium excision combined with autologous limbal stem cell transplantation, n = 156) based on the surgical approach.

A first-in-human investigator-initiated clinical study of a corneal endothelial cell substitute (CLS001) derived from a clinical-grade induced pluripotent stem cell (iPSC) line shows improvement of visual acuity and corneal stromal edema, with no adverse events for up to 1 year after surgery for the treatment of bullous keratopathy. While preclinical tests, including multiple whole-genome analysis and tumorigenicity tests adhering to the Food and Drug Administration (FDA) draft guidelines, are negative, an additional whole-genome analysis conducted on transplanted CLS001 cells reveals a de novo in-frame deletion of exon22 in the EP300 gene. No adverse events related to the mutation are observed.

Purpose: Describe aims, methods, characteristics of donors, donor corneas and recipients, and potential impact of the Diabetes Endothelial Keratoplasty Study (DEKS).
Methods: The DEKS is a randomized, clinical trial to assess graft success and endothelial cell density (ECD) 1 year after Descemet membrane endothelial keratoplasty (DMEK) using corneas from donors with versus without diabetes in a 1:2 minimization assignment. Diabetes severity in the donor is assessed by medical history, postmortem HbA1c, and donor skin advanced glycation end-products and oxidation markers.
