Evaluating the efficacy of stem cells in treating severe dry eye disease.

Dry eye disease (DED) is a multifactorial disorder that disturbs ocular surface equilibrium, considerably diminishing quality of life. Present therapies only offer symptomatic alleviation. Stem cell treatment, especially mesenchymal stem cells (MSCs), has surfaced as a viable approach for tissue regeneration and immunological regulation in DED. Preclinical and early clinical investigations indicate that MSCs can improve lacrimal gland functionality, diminish inflammation, and facilitate corneal regeneration. Nonetheless, obstacles persist in enhancing MSC viability, determining the optimal MSC source, and guaranteeing sustained therapeutic effectiveness. Additional extensive randomized clinical trials are required to confirm the efficacy of MSC-based therapies for severe DED.
