In Vivo Evaluation of Injected and Bioprinted Hyaluronic Acid‐Based Bioink in Corneal Stromal Pocket

Macromolecular Bioscience, Volume 26, Issue 1, January 2026.
Hyaluronic acid‐based bioinks support the viability of cells and keratocyte‐like characteristics. They integrate with host cornea stroma and adapt to irregular pockets through stable in situ gelation. The bioinks remain optically transparent, promote tissue remodeling, and reduce haze and inflammation.
