Intraocular lens (IOL) with multi optics assembly
View Patent ↗The various embodiments of the present invention provide a multi-optics intraocular lens (IOL) scaffold assembly for incorporation into a capsular bag of an eye of a subject, provided with a ring platform and a protective umbrella. Several anterior and posterior ribs are hinged to the ring platform to support a posterior lens and an anterior lens. The dynamic spring elastic junctions are provided between the anterior and posterior ribs. The pendulum IOL assembly of the multi-optics intraocular lens (IOL) scaffold assembly enables a near vision of the objects using an optical system designed for a distance focusing in normal gaze. The pendulum IOL assembly has a posterior lens fixed to an equatorial ring platform and a secondary hanging lens provided with a weight at the lower end to act like a pendulum which swings with the posture of the eye.
1. A multi-optics intraocular lens (IOL) scaffold assembly for incorporation into a capsular bag of an eye of a subject, comprising:
an anterior ring with an anterior optical lens configured to be disposed in the anterior region of the capsular bag;
a posterior optical lens configured to be disposed in the posterior region of the capsular bag;
a plurality of movable anterior and posterior ribs configured to extend radially from the anterior ring and the posterior optical lens, and anchored to a ring platform, through a plurality of hinges;
a hinge protective umbrella configured to enclose the ring platform; and
a plurality of dynamic elastic spring junctions operably connected to the anterior and posterior ribs.
2. The IOL scaffold assembly according to claim 1 , wherein the anterior ribs and posterior ribs are anchored to the ring platform and configured to move the anterior and posterior ribs farther from and closer to each other.
3. The IOL scaffold assembly according to claim 1 , wherein the anterior and posterior ribs are convex with intervening spaces.
4. The IOL scaffold assembly according to claim 1 , wherein the anterior and posterior ribs are covered with webs that are medically coated and are made of transparent surgical grade material.
5. The IOL scaffold assembly according to claim 1 , wherein the anterior ribs and the posterior ribs are pivoted to the plurality of hinges for swiveling action.
6. The IOL scaffold assembly according to claim 1 , wherein the anterior lens is a single intraocular lens, bi-focal intraocular lens or a multi-focal intraocular lens.
7. The IOL scaffold assembly according to claim 1 , wherein the ring platform is disposed at the equatorial region of the capsular bag to support the anterior and posterior ribs.
8. The IOL scaffold assembly according to claim 1 , wherein the plurality of dynamic elastic spring junctions comprises:
a rod;
an anterior rod; and
a posterior rod;
wherein the anterior rod is connected to an anterior rib and the posterior rod is connected to a posterior rib and wherein the anterior rod and the posterior rod are telescopically coupled to each other.
9. The IOL scaffold assembly according claim 8 , wherein a spring is disposed internally to connect the anterior and posterior rods, wherein said spring is configured to push the posterior rods and the anterior rods away from each other.
10. The IOL scaffold assembly according to claim 8 , wherein a plurality of elastic bands are disposed externally to connect the anterior and posterior rods, wherein said elastic bands are configured to draw the anterior rods and the posterior rods close to each other.
11. An multi-focus intraocular lens (IOL) scaffold assembly for incorporation into a capsular bag of an eye of a subject:
(a) an anterior ring with an anterior optical lens configured to be disposed in the anterior region of the capsular bag;
(b) a posterior optical lens configured to be disposed in the posterior region of the capsular bag;
(c) a plurality of movable anterior and posterior ribs configured to extend radially from the anterior ring and the posterior optical lens, and anchored to a ring platform;
(d) a suspension platform connected to the ring platform; and
(e) a movable and weighted secondary lens suspended from the suspension platform and disposed in between the posterior lens and the anterior ring.
12. The IOL scaffold assembly according to claim 11 , wherein the secondary lens is suspended freely with a plurality of threads.
13. The IOL scaffold assembly according to claim 11 , wherein the posterior lens and the secondary lens are parallel and close to each other and the optical axes of the posterior lens and the secondary lens are co-axial when the eye is in a forward gaze position.
14. The IOL scaffold assembly according to claim 11 , wherein the posterior lens and the secondary lens are angled and farther from each other when the eye is in downward gaze position.
15. The IOL scaffold assembly according to claim 11 , wherein the optical axis of the secondary lens is aligned relative to the optic axis of the posterior lens with an off-axis tilt.
16. The IOL scaffold assembly according to claim 11 , wherein the ring platform is configured to be placed in an equatorial region of the capsular bag and wherein the ring platform is configured to fit and grip the anterior capsule and a posterior capsule on the equatorial region.
17. The IOL scaffold assembly according to claim 11 , wherein a rotatable, movable and weighted secondary lens is suspended from a knob of the ring platform by an extendable thread and disposed in between the posterior lens and the anterior ring.
