Definitions

  • the invention relates to a deformable artificial intraocular eye lens with a deformable optical zone part for implantation during a cataract operation, which has a lens and a haptic connected to it from a plurality of angular elastic support elements.
  • Such artificial eye lenses are used to replace the natural human lens when the latter has been removed.
  • the artificial intraocular eye lens serves as a device for optical correction of the eye instead of the natural lens.
  • This surgical implantation of an artificial intraocular eye lens after the removal of the natural human lens is a method for optical correction that has already proven itself successfully in the field of ophthalmology.
  • the known artificial intraocular eye lenses there are different designs which are based on the various methods by which the implant is fastened and stabilized within the eye in such a way that the central lens body is held in a stable position with respect to the pupil and the optical axis of the eye .
  • the type of artificial intraocular lens is classified according to the position of the implant within the eye, depending on whether the implantation is in the anterior chamber, in the iris plane or in the posterior chamber, here in the sulcus ciliaris or capsule sac.
  • the artificial intraocular eye lens can be attached by:
  • Such intraocular lenses are made both from solid material (PMMA) and in the form of foldable lenses (HEMA, silicone, acrylic), which are available either dry or in a moist medium.
  • Lenses made of solid material have the disadvantage, which is particularly serious for the patient, that when they are implanted in the eye, an implantation opening corresponding to the diameter of the intraocular lens (approx. 5 to 7 mm) is required, while in the case of foldable lenses, only one implantation opening of approx. 2 , 8 to 3.2 mm diameter is required.
  • boat lenses in which the haptics are molded onto the lens in the form of relatively wide elements, as well as lenses which are provided with a holding part formed concentrically around the actual lens.
  • a lens is described in DE-OS 33 03 803.
  • the same disadvantages of the lenses with two haptics occur, in the latter the adhesion of the front and rear capsule sheets is deteriorated, and poorer centering is also a disadvantage.
  • DE-OS 27 49 726 describes an artificial intraocular eye lens which can be used in one embodiment in the rear eye chamber and in another modified embodiment in the front eye chamber.
  • the mounting part of the second position-setting part can be modified in order to sew it onto the iris in front of it or to be able to fasten it in the manner of a card tab without sewing on the iris.
  • the bearing part of the first position setting part remains unchanged and therefore the eye lens is also arranged in the rear eye chamber.
  • This eye lens therefore requires two different embodiments for use in the anterior or posterior chamber.
  • it has only a limited degree of flexibility because the storage part of the first position setting part is unlikely to be movable relative to its base. A certain degree of flexibility is desirable for the reasons set out above.
  • GB 20 55 585 and US Pat. No. 42 54 509 describe artificial intraocular eye lenses which can only be used in the anterior chamber. Although these lenses have flexibility, this is limited by the extent to which the lens body can move forward. Forward movement of the lens body can be dangerous for the cornea. In addition, these known lenses have a four-point attachment, which can lead to the fact that the pressure on the tissue is concentrated in the four rather narrowly delimited points, which can lead to tissue damage.
  • an artificial eye lens with a lens body and three support elements is known, one of which is designed as a closed bracket with both ends on the edge of the lens body, extending over a sector of the lens body, and of which the two other support elements are attached to the edge of the lens body opposite the bracket.
  • This known eye lens has two further, on the side opposite the closed bracket, also trained bracket. All temples are curved outwards. The total width of the two last mentioned brackets is larger than the diameter of the lens body, so that the eye lens can only be inserted through the pupil into the rear eye chamber by stretching the iris, since folding of the lens is also not possible.
  • FIG. 12 of the same publication which has two closed brackets which are fastened on opposite sides of the lens body and which extend over a sector of the lens body and have a concave region drawn in towards the lens body. Due to the shape of these two brackets, this lens can easily be inserted through the pupil into the rear chamber of the eye.
  • the distances between the two support points of the two brackets are, however, comparatively small due to their construction, so that, with a small diameter of the eyes, the tissue can also be overstretched in one direction and, with a relatively large diameter, the lens body can be decentered.
