Definitions

• the present invention relates to an insertion assembly for an IOL (intraocular lens) comprising an insertion device for inserting an intraocular lens (IOL) comprising a pointed or tip-shaped insertion part with an insertion channel and a folding part located upstream thereof, said folding part comprising a first wing part, which is rigidly connected to said insertion part, and a second wing part which is hingingly connected to said first wing part, wherein each of the wing parts comprises a receptacle part, said receptacle parts together forming a receptacle for a folded IOL, and also retainer means for the IOL, to be fitted on a wing part, said retainer means comprising engagement means for engaging with said wing part.
• IOL intraocular lens
• Such an insertion assembly is disclosed in US 6,129,733.
• intraocular lenses are supplied in a separate packaging. There may possibly be an insertion device with said packaging.
• the lens is subsequently removed from the packaging (may be a bottle filled with fluid) and placed in the insertion device. Only afterwards is the lens folded and put into the eye with the aid of an injector. As a result of this the lens is in the adverse position of being folded up for only a very short time.
• an insertion assembly wherein with the aid of the retainer means the lens is already positioned in the correct position in the insertion device.
• the retainer means prevent the lens escaping from the insertion device.
• the insertion device can be in the desired open position, in other words in the optimum position for the lens, so the optical properties thereof are not disadvantageously influenced. Because it is supplied in this way, it is no longer necessary to place the lens in the insertion device at the site of use, since it is already in the insertion device. It is necessary only to remove the retainer means from the insertion device at the moment of use. This can be done by a simple sliding, snapping or clicking action.
• the positioning of the lens inside the insertion device is admittedly less secure, but during or immediately after the retainer means have been removed the wing parts of the insertion device are moved towards one another, resulting in the lens being securely locked in the insertion device. Subsequently the movement of the lens into the eye through the p ⁇ intof the insertion device can take place in the normal way with an injector.
• the width of the retainer means is substantially identical to the width of the wing part concerned or smaller.
• the retainer means have a dimension which is just sufficient for handling thereof but a dimension which is far smaller than the construction of the accessory shown in American patent specification 6,129,733.
• the retainer means can be fitted to either the wing part fixed with respect to the pointed insertion part or to the hinged wing part. However, it should be understood that the retainer means are fitted to only one of these wing parts.
• the retainer consists of a first part extending from the engagement elements and a second part extending therefrom.
• the length of the two parts is identical, wherein the first part extends towards the receptacle for the lens part and the second part extends outwards.
• the first part can, moreover, be provided with a recess for the lens part for positioning it in a secured manner.
• the receptacle part is provided near the hinge between the wing parts with an elevation supporting the IOL.
• This protects the IOL.
• this has the effect that when the plunger is moved into the injector it is certain that the plunger engages with the lens with the front face thereof and the lens does not get stuck between the plunger and the receptacle. It is also possible to provide meticulous guiding for the plunger.
• by means of such an elevation the friction drag between the IOL and the receptacle is reduced. It should be understood that the use of such an elevation can also be executed separately from the measures described in Claim 1 and express rights are requested for this.
• locking means to lock the two wing parts jointly after they have been moved towards one another.
• These locking means are preferably executed such that one of the locking means comprises an elevation and the other a corresponding recess, wherein said locking means can click or snap into one another.
• the elevation is preferably fitted on the wing part that is not provided with the retainer means and positioned such that it cooperates with the retainer means. Consequently the wing parts cannot be moved towards one another because the locking cam concerned strikes against the retainer means. The user will then clearly understand that before he can move the wing parts closer together it is first necessary to remove the retainer means.

