Abstract

The present disclosure provides an artificial lens fixing sac for fixing an artificial lens for cataract surgery. The artificial lens fixing sac for fixing an artificial lens for cataract surgery of the present disclosure is installed at a position of a lens that is removed by cataract surgery, and the artificial lens fixing sac includes an implantation hole in which an artificial lens, which is inserted into an internal space of the artificial lens fixing sac, is implanted at the position of the removed lens, and fixing threads installed at predetermined intervals on an outer peripheral edge of the artificial lens fixing sac to fix the artificial lens fixing sac to a sclera.

First claim

What is claimed is:

1 . An artificial lens fixing sac for fixing an artificial lens for cataract surgery, which is installed at a position of a lens that is removed by cataract surgery, the artificial lens fixing sac comprising:
an implantation hole in which an artificial lens, which is inserted into an internal space of the artificial lens fixing sac, is implanted; and fixing threads installed at predetermined intervals on an outer peripheral edge of the artificial lens fixing sac to fix the artificial lens fixing sac to a sclera.

2 . The artificial lens fixing sac of claim 1 , wherein the artificial lens fixing sac has a shape in which circumferential surfaces of first and second plates having corresponding shapes are in contact with each other, and the internal space into which the artificial lens is inserted is formed in the shape in which the first and second plates are in contact with each other.

3 . The artificial lens fixing sac of claim 2 , wherein the first and second plates of the artificial lens fixing sac have corresponding shapes and inner surfaces each having a concave disk shape, and an implantation hole is formed at a center of the first and second plates to prevent an increase in intraocular pressure and ensure a flow of water.

4 . The artificial lens fixing sac of claim 3 , wherein one or more marking holes are formed in the first and second plates of the artificial lens fixing sac to set directionality at the time of fixing the artificial lens fixing sac between the implantation hole and the circumferential surface.

5 . The artificial lens fixing sac of claim 2 , wherein the internal space, which is defined as inner surfaces of the first and second plates of the artificial lens fixing sac, which are each formed in a concave disk shape, face each other, includes a guide surface formed to guide a haptic part of the artificial lens and defined as a width of the internal space gradually decreases toward the circumferential surface, and
wherein the circumferential surfaces, which are in contact with each other while defining a curved surface, includes a fixing groove having a valley shape and formed to fix and support the haptic part of the artificial lens.

6 . The artificial lens fixing sac of claim 1 , wherein the artificial lens fixing sac is made of a 20d silicone material so that the artificial lens fixing sac is freely folded or unfolded when the artificial lens fixing sac is mounted in an iris.

7 . The artificial lens fixing sac of claim 3 , wherein the implantation hole is formed at the center of the first and second plates so as to have a diameter of the artificial lens, marking holes are formed at predetermined intervals around the implantation hole, and the marking hole is formed in any one of circular, triangular, quadrangular, and hexagonal shapes.

8 . The artificial lens fixing sac of claim 4 , wherein the marking holes are formed at the predetermined intervals around the implantation hole, and one side of each of the marking holes is cut out toward the implantation hole.
