摘要： The present invention discloses a contact lens mould for producing a contact lens. The mould comprises a first mould half (10) having a convex moulding surface (36m) of predetermined curvature, and a second mould half (12) having a concave moulding surface (26f) of predetermined curvature. The first mould half (10) is provided with an annular abutment surface (38m) which circumferentially surrounds and is contiguous with the convex moulding surface (36m), and the second mould half (12) is provided with a flexible annular lip (28f) which circumferentially surrounds the concave moulding surface (26f). In use, when the mould halves (10, 12) are brought together, the annular lip (28f) forms a continuous line contact with the abutment surface (38m) whereby a mould cavity (40) is defined between the moulding surfaces (26f, 36m), a radially inner surface (42f) of the annular lip (28f) and at least part of the abutment surface (38m), and an angle (α) of less than 180° is defined between the abutment surface (38m) and the convex moulding surface (36m) at their intersection and an included angle (θ) of less than 90° is defined between the abutment surface (38m) and the radially inner surface (42f) of the lip (28f). As the mould halves (10, 12) are brought closer together during polymerisation, the lip (28f) flexes radially outwardly.

摘要： A casting mold half (5, 5a) for producing contact lenses comprises a mount (50) and an insert (51, 51a), which is arranged at one end of the mount (50) and can be connected to the mount (50) and which has a shaping surface (510) for the shaping of the front or rear surface of the contact lens to be produced. The insert (51, 51a) consists in the region of the shaping surface (510) of a material which is permeable to the energy crosslinking the starting material of the contact lens. Finally, a mask made of a material impermeable to the energy crosslinking the starting material is provided for spatially delimiting this energy. The mask comprises a separate surround (512) made of a material impermeable to the energy crosslinking the starting material of the contact lens, which surrounds the edge region of the shaping surface (510) of the insert (51, 51a).

摘要： The invention provides a disposable plastic mold assembly (10) for an intraocular lens or the optic body thereof, which is inexpensive, less labor intensive than prior art intraocular lens molding techniques, and produces an intraocular lens having smooth, polished edges which require little or no post-mold finishing work. Numerous innovative features of the invention include an edge design which assures a seal between the male (12) and female (14) molds to thereby minimize flash during the cast molding operation, and the provision of a means for pre-aligning the male and female molds during assembly, consisting of an interference fitting relationship between the male and female molds. An additional feature is a means for maintaining contact between the male and female molds during casting, which particularly involves the provision of a negative draft angle on the inner surface of the female mold's outer wall, or, alternatively, texturing which is applied to that inner surface so that it engages the outer edge at the top of the male mold during assembly. Yet another important feature of the invention is a means for achieving axial and rotational orientation to produce lens edge geometries without unwanted steps on the lens edge. The alignment is achieved with interlocking steps (34, 36, 38) on the male and female molds. The interlocking elements may be pins or annular elements.
摘要翻译：本发明提供了一种用于眼内透镜或其光学本体的一次性塑料模具组件（10），其廉价，比现有技术的眼内透镜模制技术更少的劳动密集度，并且产生具有光滑抛光边缘的眼内透镜，其需要很少或无后模整理工作。本发明的许多创新特征包括边缘设计，其确保在阳模（12）和阴模（14）之间的密封，从而在浇铸模制操作期间最小化闪光，并且提供用于预对准男性和女性组装过程中的模具由阳模和阴模之间的干涉配合关系组成。额外的特征是用于在铸造期间保持阳模和阴模之间的接触的手段，其特别地涉及在阴模的外壁的内表面上提供负牵伸角，或者替代地，施加到内模表面，使得其在组装期间与阳模的顶部处的外边缘接合。本发明的另一个重要特征是用于实现轴向和旋转取向以产生透镜边缘几何形状而在镜片边缘上没有不必要的步骤的手段。在阳模和阴模上具有互锁台阶（34,36,38）来实现对准。互锁元件可以是销或环形元件。

摘要： Process and apparatus for molding the front and rear surfaces of a contact lens in one step is disclosed. Two mold halves (110, 112) matable to form a contact-lens-shapes cavity and a cavity (119) for excess lens forming material surrounding the cavity are provided. The improvement comprises providing the cavity with at least two openings (121, 132, 133) and producing differential gas pressure across the openings to remove excess lens forming material.

摘要： Spherical hydrophilic contact lenses having a characteristic tricurve configuration designed to correct myopia (nearsightedness). The center zone (A1) of the lens is substantially thinner than the periphery (A3) allowing enhanced oxygen transmission and comfortable, increased wearing times while the thicker mid-periphery (A2) imparts necessary integrity and handling characteristics for convenience in manual manipulation. Lenses are molded or cast directly in the desired tricurve configuration using specially designed replica molds made from metal master molds.