• the insertion device comprises a hinge and the first part extends as far as in front of said hinge.
• the receptacle part is provided near said hinge between said wing parts with an elevation supporting an IOL.
• the first part comprises a rim extending in the direction of the insertion channel, preferably an end rim which extends as far as between the supporting elevation and a hinge. In one embodiment the first part extends as far as over approximately a quarter of the

• IOL intraocular lens
• the invention also relates to a packaging comprising a holder part with an insertion part fitted therein for inserting an intraocular lens (IOL) comprising a pointed insertion part with an insertion channel and a folding part located upstream thereof, said folding part comprising a first wing part which is rigidly connected to said insertion part and a second wing part which is hingingly connected to said first wing part, wherein each of the wing parts comprises a receptacle part, said receptacle parts together forming a receptacle for a folded IOL, and also retainer means for the IOL, fitted to one wing part, said retainer means comprising engagement elements for engaging with said wing part and a lock placed on said holder part.
• IOL intraocular lens
• the combination of lens and insertion device is delivered to the site of use in the desired position by the presence of the retainer means.
• the packaging may be a sterile packaging. If the lens is a hydrophilic lens it may be packed in a fluid. In order to pack the construction consisting of lens insertion device and retainer means stably, the holder part of the packaging may be provided with guides for clamping accommodation of both the retainer means and the insertion device. The lens is not, of course, touched by the packaging.
• FIG. 1 shows in perspective the insertion assembly according to the invention
• Fig. 2 shows a detail of Fig. 1 ;
• Fig.3 shows an injector combined with the insertion device according to the invention
• Fig.4 shows placing of the insertion assembly in a packaging
• Fig. 5 shows the opened packaging in top view and Fig. 6 shows the closed packaging ready for transport.
• FIG. 1 an insertion assembly according to the present invention is illustrated by 9. This consists of an insertion device or cartridge 10 and retainer means or a retaining Hp 11.
• the insertion device 10 consists of a pointed part 19 which is inserted into an incision in the eye.
• This part 19 is provided internally with an insertion channel 23.
• Part 19 is rigidly connected to a wing 12.
• Wing 13 is hingingly connected to wing 12 by hinge 14.
• Whig 12 is provided with an upright, slightly undercut locking cam 16.
• Wing part 13 is provided with a corresponding slightly undercut recess 17. Consequently the two wing parts can snap into one another.
• Lip 11 is provided with a first part 31 and a second part 32.
• the first part 31 projects slightly into the space delimited by the receptacles 29 and 30.
• Part 31 is provided with a recess 18, by which an intraocular lens indicated by 21 can be accommodated in a secured manner.
• the haptics of the IOL 21 are indicated by 22.
• Lens 21 is additionally locked to some extent between grooves 20 fitted to each wing. This locking is, however, insufficient for the transport of lens 21. Therefore, according to the present invention a retaining lip 11 is fitted. As appears from Fig. 2, the retaining lip is provided with hook-shaped parts 25 which engage under the wing 13.
• a lens 21 has to be inserted in the eye, the wings 12 and 13 are moved out of the position shown in Fig. 1 towards one another. At the same time the lens will be folded over. This is further encouraged by the guide of the first part 31 of the retaining lip 11, since it presses the lens downwards into the receptacle 30 on approximately a quarter of the lens. Complete closing of the wings 12 and 13 is not possible because cam 16 strikes against retaining lip 11. At that moment it is, however, certain that the lens is retained in a secured manner inside the receptacle delimited by the receptacle parts 29 and 30 and by the grooves 20. Subsequently retaining lip 11 is removed by the nursing staff by simply pushing it in the direction of arrow 26.
• the wings 12 and 13 can be moved closer together when parts 16 and 17 are locked. Subsequently opening is no longer possible.
• the various elements are placed in the injector 27. This is provided with a plunger 28. Because the lens in the rolled up state rests on the elevations 15, the injector will always engage with the IOL 21 and the IOL is prevented from getting stuck between the front of the plunger 28 and the wall of the receptacle parts 29, 30.
• Fig. 4 shows that the construction 9 including IOL 21 is fitted in the holder 2 as a whole at the place of production.
• Said holder 2 as is seen in Fig. 5, is provided with ribs 4 with grooves 5 for secured positioning of both the insertion device 10 and the retaining lip 11.
• Retaining lip 11 and insertion device 10 are here already in the position shown in Fig. 1 with respect to one another.
• a lid 3 is placed, possibly after the holder 2 has been filled with a fluid.
• the various elements can be sterilised in the normal way.
• packaging can also be designed such that the injector is included in it
