Abstract
Intraocular lenses for implanting within natural capsular bags of human eyes have features on distal end portions to prevent movement or sliding thereof relative to fibrosis pockets or tunnels defined about proximally adjacent haptic portions to fixate haptics against dislocation.
Claims15
An intraocular lens for implanting within a natural capsular bag of a human eye, said lens implant comprising:
- a lens body having anterior and posterior sides and including an optic and two or more plate haptics spaced about said optic, said haptics having inner ends adjacent said optic and outer ends extending from said optic;
- a plurality of protuberances extending outwardly from at least one of the anterior and/or posterior sides of one or more of said haptics to fixate said haptic in a natural capsular bag of an eye;
- and
- at least one of said haptics has a plurality of openings formed therethrough to allow fibrosis of an anterior capsule remnant to a posterior capsule remnant through said haptic outer end opening following implantation of said lens into a natural capsular bag of an eye.
An intraocular lens for implanting within a natural capsular bag of a human eye, said lens implant comprising:
- a lens body having anterior and posterior sides and including an optic and haptics spaced about said optic, said haptics having inner ends adjacent said optic and outer ends extending from said optic;
- said haptics comprise a plurality of four plate haptics, wherein said haptic outer ends have a width greater than the width of said haptic inner ends;
- and
- at least one of said haptics has a plurality of protuberances extending outwardly from at least one of the anterior and/or posterior sides of said at least one haptic to fixate said haptic in a natural capsular bag of an eye.
An intraocular lens for implanting within a natural capsular bag of a human eye, said lens implant comprising,
- a lens body having anterior and posterior sides and including an optic and haptics spaced about said optic, said haptics having inner ends adjacent said optic and outer ends extending from said optic;
- said haptics comprise a plurality of four plate haptics, wherein said haptic outer ends have a width greater than the width of said haptic inner ends;
- and
- at least one of said haptic outer ends has one or more flexible loops having an inner end adjacent said haptic outer end and an outer end extending outwardly from said haptic outer end.
An intraocular lens for implanting within a natural capsular bag of a human eye, said lens implant comprising:
- a lens body having anterior and posterior sides and including an optic and a disk haptic extending about said optic, said disk haptic has an inner portion adjacent said optic and an outer portion extending from said optic;
- and
- a plurality of loops having an inner end joined to said disk and an outer end extending outwardly from said disk outer portion, wherein said loops are adapted to fixate said lens in a natural capsular bag of an eye following implantation.
An intraocular lens for implanting within a natural capsular bag of a human eye, said lens implant comprising:
- a lens body having anterior and posterior sides and including an optic and a disk haptic extending about said optic, said disk haptic has an inner portion adjacent said optic and an outer portion extending from said optic;
- a plurality of protuberances extending outwardly from at least one of the anterior and/or posterior sides of said disk haptic to fixate said disk haptic in a natural capsular bag of an eye;
- and
- said disk haptic has a plurality of openings formed therethrough to permit fibrosis of an anterior capsule remnant to a posterior capsule remnant through said disk haptic opening following implantation of said lens into a natural capsular bag of an eye.
An intraocular lens for implanting within a natural capsular bag of a human eye, said lens implant comprising:
- a lens body having anterior and posterior sides and including an optic and a disk haptic extending about said optic, said disk haptic has an inner portion adjacent said optic and an outer portion extending from said optic;
- and
- a plurality of protuberances extending outwardly from at least one of the anterior and/or posterior sides of said disk haptic to fixate said disk haptic in a natural capsular bag of an eye.
An intraocular lens for implanting within a natural capsular bag of a human eye, said lens implant comprising:
- a lens body having anterior and posterior sides and including an optic and two half disk haptics extending from said optic, said half disk haptics have inner portions adjacent said optic and outer portions extending from said optic;
- and
- one or more loops having an inner end joined to said half disk and an outer end extending outwardly from said half disk outer portion, wherein said loops are adapted to fixate said lens in a natural capsular bag of an eye following implantation.
An intraocular lens for implanting within a natural capsular bag of a human eye, said lens implant comprising:
- a lens body having anterior and posterior sides and including an optic and two or more haptics spaced about said optic, said haptics having inner ends adjacent said optic and outer ends extending from said optic;
- and
- at least one of said haptics has a plurality of protuberances extending outwardly from at least one of the anterior and/or posterior sides of said at least one haptic to fixate said haptic in a natural capsular bag of an eye.
