    • Systems and methods for producing silicone hydrogel contact lenses are described. Certain of the present systems include a contact lens mold forming station (210), a station (212) for filling a contact lens mold section (1010) with a lens precursor composition (1118) and for placing a second mold section (1010) on the filled mold section (1010) to form a contact lens mold assembly, a curing station (214) for forming a contact lens (1413), a mold assembly separation station (216), and an extraction/hydration station (218). Certain of the present methods include forming a plurality of mold sections (1010), placing a lens precursor composition (1118) on a surface of a first mold section (1010), placing a second mold section (1010) on the first mold section (1010), polymerizing the lens precursor composition (1118), separating the first and second mold sections (1010), removing the silicone hydrogel contact lens (1413) from one of the mold sections (1010), extracting extractable components from the contact lens (1413), and hydrating the contact lens (1413).
    • 描述了制备硅酮水凝胶隐形眼镜的系统和方法。 本发明的一些系统包括隐形眼镜成型工位(210),用于用透镜前体组合物(1118)填充隐形眼镜模具部分(1010)并将第二模具部分(1010)放置在其上的工位(212) 填充的模具部分(1010)以形成隐形眼镜模具组件,用于形成隐形眼镜(1413)的固化站(214),模具组件分离站(216)和提取/水化站(218)。 本发明的某些方法包括形成多个模具部分(1010),将透镜前体组合物(1118)放置在第一模具部分(1010)的表面上,将第二模具部分(1010)放置在第一模具部分 1010),聚合透镜前体组合物(1118),分离第一和第二模具部分(1010),从模具部分(1010)之一去除硅氧水凝胶隐形眼镜(1413),从隐形眼镜中提取可提取组分 1413),并且使隐形眼镜(1413)保湿。

    • A blister package (10) housing a contact lens (113) is described. The package (10) generally includes a base member (12) including a cavity (18) having a bottom surface (38), for containing a contact lens (10) immersed in a liquid medium. The base member can include a grip region (22) including a curved top surface (22a) shaped to accommodate a thumb and a curved bottom surface (22b) shaped to accommodate an inner curve of a forefinger. Silicone hydrogel contact lenses (10) located in the liquid medium have a reduced tendency to stick to the bottom surface (38) of the cavity (18) without requiring a surfactant and/or a surface modification of the bottom surface (38).
    • 描述了容纳隐形眼镜(113)的泡罩包装(10)。 包装(10)通常包括具有底部表面(38)的空腔(18)的基底构件(12),用于容纳浸入液体介质中的隐形眼镜(10)。 基部构件可以包括夹持区域(22),该夹持区域(22)包括成形为容纳拇指的弯曲顶部表面(22a)和形状适合食指的内部曲线的弯曲底部表面(22b)。 位于液体介质中的硅氧水凝胶隐形眼镜(10)具有降低空腔(18)底面(38)的倾向,而不需要表面活性剂和/或底表面(38)的表面改性。
