Title:
CONTACT AND INTRAOCULAR LENSES COMPRISING AN ADJUSTABLE FOCUS LENGTH
Document Type and Number:
WIPO Patent Application WO/2016/174181
Kind Code:
A3
Abstract:
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.
