具有可调焦距的接触镜片和眼内镜片
摘要：
本发明涉及一种用于视力矫正的镜片(1)，其中镜片(1)被配置为直接放置在人的眼睛(2)的表面上或者植入到人的眼睛(2)中，并且其中镜片(1)还包括：透明的基部元件(10)，该基部元件具有后侧(12)和背离后侧(12)的前侧(11)；透明且弹性可膨胀的膜(20)，该膜连接至所述基部元件(10)，其中所述膜(20)包括面向基部元件(10)的所述前侧(11)的后侧(22)；环构件(30)，该环构件连接至膜(20)的所述后侧(22)，使得环构件(30)限定膜(20)的曲率可调区域(23)；并且其中镜片(1)包括邻近膜(20)的所述曲率可调区域(23)的镜片块体(41)，镜片块体(41)由环构件(30)界定，并且其中镜片(1)包括邻近所述膜(20)的边界区域(24)的储存器块体(42)，其中所述两个块体(41、42)填充有透明液体(50)，以及其中所述块体(41、42)彼此流体地连接或能流体地连接，使得当储存器块体(42)被压缩时，驻留在储存器块体(42)中的液体(50)被压入镜片块体(41)中，使得膜(22)的所述曲率可调区域(23)的曲率增加，并且镜片(1)的焦距减小。此外，本发明涉及一种用于制造根据本发明的接触镜片的方法。
摘要（英）：

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 tosaid 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 saidcurvature-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.
