Abstract: Methods and apparatus for making lens assemblies that can be placed on an eye of a person and that include at least one component are described. Generally, a first lens member (100) and a second lens member (200) are formed. The second lens member (200) is transferred to a compliant stage (210). At least one component is placed in contact with one of the lens members (100, 200). The second lens member (200) is placed in contact with the first lens member (100) such that the compliant stage (210) can provide compression to the first and second lens members (100, 200). The second lens member (200) and the first lens member (100) are coupled together to form a lens assembly (10) with the at least one component located between the two lens members (100, 200).

Abstract: The present disclosure relates to a membrane (140) suitable for forming at least part of a contact lens (500) by bonding to a bulk lens portion (540). The membrane has a central axis (168). The membrane comprises: a first face (142); a second face (144); and a peripheral edge (160). In a cross-sectional plane passing through and parallel to the central axis of the membrane, the thickness (148) of the membrane is at least 10 microns at a distance of 60 microns from the peripheral edge. The present disclosure also relates to a contact lens (500). The contact lens comprises a membrane (140), a bulk lens portion (540), and a bonding interface (510) between at least part of the membrane and at least part of the bulk lens portion. The present disclosure also relates to a method of manufacturing a contact lens.

Abstract: Multilayer contact lenses and methods of making the same are described. A contact lens (100) includes a lens assembly (103). The lens assembly (103) includes a plurality of flexible lens layers. A first layer (101) has a uniform or smooth anterior surface (106), and a second layer (102) has a structured posterior surface that includes one or more recesses (105). The anterior surface (106) of the first layer (101) and the structured posterior surface of the second layer (102) define a first cavity (107) for containing one or more components.

Abstract: A method of producing an ophthalmic lens member is disclosed. The method comprises mounting an ophthalmic lens member blank 16 on a mandrel 1 for machining. The mandrel 1 has a front surface 6 comprising a planar surface region 10, a curved surface region 8 and a tool trench 12 located between the curved surface region 8 and the planar surface region 10. The method comprises mounting the mandrel 1 on a machine tool; and then severing a portion of the ophthalmic lens member blank 16 by passing a cutting tool 70 through the ophthalmic lens member blank 16 until a portion of the cutting tool 70 is received in the tool trench 12. A mandrel 1 suitable for use in the method is also disclosed.

Abstract: A tuneable contact lens (100), wherein the contact lens comprises a central region (108). The central region has a circumferential wall and an anterior surface having an external curvature. The contact lens also comprises an inflatable ring (106) arranged around the circumferential wall of the central region, and at least one fluid reservoir (104) in fluid connection with the inflatable ring. The at least one fluid reservoir comprises a pump. When fluid is pumped from the at least one fluid reservoir to the inflatable ring, the inflatable ring inflates and the external curvature of anterior portion of the central region is changed.
