Corneal endothelial cells play a critical role in maintaining corneal transparency and dysfunction of these cells caused by aging, diseases (such as Fuch's dystrophy), injury or surgical trauma, which can lead to corneal edema and blindness. Due to their limited proliferative capacity , the only treatment method is via transplantation of a cadaver donor cornea. However, there is a severe global shortage of donor corneas. To circumvent such issues, tissue engineering of corneal tissue is a viable option thanks to the recent discoveries in this field. In this review, we summarize the recent advances in reprogramming adult human corneal endothelial cells into their progenitor status, the expansion methods and characteristics of human corneal endothelial progenitors, and their potential clinical applications as corneal endothelial cell grafts.

Purpose: To assess the effect of anterior chamber depth on corneal endothelium using specular microscopy following uneventful phacoemulsification among cataract patients with different axial lengths.
Methods: The study was conducted in a quasi-experimental design including 300 eyes of 300 patients with grade three age-related nuclear cataract distributed equally based on their axial length into three equal groups. All eyes had grade three nuclear cataract.

Purpose: To present 4 family members with posterior polymorphous corneal dystrophy (PPCD), nonkeratoconic steep corneas, and myopia caused by a previously unknown genetic alteration in the ZEB1 gene.
Methods: Ophthalmic examinations and corneal curvature analyses were performed for all patients. Whole-exome targeted gene panel sequencing was performed for 1 patient.

Purpose: To evaluate the role of contact lenses (CLs) in visual rehabilitation following keratoplasty.
Methods: Four databases, including PubMed, Scopus, Web of Science, and Embase were systematically searched for studies published between January 2010 and July 2023. Visual outcomes, daily wearing duration, subjective comfort, rate and etiology of CL discontinuation, corneal endothelial cell density, central corneal thickness, and complications were extracted.

Purpose: Congenital hereditary endothelial dystrophy (CHED) impairs the sensitive phase of visual development. We examined results of Descemet stripping automated endothelial keratoplasty (DSAEK) for CHED regarding the critical period for amblyogenic factors.
Methods: Retrospective analysis of 11 eyes of 6 consecutive patients with CHED younger than 8 years treated with DSAEK and a PubMed-based literature search on management and optimal timing of the intervention.

Lipid nanoparticles (LNPs) have shown great potential in the field of gene therapy for retinal diseases. To expand on this application, we investigated LNP-mediated mRNA delivery to the anterior chamber of the eye via the intracameral (IC) route of administration. Here, we show that IC injections of LNPs facilitated protein expression and gene editing in the trabecular meshwork (TM).
