Problems solved by technology

[0002] Artificial iris is often used in traumatic eyes with complete or partial absence of aniridia. For traumatic eyes with good fundus function, it is often necessary to implant artificial lenses. and the role of intraocular lens, but the implantation of the eye requires a large corneal incision, which brings the risk of low intraocular pressure and explosive suprachoroidal hemorrhage during the operation. Many; there are cases of implantation of intraocular lens and artificial iris in stages, but the second implantation requires scleral flap incision and fixation with ciliary sulcus sutures, which increases bleeding and re-stimulation of ciliary body

Embodiment Construction

[0020] like Figure 1-Figure 5 Shown, the present invention is a kind of artificial iris with capsular bag, comprises top iris 1, bottom iris 2 and four fixing rings 3.

[0021] An inner hole 11 is provided in the center of the top iris 1, and the top iris 1 and the bottom iris 2 outer edges are fixed together to form a capsular bag, and a hole 11 is opened at the junction of the top iris 1 and the bottom iris 2 top for implantation. The opening 12 of the lens 4 .

[0022] Two of the four fixing rings 3 are arranged in parallel up and down, and are respectively fixedly installed on the back side of the bottom iris 2, and are used as feet when sutures are used to fix the artificial iris. In this embodiment, the fixing ring 3 is semicircular with a diameter of 0.2 mm.

[0023] Both the top iris 1 and the bottom iris 2 are made of acrylic material. The color and texture of the front of the top iris 1 are imitated according to the color and texture of the healthy iris collected ...

Abstract

The invention discloses an artificial iris with a capsule, which comprises a top iris, a bottom iris and more than two fixing rings. An inner hole is arranged at the center of the top iris. The capsule is formed when the top iris and bottom iris are fixed, and an incision for implanting intraocular lens is arranged at the connection of top iris and bottom iris. The over two fixing rings are fixedly installed at the back of the bottom iris. The fixing rings as stitches to fix the artificial iris are installed on the back of the body of iris, accordingly the fixing rings, which makes the stitches pierce into the body of iris, are capable of being fixed on the scleral wall. Further, the artificial iris with a capsule utilizes acrylate as material, which make the artificial iris tissue the ultrathin capsule. And the incision only needs 2.8 millimeters even smaller as the folding capsule is implanted. On the second stage, intraocular lens can directly be implanted into the capsule and don't need fixing on the scleral of the eyeball utilizing the threads of polypropylene.
