Abstract
Modular IOL systems including a base and a lens, wherein the lens includes fixed and actuatable tabs for connection to the base. The modular IOL allows for the lens to be adjusted or exchanged while leaving the base in place, either intra-operatively or post-operatively. Drug delivery capabilities and/or sensing capabilities may be incorporated into the base. Injector devices may be used to facilitate placement of the base and the lens sequentially or simultaneously into the eye.
Claims22
A method of implanting an intra-ocular lens (IOL) in an eye having a capsular bag with an internal volume, the method comprising:
- positioning the IOL in the capsular bag, the IOL including:
- an optic having a central visual axis and a central thickness along the central visual axis, and
- an annular ring surrounding the optic, the annular ring including:
- a periphery,
- a first rim surrounding the optic, and
- a second rim surrounding the optic and disposed opposite the first rim, the first rim and the second rim flaring outwardly toward the central visual axis from the periphery, the first rim and the second rim establishing an anterior-posterior thickness of the annular ring that is greater than the central thickness of the optic,
- wherein positioning the IOL in the capsular bag includes orienting the first rim anteriorly and the second rim posteriorly in the eye;
- and
- filling between about 25% to about 50% of the volume of the capsular bag with the IOL.
A method of implanting an intra-ocular lens (IOL) in an eye having a capsular bag with an internal volume, the method comprising:
- positioning the IOL in the capsular bag, the IOL including:
- an optic having a central visual axis and a central thickness along the central visual axis, and
- an annular ring surrounding the optic, the annular ring including:
- a periphery,
- a first rim surrounding the optic, and
- a second rim surrounding the optic and disposed opposite the first rim, the first rim and the second rim flaring outwardly toward the central visual axis from the periphery, the first rim and the second rim establishing an anterior-posterior thickness of the annular ring that is greater than the central thickness of the optic,
- wherein positioning the IOL in the capsular bag includes orienting the first rim anteriorly and the second rim posteriorly in the eye, and
- wherein positioning the IOL in the capsular bag includes assembling the optic to the annular ring.
A method of implanting an intra-ocular lens (IOL) in an eye having a capsular bag with an internal volume, the method comprising:
- positioning the IOL in the capsular bag, the IOL including:
- an optic having a central visual axis and a central thickness along the central visual axis, and
- an annular ring surrounding the optic, the annular ring including:
- a central longitudinal axis,
- an first angled rim surrounding the optic,
- a second angled rim surrounding the optic, the first angled rim and the second angled rim establishing a thickness of the annular ring, the annular ring having a first anterior-posterior thickness at a first distance from the central longitudinal axis, and the annular ring having a second anterior-posterior thickness at a second distance from the central longitudinal axis, the second distance being greater than the first distance, the first anterior-posterior thickness being greater than the second anterior-posterior thickness, and the first anterior-posterior thickness being greater than the central thickness of the optic;
- and
- filling between about 25% and about 50% of a volume of the capsular bag with the IOL.
