Definitions

  • the invention relates to a device for folding an intraocular lens with a folding area which has two pivotable half shells which can be pivoted from an open starting position into a closed end position, in which they enclose a guide channel for the intraocular lens between them.
  • the invention further relates to a storage system for an intraocular lens.
  • the device is used to implant a foldable intraocular lens (hereinafter referred to as IOL).
  • IOL foldable intraocular lens
  • the implantation of a temporarily folded IOL is to take place through an approximately 3 mm cut opening in the capsular bag of a patient suffering from cataracts.
  • a container is used in which the IOL is folded, then removed using tweezers and then taken over with the implantation tweezers in the folded state and inserted into the capsular bag.
  • DE 40 39 119 C1 describes a container for this system that is designed to be suitable for folding the IOL. With this system, however, the risk of the lens falling must be taken into account, since it is under mechanical tension when folded. In addition, the surgical method requires some practice.
  • a second system it is provided to fold the IOL in a folding device and to insert the folding device together with the folded IOL in an injection aid, a so-called injector.
  • the injector provides axial propulsion and possibly a further reduction in the cross-section of the lens to be injected.
  • the insertable folding device can also be used as a container for the lens, so that the IOL is not moved by one separate container in the folding device is necessary and the otherwise existing risk of falling does not exist.
  • destruction of the implant cannot be ruled out, but this can only be ascertained when the implant is in the patient's eye.
  • the folding device and the injector form a unit, so that the insertion process is not required.
  • a third injection system can be found, for example, in DE 36 10 925 A1.

It is provided that the device has two pivotably connected half-shells in a folding area, which can be pivoted from an open starting position into a closed end position. In the closed end position, the two half-shells enclose a guide channel for the IOL between them. Furthermore, a film-like band loop is provided in the device, which is fastened to the first half-shell with a fastening end and is displaceably guided on the second half-shell. It is in the open starting position between the Band loop and the two half-shells formed a receiving space for the IOL.

Due to its ability to be moved or swiveled, the side flap can be pushed towards the channel axis of the folding area after folding, so that the step is re-formed and there are smooth and smooth surfaces both inside the channel axis and on the outer circumference of the folding area. The side flap can be locked in the retracted position for a safe folding process.
  • the fastening end is followed by a section of the belt loop, which is articulated to the remainder of the belt loop at a kink that is parallel to the guide channel, and which in the open starting position is directed radially outwards, i.e. away from the half-shell , is oriented.

However, it is always the case that the IOL 56 lies under the strap loop 14 during the complete folding process, which eliminates the risk of pinching lens parts.

  • the folding method described here with the band loop 14 allows the cross-section of the IOL 56 to be reduced to the minimum achievable level, in contrast to other injection systems, a conical progression of the injection channel 2 is not absolutely necessary for the refolding of the IOL 56. The risk of the IOL 56 being destroyed during the final axial propulsion in the injection channel 2 is thus reduced to a minimum.
  • the use of a conical injection channel 2 is still possible in principle and is also independent of its cross-sectional shape.
  • the use of the belt loop 14 has, in addition to the particularly secure folding that is gentle on the IOL 56, the additional advantage that the IOL 56 is already securely held in the receiving space 22 in the open starting position, as shown in FIG. 4 or 11.
  • the folding area 2 with the strap loop 14 is also particularly advantageously suitable for storing and transporting the IOL 56. So that the IOL is held sufficiently securely in the receiving space 22, the strap loop 14 can be tightened somewhat and locked in this state via the locking webs 27 are so that the IOL 56 is biased somewhat and thereby clamped in the receiving space 22.

  • Geometry variants are used. It should be noted that in addition to injury to the IOL 56 during handling, the risk of injury to the patient's eye must be kept low. For this purpose, the end of the injection channel 2 facing the patient has a continuous geometry. In the case of the step 48 used for folding according to FIG. 3, this does not therefore continue to the distal end, that is to the injection tip 32. For this purpose, as shown in FIGS. 3 to 9, the movable side flap 50 is provided. The advantage thus achieved is that the geometry of a thrust ram 68 (cf. FIG. 20) can be adapted well to the internal geometry of the injection channel 2 shown in FIG. 9.
  • the step 48 is restored by inserting the device into the injector, the inner contour of the injector being designed such that the movable side flap 50 is pressed radially in the direction of the channel axis 10 and the step 48 disappears. If an integrated embodiment, as shown in FIG. 2, is used, the step 48 is reduced by means of a shell-shaped element which is pushed over the injector and presses the side flap in the direction of the channel axis 10. If the proposed folding area 4 is realized without the side flap 50 shown in FIGS. 3 to 9 or also without step 48, this adjustment process is omitted.
  • the contour of the injection channel 2 used does not necessarily have to be circular in shape. Possible embodiments are shown in FIGS. 16 to 19, which, however, do not conclusively indicate the possible geometric shapes. It is of crucial importance for all geometrical forms that the distal end of the injection channel 2 has no sharp edges. Sharp edges on the outer surface pose an increased risk of injury to the patient's eye, and sharp edges on the inside can damage the IOL 56.
  • the quadrangular contour shape with rounded edges shown in FIG. 18 represents only one possible embodiment of these geometry variants and can in principle be expanded to an n-square basic shape with round edges in each case.

  • the doctor can then inject the IOL 56 into the prepared patient's eye by first inserting the injection tip 32 of the injection channel 2 into an incision. By continuously pushing the pushing punch 68 onto the IOL 56, the IOL 56 can then be implanted in the prepared capsular bag of the patient's eye.

Abstract

L'invention concerne un dispositif qui fait partie d'un système d'injection servant à injecter une lentille intra-oculaire (56) pliable dans l'oeil d'un homme. Ce dispositif comprend une zone de pliage (4) pourvue de deux demi-coquilles mutuellement reliées de façon à pouvoir osciller que l'on peut faire passer d'une position initiale ouverte à une position finale fermée. Selon l'invention, une boucle de ruban (14) du type film est fixée, par une extrémité de fixation (16), à la première demi-coquille (8a) et guidée de façon à pouvoir coulisser sur la seconde demi-coquille (8b). Dans la position initiale ouverte, un espace de réception (22) est formé entre la boucle de ruban (14) et les deux demi-coquilles (8a, 8b). Lorsqu'on tire sur la boucle de ruban (14) guidée de façon à pouvoir coulisser, les deux demi-coquilles (8a, 8b) sont déplacées en direction de leur position finale. La disposition de la boucle de ruban (14) permet, d'une part, un processus de pliage plus fiable et soigné de la lentille intra-oculaire (56) et, d'autre part, un stockage de la lentille intra-oculaire (56) à l'état non plié dans la zone de pliage (4).
