Allogeneic ocular surface stem cell transplantation (OSST) is an established therapeutic approach for limbal stem cell deficiency, utilizing techniques such as keratolimbal allograft (KLAL), living-related conjunctival limbal allograft (lr-CLAL), allogeneic cultivated limbal epithelial transplantation (allo-CLET), and allogeneic simple limbal epithelial transplantation (allo-SLET). This review synthesizes evidence from 35 studies encompassing 1, 268 eyes with at least 24 months of follow-up to evaluate intermediate- and long-term outcomes. Overall, OSST is associated with improvement in visual acuity and restoration of ocular surface stability, although success rates vary widely by technique, ranging from 13% to 87%. Outcomes appear to be influenced by the …

Penetrating keratoplasty has long been the standard treatment for many corneal pathologies, but interest has grown in less invasive, tissue-sparing alternatives. Bowman’s layer (BL) and Descemet’s membrane (DM) transplantation are two anterior approaches that use isolated acellular corneal layers to restore structural support and promote epithelial healing, while avoiding many of the limitations of full-thickness grafting. Although both techniques have been described for ectatic disorders, their theoretically low immunogenicity, minimal long-term steroid requirements, and capacity to support reepithelialization make them appropriate options for a range of nonectatic indications. This narrative review describes the application of BL (11 studies) and DM …
