Contact and intraocular lenses comprising an adjustable focus length

The invention relates to a lens (1) for vision correction, wherein the lens (1) is configured to be placed directly on the surface of an eye (2) of a person or to be implanted into an eye (2) of a person, and wherein the lens (1) further comprises: a transparent base element (10) having a back side (12) and a front side (11) facing away from the back side (12), a transparent and elastically expandable membrane (20) connected to said base element (10), wherein said membrane (20) comprises a back side (22) that faces said front side (11) of the base element (10), a ring member (30) connected to said back side (22) of the membrane (20) so that the ring member (30) defines a curvature-adjustable area (23) of the membrane (20), and wherein the lens (1) comprises a lens volume (41) adjacent said curvature-adjustable area (23) of the membrane (20), which lens volume (41) is delimited by the ring member (30), and wherein the lens (1) comprises a reservoir volume (42) adjacent a boundary area (24) of said membrane (20), wherein said two volumes (41, 42) are filled with a transparent liquid (50), and wherein said volumes (41, 42) are fluidly connected or fluidly connectable to each other such that, when the reservoir volume (42) is compressed, liquid (50) residing in the reservoir volume (42) is pressed into the lens volume (41) such that the curvature of said curvature-adjustable area (23) of the membrane (22) increases and the focal length of the lens (1) decreases. Further, the invention relates to a method for manufacturing a contact lens according to the invention.. ... Optotune Ag

Tunable lens device

The present invention relates to a lens device (1), comprising: a transparent and elastically expandable membrane (10), an optical element (20) opposing the membrane (10), a wall member (300), wherein the optical element (10) and the membrane (10) are connected to the wall member (300) such that a volume (v) is formed, a fluid (f) residing in said volume (v), and a lens shaping member (11) attached to the membrane (10). According to the invention the lens device (1) comprises an actuator means (40) that is designed to move the optical element (20) in an axial direction (a) with respect to the lens shaping member (11) so as to adjust the pressure of the fluid (f) residing inside the volume (v) and therewith a curvature of said membrane (10), wherein said axial direction (a) is oriented perpendicular to a plane spanned by the lens shaping member (11), and wherein said actuator means (40) is designed to tilt the optical element (20) with respect to said plane, particularly so as to form the volume into a prism for deflecting light passing the volume. ... Optotune Ag

Variable focus lens

The invention relates to a variable focus lens comprising an elastically deformable optical element (7) and a circumferential mechanism (10, 1, 5, 2, 3, 8, 21) to transfer a rotational movement to an axial movement, wherein by using a ball bearing system (9, 11, 12, 13, 15, 16, 17) the mechanism is optimized in a manner to reduce mechanical friction, friction variation and to improve force-direction dependent positioning insensitivity.. . ... Optotune Ag

Optical device for enhancing resolution of an image

The invention relates to an optical device (1) for enhancing the resolution of an image, comprising: a transparent plate member (10) configured for refracting a light beam (20) passing through the plate member (10), which light beam (20) projects an image comprised of rows and columns of pixels (40), a carrier (50) to which said transparent plate member (10) is rigidly mounted, wherein the carrier (50) is configured to be tilted between a first and a second position about a first axis (a), such that the plate member (10) is tilted between the first and the second position about the first axis (a), whereby said projected image (30) is shifted by a fraction (Δp) of a pixel, particularly by a half of a pixel, along a first direction (x), and an actuator means (60) that is configured to tilt the carrier (50) and therewith the plate member (10) between the first and the second position about the first axis (a).. . ... Optotune Ag

Optical device, particularly for tuning the focal length of a lens of the device by means of optical feedback

The invention relates to an optical device, comprising: a lens (10) having an adjustable focal length (f). According to the invention, a light source which is configured to emit light (51) that is affected by said lens (10) and impinges on at least a first photosensitive element (30), which is designed to generate a first output signal (o1) corresponding to the intensity of light impinging on it, wherein the first photosensitive element (30) is configured to measure only a portion of the intensity distribution of said emitted light (51), and wherein the light source (50), the lens (10) and the first photosensitive element (30) are configured such that a change of the focal length (f) of said lens (10) changes the intensity distribution of the emitted light (51) that impinges on the first photosensitive element (30), so that each focal length (f) of the lens (10) is associated to a specific first output signal (o1) generated by the first photosensitive. ...
