Biocompatibility of Genetically‐Engineered Pig Cornea in Corneal Xenotransplantation: Preliminary In Vitro Study

Xenotransplantation, Volume 32, Issue 5, September/October 2025.
ABSTRACT Introduction We aimed to evaluate biophysical compatibility of corneal endothelial cells in genetically‐engineered (GE) pigs to identify the best candidate for in vivo nonhuman primate (NHP) study and to collect baseline data for future clinical trials from a biological function perspective.

Extremely asymmetric ectasia: Tomographically unilateral keratoconus

Acta Ophthalmologica, Volume 103, Issue 5, Page 530-538, August 2025.
Abstract Purpose To investigate the characteristics of apparently stable forms of tomographically unilateral keratoconus (KC). Methods In this retrospective case–control study, strict unilaterality criteria were applied to select tomographically unilateral cases with ≥3 years of follow‐up.
