    • The invention is related to a method for producing soft contact lenses comprises a silicone hydrogel lens body and a composite coating thereon. The composite coating comprises: a plasma base coating which is chemically-attached directly onto the surface of the silicone hydrogel contact lens and functions as a fail-proof measure for ensuring the hydrophobic silicone hydrogel lens material to be shielded from any exposure to ocular environments even after at least 30 days of daily uses including daily waring and daily cleaning/disinfecting; and a relatively-durable lubricious hydrogel top coating for ensuring wearing comfort. A method of the invention comprises forming a plasma-reactive hydrophilic polymer hybrid base coating having reactive functional groups on a silicone hydrogel contact lens and heating the silicone hydrogel contact lens with the hybrid base coating in an aqueous solution of a water-soluble and thermally crosslinkable hydrophilic polymeric material to form a stable lubricious hydrogel coating thereon. This method has a minimized adverse impact on the mechanical properties of silicone hydrogel lens body.
    • 本发明涉及一种用于制造软性隐形眼镜的方法,所述软性隐形眼镜包含硅酮水凝胶镜片主体及其上的复合涂层。 该复合涂层包括:等离子体基底涂层,其直接化学连接到硅酮水凝胶隐形眼镜的表面上,并且起到防止措施的作用,以确保疏水性硅酮水凝胶镜片材料被防止暴露于任何眼睛环境中 经过至少30天的日常使用后,包括日常使用和日常清洁/消毒; 和一个相对耐用的润滑水凝胶顶部涂层,以确保穿着舒适。 本发明的方法包括在硅酮水凝胶隐形眼镜上形成具有反应性官能团的等离子体反应性亲水聚合物混合底涂层,并将该硅酮水凝胶隐形眼镜与混合底涂层在水溶性且可热交联的水溶液中加热 亲水性聚合物材料以在其上形成稳定的润滑水凝胶涂层。 该方法对硅酮水凝胶镜片主体的机械性能具有最小的不利影响。

    • The invention is generally related to soft contact lenses which comprise a non-silicone hydrogel lens body and a hydrogel coating thereon. The non-silicone hydrogel lens body is composed of a hydrogel material which is free of silicone and comprises at least 50% by mole of repeating units of at least one hydroxyl-containing vinylic monomer. The hydrogel coating comprises a first polymeric material having first reactive functional groups and a hydrogel layer derived from a second polymeric material having second reactive functional groups, and the hydrogel layer is covalently attached onto the anchor layer through linkages each formed between one first reactive functional group and one second reactive functional group. The soft contact lens has a surface lubricity better than the lubricity of the non-silicone hydrogel lens body and has a friction rating of about 2 or lower after 7 cycles of manual rubbing, a water content of from about 10% to about 85% by weight and an elastic modulus of from about 0.2 MPa to about 1.5 MPa when being fully hydrated at room temperature.
