Definitions
- the present invention relates to an implant for implanting in an eye and / or on an eye with fixing means arranged in a first plane and a recess extending substantially in the first plane.
- the known implants have a pressure sensor for measuring intraocular pressure and a pressure sensor for measuring intraocular pressure and a pressure sensor for measuring intraocular pressure and a pressure sensor for measuring intraocular pressure.
- Telemetry coil for transmitting the measured data obtained to a data reader on. They are intended for implantation in the sulcus ciliaris of the eye in a human patient, wherein a foldable plastic ring containing the pressure sensor and the
- Telemetriespule can be deployed so that the plastic ring is fixed on the furrow bottom in the sulcus ciliaris.
- the known implants there is a potential risk that injury to the iris and increased intraocular pressure in a patient may occur due to the uveal contact.
- Another disadvantage is that the eye must be measured consuming before implanting one of the known implants, so that a suitable implant for fixation can be selected on the basis of the size of the implants relevant beef diameter. Concretely, therefore, there is the danger in the known implants that they are poorly fixed. The danger associated with the known implants of a defective fixation can have serious consequences for a patient. Because with a poor fixation can after the Implantation migration and / or rotation of the known implant occur by it and, where appropriate, the sensor attached to it together with the telemetry unit penetrates into the ocular tissue and / or the iris. An increase in the intraocular pressure, defects in the iris or shading of the optical axis of the eye are possible consequences.

- FIG. 7 shows in a sectional view the implant 104 from FIG. 6. It can be seen from FIG. 7 that the compression springs 105 deform back to an extent when the elastic deformation in a plane 109 which is perpendicular to the optical axis 101 is such that the bow section 108 the compression springs 105 is pressed against the groove bottom 107 of the capsular bag 168, after which the implant 104 is fixed transversely to the direction of the optical axis 101.
- FIGS. 8 to 11 show different views of a further implant 100 according to the invention. Analogous to the implant 104 of Figures 6 and 7, the implant 100 according to the figures 8 to 1 1 of two compression springs 1 1 1 and one with the compression springs 1 1 1 integrally formed plate 1 12.
- the plate 1 12 is not a shown adhesive connection with a sensor telemetry module 1 13 connected. In the holes of the plate 1 12 shown in Figure 10 adhesive has flowed in the liquid state, so that the sensor telemetry module 1 12 is additionally anchored on the subsequently cured in the holes adhesive with the plate 1 12.
- the implant 100 can be so above the bracket sections 1 15 15 fix by means of elastic deformation of the compression springs that the strap sections 1 15 along the optical axis of the eye (see Figure 7) are arranged closer to the iris, as the plate 1 12 and the sensor telemetry module 1 13 of the implant 100th
- FIG. 12a shows a schematic representation of an implant 17 according to the invention in a further preferred embodiment.
- the implant 1 17 has a plate 127 which is connected to a Cioni-like capsular tension ring 120 via the support arms 122.
- the plate 120 is spaced parallel to the direction vector 123 perpendicular to the capsule tension ring 120.
- the implant 1 17 is in the groove bottom, not shown, also not shown
- FIG. 12b shows a schematic representation of a further implant 1 18 according to the invention.
- the implant 1 18 consists in addition to a plate 128 of two compression springs 121, which fix the implant without the help of a Cioni capsular tension ring in the furrow bottom of the capsular bag.
- the plate 128 of FIG. 12a Analogous to the implant 17 of FIG. 12a, the plate 128 of FIG. 12
- FIG. 13 shows a representation of an implant 130 in a further preferred embodiment according to the invention.
- the implant 130 consists of a perforated plate 131 and compression springs 132 with bracket portions 133 provided for attachment to the furrow bottom of the capsular bag, which can be deflected by elastic recovery of the compression springs 132 in the direction of the groove bottom of the capsular bag.
- Figure 14 shows a sectional view of the implant 130 of Figure 13.
- the sectional view of Figure 14 can be seen that in the Implant 130, a pressure sensor 134 together with a
- Induction coil 135 which telemetrically transmits measured data detected by the pressure sensor to a receiver is surrounded by a polymer matrix 136, so that the pressure sensor 134, the induction coil 135 and the plate 131 are present as a one-piece component in the implant 130.
- the polymer matrix 136 could flow in the liquid state into the holes of the plate 131, after which the pressure sensor 134 and the
- Induction coil 135 is anchored via the polymer matrix 136 in the holes of the plate 131 with the plate 131.
- the polymer matrix 136 consists of silicone rubber.
- FIG. 15 shows a schematic plan view of another implant 137 according to the invention.
- the implant 137 is formed according to Figure 15 from analog to the implants of Figures 5 to 14
- Compression springs 139 and a frame 138 which is open on one side, in which, according to the sectional view from FIG. 16, a pressure sensor 141 embedded in a polymer matrix 140 of silicone rubber, together with a
- Induction coil 142 is held.
- the polymer matrix 140 was thus introduced into the frame 138 at the open side of the frame 138.
- the implant 137 is thus constructed modularly, namely from a module consisting of the compression springs 139 and the frame 138 and a removable module from the frame 1 18 module consisting of the pressure sensor 141 and the induction coil comprising polymer matrix 40 made of silicone rubber.
- FIG. 17 shows a schematic plan view of a further implant 243 according to the invention with a frame 244 which, in contrast to the frame 138 of the implant 137 according to FIGS. 15 and 16
- Polymer matrix 145 stored, in which a pressure sensor 146 and a Induction coil 147 is embedded.
- the sectional illustration of the implant 143 from FIG. 18 shows that the polymer matrix 145 is mounted in a form-fitting manner in the frame 144 of the implant 143, either by means of a groove (FIG. 18, top), or that the frame 144 fits into the frame 144
- Polymer matrix 142 is completely embedded ( Figure 18 in the middle), or that the frame 144 is partially embedded in the polymer matrix 145 ( Figure 18 below) by placing a rail 147 of the frame outside the polymer matrix ( Figure 18 below).
- FIG. 19 is a sectional view of an implant 148 in which a pressure sensor 149 and a planar coil 150 serving as a telemetry unit together with a holding frame 151 in a
- Polymer matrix 152 is embedded.
- FIG. 20 is a sectional view of an implant 154 designed analogously to the implant 48 from FIG. 19, but in which a coil 153 is embedded in a polymer matrix 155.
- FIG. 21 shows a schematic representation of a plan view
- Implant 156 in which a one-piece compression spring 157, which consists of a thread, is embedded at a portion 158 in a polymer matrix 159 together with a coil 160 and a pressure sensor 161.
- the implant 156 has a particularly compact and thus advantageous for implantation construction.
