Abstract:

The aim of the present work was to characterize the surface properties of (poly)methylmethacrylate (PMMA) foils used in ophathalmological applications. Thus, the morphology, chemical composition and surface energy of these PMMA foils are analyzed, by specific measurements, at the interface with different test liquids of interest in ophthalmology, i.e. distilled H2O, physiological serum and ophthalmic solution of ReNu Multiplus, used for contact lens cleaning, hydration and disinfection. Also, a solution of Nostamine, known as a drug used in eye irritation and conjunctival inflammation, was tested.
