摘要： Biomedical devices, such as ophthalmic lenses, and methods of making such devices having a surface coating including at least one polyionic layer. A preferred method involves spray coating a polycationic material onto a core lens, rinsing and drying the lens, followed by spray coating a polyanionic material, rinsing and drying. The coating process may be applied a plurality of times to achieve a multi-layer coating on the lens surface. A particularly preferred embodiment is a contact lens comprising a highly oxygen permeable hydrophobic core coated with a 5 to 20 bilayers of hydrophilic polyionic materials.

摘要： A method of incorporating radiation-absorbing agents (i.e., dyes) into polymeric materials. A preferred method involves crosslinking or polymerizing a polymerizable or crosslinkable material in the presence of a polymeric dye. A preferred product is a tinted contact lens comprising poly(vinyl alcohol). The methods offer advantages in reduced fabrication cycles, reduced extractables, elimination of post-polymerization activation steps, elimination of post-polymerization extraction steps and reduced scrap and costs associated with lens handling.

摘要： The invention relates to a process for the manufacture of tinted ophthalmic moldings comprising the steps of(a) providing a water soluble polymer precursor having crosslinkable or polymerizable groups;(b) providing a pigment dispersion comprising an inorganic or organic pigment and a dispersing agent;(c) mixing the metal phthalocyanine dye or pigment with the polymer precursor to form a tinted prepolymerization mixture,(d) dispensing the tinted prepolymerization mixture into a mold,(e) applying radiation to the tinted prepolymerization mixture in the mold, thereby crosslinking or polymerizing the polymer precursor and entrapping the dye or pigment within the polymeric network of the resultant ophthalmic molding, and(f) opening the mold so that the ophthalmic molding can be removed from the mold.According to the process, tinted ophthalmic moldings, particularly full-body tinted soft contact lenses having improved properties, are prepared with an improved efficiency.
