Problems solved by technology

[0005] The suture fixation method is to pass the suture through the tissue and fix the artificial graft through a thread knot. This method has low requirements on the integrity of the tissue, but it is very difficult to tie a knot in the closed space of the eye, and the operation is difficult. Large, the operation time is more than ten times that of the loop support method

Embodiment 1

[0029] Depend on figure 1 IOL capsular bag plan shown and figure 2 It can be seen from the sectional view of the intraocular lens capsular bag that the intraocular lens capsular bag includes a capsular bag part 1 and a loop wire 2 for fixation; wherein the capsular bag part 1 is a transparent bag composed of an anterior capsule 11 and a posterior capsule 12, and the anterior capsule There is a hole 3 in the center of the membrane 11; the outer diameter of the pouch part 1 is 11 mm, and the thickness is 0.4 mm; the diameter of the central hole 3 is 5 mm. There are also three small holes 4 distributed on the anterior capsule 11, and the diameter of each small hole 4 is 0.2 mm.

[0030] The number of loop wires 2 for fixation is 4, distributed centrally symmetrically, each loop wire has a length of 6 mm, a thickness of 0.3 mm, and a width of 0.4 mm, and there are two enlarged parts 5 on the loop wires. The top 6 of the wire is a barb-like structure that prevents slippage.

Abstract

The invention relates to an artificial intraocular lens capsular sac adopting loop filaments for intraocular fixing, which comprises a capsular sac part and loop filaments for fixing. The capsular sac part is a transparent sac consisting of a front capsular membrane and a rear capsular membrane. The center of the front capsular membrane is provided with a hole. Small holes are also distributed onthe front capsular membrane. More than one loop filaments for fixing are distributed in a central symmetry manner. Body parts of the loop filaments are provided with expanded parts. The artificial intraocular lens capsular sac can be used for treating aphakia without the intraocular lens capsular sac.

Description

technical field [0001] The invention relates to an artificial lens capsular bag, in particular to an artificial lens capsular bag which is fixed inside the eye with a loop wire. Background technique [0002] Cataract is a common eye disease. During the treatment of cataract, the intraocular lens needs to be fixed in the capsular bag of the natural lens through loop support. Lesions, trauma, or surgical complications may damage the lens capsular bag or the zonular ligaments that hold it in place, making it impossible for the IOL to fit into the lens capsular bag. [0003] At present, when the capsular bag of the lens or the zonule is damaged and the intraocular lens implantation in the capsular bag cannot be performed, there are mainly several ways to fix the intraocular lens: clamping method and suture fixation method: [0004] The clamping method is to attach the intraocular lens to different layers of the tissue, such as the iris clamping the intraocular lens or the capsu...
