## Abstract

The invention relates to a device for receiving an intraocular lens, comprising a first and a second half-shell which are connected to each other in an articulated manner by a first joint and which can be moved relative to each other from an open position into a closed position. The half-shells form an open chamber in the open position and an enclosed chamber in the closed position. A covering element is pivotally arranged on the longitudinal side of the first of the two half-shells covering element covering the open chamber in the open position and being positioned substantially outside of the enclosed chamber in the closed position. A movable or pivotal stopper can be provided which delimits the open chamber in the ejection direction of the lens in the open position and is positioned substantially outside of the enclosed chamber laterally to the ejection passage in the closed position.

## Claims

### Claim at position 1

1-50. (canceled)

### Claim 51

A device for receiving an intraocular lens, comprising:
a first half-shell and a second half-shell connected to each other in an articulating manner by a first joint, the first and second half-shells movable relative to each other from an open position to a closed position, the first and second half-shells forming an open chamber in the open position, to allow for insertion of a lens into the open chamber and forming an enclosed chamber in the closed position, the enclosed chamber defining an ejection passage for ejecting the lens from the enclosed chamber; and
at least one stopper displaceably or pivotally arranged on the first half-shell, said stopper bounding the open chamber in the open position and being positioned substantially outside of the enclosed chamber laterally to the ejection passage in the closed position.

### Claim 52 (depends on 51)

The device of claim 51, wherein the stopper is formed on a holding element that bridges or spans the open chamber in the open position and is positioned substantially outside the enclosed chamber in the closed position.

### Claim 53 (depends on 52)

The device of claim 52, wherein the stopper is displaceably or pivotally arranged so that the holding element is displaceable or pivotable on a first longitudinal edge of the first half-shell.

### Claim 54 (depends on 52)

The device of claim 52, wherein the holding element is connected with the first half-shell via a second joint, which forms a hinge.

### Claim 55 (depends on 52)

The device of claim 52, further comprising a bending groove formed on a side of the holding element that turns away an inner surface of the first half-shell.

### Claim 56 (depends on 52)

The device of claim 52, further comprising a holding element support on a second longitudinal edge of the second half-shell.

### Claim 57 (depends on 52)

The device of claim 52, wherein upon closing of the first and second half-shells, the holding element slides over a second longitudinal edge of the second half-shell and out of the closing chamber.

### Claim 58 (depends on 57)

The device of claim 57, wherein in the closed position, the holding element is located substantially outside the enclosed chamber.

### Claim 59 (depends on 58)

The device of claim 58, wherein in the closed position, the holding element is located between first and second wings.

### Claim 60 (depends on 58)

The device of claim 58, further comprising a plurality of holding elements, wherein each of the plurality of holding elements supports at least one stopper.

### Claim 61 (depends on 60)

The device of claim 60, wherein the pat least one stopper comprises a first stopper for a front haptic of the lens and a second stopper for a rear haptic of the lens.

### Claim 62 (depends on 52)

The device of claim 52, wherein the holding element is integrally formed with the first and second half shells.

### Claim 63 (depends on 51)

The device of claim 51, wherein the first and second half-shells each include a support.

### Claim 64 (depends on 63)

The device of claim 63, wherein the support forms a side rail.

### Claim 65 (depends on 51)

The device of claim 51, wherein the enclosed chamber in the closed position of the first and second half-shells forms a loading channel.

### Claim 66 (depends on 51)

The device of claim 51, further comprising first and second wings arranged respectively on longitudinal edges of the first and second half shells.

### Claim 67 (depends on 66)

The device of claim 66, further comprising a closure formed on each of the first and second wings.

### Claim 68 (depends on 51)

The device of claim 51, further comprising a plug device formed on one of the first and second half-shells for inserting into a receiving opening of an injector housing.

### Claim 69 (depends on 51)

The device of claim 51, wherein the device forms a cartridge configured for insertion into an injector.

### Claim 70 (depends on 51)

The device of claim 51, wherein the device comprises a cartridge configured for use with an injector housing and a plunger, the plunger being displaceable in a longitudinal direction in the injector housing.

### Claim 71 (depends on 51)

The device of claim 51, wherein in the closed position of the first and second half-shells, the holding element is clamped between edges of the first and second half shells.
