Purpose: Does perioperative use of Rho-Kinase (ROCK) inhibitors have beneficial effect on corneal endothelial cells after phacoemulsification? SETTING: This study was conducted at King Abdulaziz University Hospital in Riyadh.
Design: This was a prospective study assessing the effect of ROCK inhibitors on corneal endothelium after phacoemulsification.
Methodology: Three patients have used ROCK inhibitor 1 day before and 1 week after phacoemulsification surgery, and specular microscopy and Pentacam were done preoperatively and 3 months postoperatively.
Results: Endothelial cell density decreased to 11.3%, 9.45%, and 4.09% in eyes with ROCK inhibitors and 23.9% in one eye without ROCK inhibitor.
Conclusion: Perioperative ROCK inhibitor use has a possible protective effect on corneal endothelium.

Fuchs Endothelial Corneal Dystrophy (FECD) is the most frequent indication for corneal transplantation, with Descemet membrane endothelial keratoplasty (DMEK), Descemet stripping automated endothelial keratoplasty (DSAEK), and penetrating keratoplasty (PK) being viable options. This retrospective study compared 10-year outcomes of these techniques in a large cohort of 2956 first-time keratoplasty eyes treated for FECD at a high-volume corneal transplant center in Germany. While DMEK and DSAEK provided faster visual recovery (median time to BSCVA ≥ 6/12 Snellen: DMEK 7.

To observe the characteristics of ocular biological parameters in children with transfusion-dependent β-thalassemia (TDT) and the effect of iron chelator treatment on them. This was a cross-sectional study. Thirty-two children with TDT (TDT group) and 64 healthy children (control group) who were treated in the Affiliated Hospital of Guangdong Medical University from October 2022 to June 2023 were included.

Corneal blindness is a significant reason for visual impairment globally. Researchers have been investigating several methods for corneal regeneration in order to cure these patients. Biomaterials are favored due to their biocompatibility and capacity to promote cell adhesion.

Fuchs' endothelial corneal dystrophy (FECD) is a common sight-threatening condition characterised by pathological changes in the posterior cornea. Here we report observations by light, transmission and volume scanning electron microscopy on changes in the endothelium and matrix associated with the characteristic deformations of Descemet's membrane, termed guttae. Specimens were archived full-thickness human corneal tissue, removed during graft surgery, that had been fixed, stained and embedded by conventional processing methods for examination by transmission electron microscopy more than 40-years previously.
