## Abstract

IOL of the type which include a lens, haptics and a curving ring wherein there are soft haptics and rigid haptics, both being associated through a lever and wherein a softer outer ring houses in its inner geometry an inner curving ring, the latter being rigid and incomplete, with curving flaps in whose geometry the assembly consisting of lens and haptics is housed.

## Claims

### Claim 1

An accommodative intraocular lens, comprising:
a first group including an optical part (1); a soft haptic (14) including an insertion channel and a protrusion, wherein the optical part and the soft haptic are integral; and a rigid haptic (5) including a lever (8) and a thickening portion, wherein the lever is disposed within the insertion channel; and
a second group including a rigid incomplete inner curving ring (9) including a curving flap (10), wherein the curving flap includes a clipping hole; and a soft outer ring (11) including a groove and an angled flap, wherein the incomplete inner curving ring is disposed within the groove;
wherein the first group is connected to the second group when the thickening portion is lodged in the clipping hole and the protrusion is lodged in the angled flap; and
wherein the outer ring and the incomplete inner curving ring are configured to allow changes in a curvature and a thickness of the lens when accommodating and to remain stable when not accommodating.

### Claim 2 (depends on 1)

The accommodative intraocular lens of claim 1, wherein the soft haptic (14) includes a centering hole (4).

### Claim 3 (depends on 1)

The accommodative intraocular lens of claim 1, wherein the soft haptic (14) extends radially from a perimeter of the optical part (1).

### Claim 4 (depends on 1)

The accommodative intraocular lens of claim 1, wherein the soft haptic includes at least two soft haptics.

### Claim 5 (depends on 1)

The accommodative intraocular lens of claim 1, wherein the soft haptic is disposed at an angle of 5° to 180° relative to a horizontal axis (19) of the lens.

### Claim 6 (depends on 1)

The accommodative intraocular lens of claim 1, further comprising an equal number of the soft haptic and the rigid haptic.

### Claim 7 (depends on 1)

The accommodative intraocular lens of claim 1, wherein the thickening portion (7) and the lever (8) are disposed at opposite ends of the rigid haptic.

### Claim 8 (depends on 1)

The accommodative intraocular lens of claim 1, wherein the rigid haptic includes a centering hole.

### Claim 9 (depends on 1)

The accommodative intraocular lens of claim 1, wherein the thickening portion (7) and the lever (8) are disposed on opposite sides of the rigid haptic.

### Claim 10 (depends on 1)

The accommodative intraocular of claim 1, wherein the groove includes an opening oriented to an inside of the outer ring.

### Claim 11 (depends on 1)

The accommodative intraocular lens of claim 1, wherein the angled flap (13) includes a pair of angled flaps and the protrusion includes a pair of protrusions.

### Claim 12 (depends on 11)

The accommodative intraocular lens of claim 11, wherein the pair of angled flaps (13) each include a centering hole (16).

### Claim 13 (depends on 11)

The accommodative intraocular lens of claim 11, wherein each of the protrusions (18) is configured to fasten to one of the pair of angled flaps.
