Purpose of review With limited access of more than half the world's population to corneal transplantation, regenerative medicine may represent a promising alternative. This review explores the main advancements achieved in cell-based therapies for corneal epithelium, stroma, and endothelium during 2021–2022. Recent findings Multiple surgical techniques have been developed for epithelial limbal stem cell replacement. Recent studies aimed to gain greater understanding and characterization of these techniques. Though no clear superiority could be demonstrated, simple limbal epithelial transplantation seems to have the most clinical and cost effectiveness. For stromal disease, autologous adipose-derived stem cells have shown favorable results. For endothelial dysfunction, the validity of intracameral cultivated allogeneic endothelial cell injection and Descemetorrhexis without endothelial keratoplasty, as well as the benefits of adjunctive rho-associated kinase inhibitors, were emphasized. Summary A plethora of innovative cell-based regenerative therapies for corneal diseases have been developed in past years. While recent literature solidifies our knowledge, most studies are still in preliminary or preclinical stages. Though showing great promise, these approaches will require larger studies with better-defined endpoints to establish their benefits over currently available treatments.
