HAPTICS FOR INTRAOCULAR DEVICES
An intraocular device having anterior and posterior faces, haptics extending from the intraocular device, each of the haptics including a slender loop element with a proximal end attached to the intraocular device, the slender loop element having a length, width and thickness, the length following a curved path and the width being generally parallel to a central anterior-posterior axis of the intraocular device, and a distal hook portion extending from a distal end of the slender loop element, the distal hook portion including an anterior edge tilted towards the central anterior-posterior axis of the intraocular device.
1 . An assembly comprising:
an intraocular device having anterior and posterior faces;
haptics extending from said intraocular device, each of said haptics comprising a slender loop element with a proximal end attached to said intraocular device, said slender loop element having a length, width and thickness, the length following a curved path and the width being generally parallel to a central anterior-posterior axis of said intraocular device; and
a distal hook portion extending from a distal end of said slender loop element, said distal hook portion comprising an anterior edge tilted towards the central anterior-posterior axis of said intraocular device.
2 . The assembly according to claim 1 , wherein said distal hook portion comprises a posterior edge tilted away from the central anterior-posterior axis of said intraocular device.
3 . The assembly according to claim 1 , wherein said distal hook portion is rounded at its distal tip and tapers to be thinner from where it extends from said slender loop element.
4 . The assembly according to claim 1 , wherein said distal hook portion is flat.
5 . The assembly according to claim 1 , wherein said distal hook portion is thinner than said slender loop element.
6 . The assembly according to claim 1 , wherein the thickness of said slender loop elements is less than the width.
7 . The assembly according to claim 1 , wherein said distal hook portion is formed with a central through hole.
8 . The assembly according to claim 1 , wherein the proximal end of said slender loop element is generally tangential to an outer periphery of said intraocular device.
9 . The assembly according to claim 1 , wherein said distal hook portion and said slender loop element have different rigidity.
10 . The assembly according to claim 1 , wherein said slender loop element and said intraocular device have different rigidity.
11 . The assembly according to claim 1 , wherein an anterior-most surface of said distal hook portion is not posterior to an anterior-most surface of said intraocular device.
12 . The assembly according to claim 1 , wherein an anterior-most surface of said slender loop element is not posterior to an anterior-most surface of said intraocular device.
13 . The assembly according to claim 1 , wherein said slender loop element is a slender wire and said distal hook portion is a rounded eyelet formed from an end of said slender wire.
14 . The assembly according to claim 1 , wherein said intraocular device comprises an IOL.
15 . The assembly according to claim 1 , wherein said intraocular device comprises an implantable miniature telescope.
