Abstract

The utility model discloses a must climb formula intraocular lens, including optics district, its characterized in that, the edge equipartition on optics district surface is by the climbing of many root hair forms. The whiskers of the utility model are attached and supported on the flat part of the ciliary body to hang and hold the artificial lens on the inner surface of the sclera, so the artificial lens can be reliably fixed in the eye after the removal of the lens without sewing. The utility model is suitable for a cataract patient that lens bag is unusual, can't provide normal support to intraocular lens, this type intraocular lens need not to sew up, can be fixed in the sclera reliably.

Description

Lenticular intraocular lens

Technical Field

The utility model relates to a whisker climbing artificial lens which is used for implanting the artificial lens of aphakic eyes, crystalline lens with damaged crystalline lens bag or turbid crystalline lens.

Background

The conventional intraocular lens comprises a disk-shaped optical zone 1 and 2-4C-shaped lens flaps 2 (shown in fig. 1 as a double-flap intraocular lens) at the outer edge thereof, which are used for lens replacement and implanted into the lens capsular bag. The prior artificial lens has the defects that if the abnormal lens bag is found in the operation process, such as incomplete posterior capsule, the artificial lens is difficult to support, and dislocation can occur after the artificial lens is implanted.

Disclosure of Invention

The utility model discloses the technical problem that will solve is: the existing artificial lens is not suitable for patients with defects of lens capsular bags and is easy to dislocate after being implanted.

In order to solve the above technical problem, the utility model provides a must climb formula intraocular lens, including optics district, its characterized in that, the edge equipartition on optics district surface is by the climbing of many palps forms.

Preferably, the scale on the optical zone is divided into a plurality of clusters, a plurality of scales are arranged in each cluster, and the inclination angle of the scale in each cluster is the same.

Preferably, the optical zone is provided with 2-6 cluster climbers.

Preferably, the end of the flap extends towards the outer edge of the optical zone.

The whiskers of the utility model are attached and supported on the flat part of the ciliary body to hang and hold the artificial lens on the inner surface of the sclera, so the artificial lens can be reliably fixed in the eye after the removal of the lens without sewing.

The utility model is suitable for a cataract patient that lens bag is unusual, can't provide normal support to intraocular lens, this type intraocular lens need not to sew up, can be fixed in the sclera reliably.

Drawings

FIG. 1 is a schematic structural view of a prior art intraocular lens;

fig. 2 is a schematic structural diagram of a whisker climbing intraocular lens provided by an embodiment.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

Examples

As shown in fig. 2, the artificial lens of the whisker climbing type provided for this embodiment includes a disk-shaped optical portion 1, and two clusters of whisker-shaped ridges 2 are symmetrically distributed at the edge of the surface thereof.

The optical area 1 is preferably made of a memory material, such as a three-dimensional covalent network structure formed by cross-linking and polymerizing methyl methacrylate, hydroxyethyl methyl methacrylate, methacrylate hydroxyphenol and ethylene glycol diacrylate. One end of the tab 2 is buried in the edge of the optical region 1, and the material of the end is preferably a high-strength polypropylene material, and the other end is a puncture needle 3 made of stainless steel metal.

The working process of the product is as follows: after the crystalline lens is removed, the artificial crystalline lens is rotationally injected into the posterior chamber of the eyeball, the edge of the artificial crystalline lens is close to the ciliary body area, the position of the artificial crystalline lens is adjusted, the optical area 1 is centered and stabilized, and the implantation of the artificial crystalline lens is finished.
