Extracellular vesicles (EVs) are small membrane-bound particles that play a vital role in intercellular communication by facilitating the transfer of molecular cargo. In this review, we provide an overview of EV biology in corneal diseases, along with current approaches to therapeutic uses of EVs. Since EVs generally retain surface markers indicative of their cell of origin, they possess a degree of tissue specificity, which benefits drug delivery systems and highlights their potential as biomarkers to study disease processes. Further advances in technology and methodology will accelerate our understanding of EVs and help guide the field towards improved diagnostic techniques and therapeutic targets. We summarize EVs and their potential impact in medicine with a discussion of the limitations that remain in current approaches, as well as areas to focus on for future growth.
