Abstract In ocular surface inflammatory diseases, such as dry eye disease, long-term symptom relief requires targeting the inflammation itself rather than treating only the surface-associated dryness with artificial tears. Therefore, we included an anti-inflammatory agent in an unpreserved liposome-based (LP) formulation used as artificial tears. Our aim was to characterize and study its in vitro and ex vivo cell uptake and functionality. Human corneal epithelial (HCE) cells were used to study...

Abstract Hyaluronan (HA) is frequently incorporated in eye drops to extend the pre-corneal residence time, due to its viscosifying and mucoadhesive properties. Hydrodynamic and rheological evaluations of commercial products are first accomplished revealing molecular weights varying from about 360 to about 1200 kDa and viscosity values in the range 3.7–24.2 mPa s. The latter suggest that most products could be optimized towards resistance to drainage from the ocular surface. Then, a study...
