Definitions
- the invention relates to an intraocular lens having an outer edge.
- Intraocular lenses are usually attached with a special feel in the capsular bag of an eye. Especially when the lenses are very thin, problems arise when attaching the lens to the haptic and placing the haptic in the capsular bag of the eye, which are mainly due to a bending of the implants in the eye.
- the invention has the object to further develop an intraocular lens so that they easier, z. B. without haptics to attach in the eye.
- the outer edge has an adhesive.
- the attachment of an adhesive on the outer edge of the lens makes it possible to fix the lens during insertion of the lens into the capsular bag, preferably without a haptic in the capsular bag. It is advantageous if the adhesive fixes the lens in the capsular bag at least until a firm connection has formed between the lens and the capsular bag as a result of the healing of the procedure. It is desirable if the fixation is permanent.
- a simple procedure when inserting the lens results from the fact that the adhesive is activated.
- the adhesive may be exposed through a peelable top layer, such as a silicone film, just prior to surgery. As a result, contamination of the adhesive is avoided before activation. However, the adhesive is only secondary z. B.
- irradiation such as UV light or heat activatable to convert the adhesive into a sticky form or cure by the irradiation.
- Other options for activation include treatment with microwaves or moisture.
- the adhesive is thus either directly active or secondarily activated.
- the provision of the adhesive between the lens and the capsular bag further prevents cells between the lens and the capsular bag from penetrating from the area in front of the lens into the area behind the lens.
- the provision of an adhesive between the intraocular lens and the capsular bag thus prevents the risk of after-stars caused by the turbidity on the lens back by such cells.
- the adhesive be applied as a closed line.
- the closed line makes it possible to securely seal the space in front of the lens against the space behind the lens by means of the glue.
- the secure hold of the lens in the capsular bag and the Ve ⁇ neiden of migratory cells is also achieved in that the edge of the intraocular lens has an edge.
- the fact that the rounded surfaces of the lens leak at the edge into an edge, a better anchoring of the lens in the capsular bag and a better seal between the capsular bag and lens is achieved.
- the edge has an acute angle. This makes it possible to firmly anchor the lens in the capsular bag.
- the lens is foldable or injectable.
- the attached drawing shows a Ausfiilirungsbeispiel an intraocular lens according to the invention.
- FIG. 1 is a schematic plan view of an intraocular lens
- FIG. 2 shows a section through the intraocular lens shown in FIG.
- the intraocular lens 1 is made of polymethyl methacrylate (PMMA). But it can also be made of silicone, other acrylics, polyurethane or other materials.
- PMMA polymethyl methacrylate
- the section shows the lenticular shape. In the plan view, the lens is circular. It therefore has a nikfö ⁇ nigen outer edge 2, which in the present case has a sharp edge with an angle 3 of about 45 °. For very thin lenses, the angle 3 to be measured at the edge is less than 45 °.
- the circular edge 2 abuts against the capsular bag 4 indicated in the figure and on both sides of the edge 2 adhesive surfaces 5 and 6 are arranged annularly, which allow the lens 1 to be bonded to the capsular bag 4.
- the adhesive can also be attached only on one side of the lens or directly on the edge of the lens.
- the adhesive is cured with UV light.
- the plano-convex intraocular lens 7 shown in FIG. 3 has a holding web 8 which is fastened to the intraocular lens 7 and has an adhesive edge 9.
- the adhesive edge is arranged in this exemplary embodiment on the retaining bar radially outside the lens area. It runs in such a way subsequent to the course of the convex side of the lens, that behind the lens, a cavity 9 is formed.