  • DE-OS 34 15 815 describes an artificial eye lens in which the closed bracket has a concave region drawn in towards the lens body and the two other support elements are designed as hook-shaped brackets bent on opposite sides.
  • This lens has the disadvantage that it cannot be rotated or folded when inserted.
  • DE-AS 10 34 325 describes a lens which is arranged in the front eye chamber and is held by elastic loops lying in the front eye chamber angle.
  • This intraocular lens is easy to use, its correct fit can be easily checked at any time, and displacements can be determined immediately.
  • the loops if they are elastically deformed by the forces exerted by the eye or eye chamber angle, bulge perpendicular to the plane of the iris in the direction of the cornea and can come into contact with the extremely sensitive inside of the cornea or bring the lens part into contact with this inside. This bulge is further promoted by the fact that the forces exerted by the angle of the eye chamber have a component directed towards the cornea.
  • the loops In order to exclude contact with the inside of the cornea with certainty, the loops have been arranged in the rear eye chamber despite great difficulties when inserting them, the optical lens part being able to be positioned in both the front and rear eye chambers (DE-OS 30 13 177) and S-shaped loops can be used (NL - OS 80 04 782, corresponds to the subsequently published DE OS 30 32 144).
  • an artificial eye lens is known, in which the presence of the lens and support feet outside the pupil is assumed and the lens body is provided with at least one loop-shaped foot for the execution of a seam that holds the eye lens on the rainbow skin. There is a possibility of dislocation when dilating the pupil if the lens is inserted into the iris.
  • the upper loop-shaped foot represents two lobes that lie opposite each other in the upper half of the horizontal lens plane, while the plane of this loop-shaped foot is inclined at an angle of 5-8 degrees to the lens plane in order to achieve a resilient effect .
  • the disadvantage of this known eye lens is that it requires the formation of a large coloboma (with a length of up to 4 mm) in the upper part of the iris with subsequent application of a supramid suture, which significantly increases the duration of the surgical intervention and additional technical difficulties during implantation.
  • the shape of the two support loops is essentially the same except for a notch in a support loop.
  • the notch is sewn onto the iris of the eye. Because the lens loops are rigid, inserting the lens requires a fairly large deformation of the iris and capsule, which can damage the eye. Furthermore, the contact area of the support loops with the inside of the capsule is small, as a result of which the lens can shift due to vibrations that occur when walking or running.
  • intraocular lens implants which offer the clinical advantage of relatively small incisions, but whose optical area has a fixed focal length and which maintain a prescribed shape in the implanted state, so that one can use safe and more expedient surgical techniques and a comfortable fit keeps in mind.
  • the known folding lenses are either difficult to fold by flat haptics or the haptic elements protrude from the implantation zone when folding and / or passing through the incision of the implantation opening in the eye, which complicates the implantation and an additional risk of injury to the eye and a risk of damage to the Haptics are inherent.
  • the invention is therefore based on the problem of creating an artificial intraocular eye lens which allows problem-free passage through the smallest possible sclerocorneal or corneal implantation opening in the eye, as well as a simple unfolding process with little stress on the touched structures of the eye, a slight turning at the implantation site, So in the capsular bag, sulcus or chamber angle and a safe centering with easy opening of the capsule.
  • the mechanical stress on the eye tissue by the fastening elements of the lens should be kept low.
  • the described lens structure according to the invention has a deformable optical zone region, through which the lens can be deformed by folding to a width of approximately 50% of the cross-sectional diameter of the optics when inserted into the eye. After insertion, the lens returns to its original full size and fixed focal length. It can therefore be used through smaller incisions in the eye tissue than is possible with a rigid lens of comparable size. It has four angular elastic haptic elements connected to it for four-zone support or storage, which are separated peripherally from one another, all arranged in one direction of rotation in such a way that the haptic elements come to lie in the implantation area without additional manipulations in the folded state.
  • the haptic elements advantageously have a long curved area which extends on a peripheral line around the center of the eye lens. This results in a more precise fixation and centering of the lens and a lower contact pressure by the haptic elements on the eye tissue.
