When trehalose is used in the eye, it allows the cell membranes to be stabilized. It protects cells from breaking down, maintains proteins, and retains water, acting as an osmoprotectant. In the conjunctiva and corneal epithelial cells specifically, trehalose retains water and suppresses apoptosis. The cells are actually able to be repaired.
Watch below as Dr Clara Chan discusses the role Trehalose has on the Ocular Surface.
