SCLERAL FIXATION BAG
A method is described for introducing a scleral fixation bag into an eye. The scleral fixation bag includes haptics that extend therefrom. The method includes inserting and affixing the haptics into sclerotomies formed in the eye; the haptics affix the scleral fixation bag without a need for natural capsular bag support. The haptics of the scleral fixation bag include a slender loop element and a distal hook portion that extends from a distal end of the slender loop element. The distal hook portion has an anterior edge tilted towards the central anterior-posterior axis of the scleral fixation bag.
1 . A method comprising:
introducing a scleral fixation bag into an eye, said scleral fixation bag comprising haptics that extend therefrom; and
inserting and affixing said haptics into sclerotomies formed in the eye, wherein said haptics affix said scleral fixation bag without a need for natural capsular bag support.
2 . The method according to claim 1 , wherein no capsular bag is present.
3 . The method according to claim 1 , further comprising mounting an intraocular device into a channel formed in said scleral fixation bag.
4 . An intraocular device comprising:
a scleral fixation bag comprising haptics that extend therefrom, each of said haptics comprising a slender loop element with a proximal end attached to said scleral fixation bag, 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 scleral fixation bag; 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 scleral fixation bag.
5 . The intraocular device according to claim 4 , wherein said distal hook portion comprises a posterior edge tilted away from the central anterior-posterior axis of said scleral fixation bag.
6 . The intraocular device according to claim 4 , 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.
7 . The intraocular device according to claim 4 , wherein said distal hook portion is flat.
8 . The intraocular device according to claim 4 , wherein the thickness of said slender loop elements is less than the width.
9 . The intraocular device according to claim 4 , wherein said distal hook portion is formed with a central through hole.
10 . The intraocular device according to claim 4 , wherein said distal hook portion and said slender loop element have different rigidity.
11 . The intraocular device according to claim 4 , wherein an anterior-most surface of said distal hook portion is not posterior to an anterior-most surface of said intraocular device.
12 . The intraocular device according to claim 4 , wherein said scleral fixation bag comprises a channel for receiving therein a different intraocular device.
13 . The intraocular device according to claim 4 , wherein a posterior platform is attached to said scleral fixation bag.
14 . The intraocular device according to claim 13 , wherein said posterior platform is formed with an annular groove.
15 . The intraocular device according to claim 4 , wherein said posterior platform has optical power.
16 . The method according to claim 4 , further comprising mounting another intraocular device in the posterior chamber anterior to the intraocular device mounted in said scleral fixation bag.
