Process for treating hydrophobic polymer surfaces to form hydroxyl moieties thereon comprises ozonating the surface of said hydrophobic polymer to form hydroperoxy groups thereon, and then irradiating said ozonated surface with ultraviolet light or exposing to heat to convert the hydroperoxy groups to hydroxyl moieties in the presence of a hydrogen donor. Such hydroxylated surfaces possess hydrophilic properties and can undergo the chemical reactions characteristic for hydroxyl groups. Polymers so modified are useful in biomedical devices, semipermeable membranes, films, fibers and especially contact lenses.
