Artificial sac

Abstract

The invention discloses an artificial sac which comprises a front-layer envelope and a rear-layer envelope. The peripheral edge of the front-layer envelope and the peripheral edge of the rear-layer envelope are fixedly connected with each other, a fixing portion for fixing the artificial sac is arranged on the outer periphery of a joint, the front-layer envelope and the rear-layer envelope are soft transparent envelopes, and an avoiding hole for bringing convenience for artificial lens implantation is formed in the middle of the front-layer envelope. The artificial sac has the advantages thatthe peripheral edge of the front-layer envelope and the peripheral edge of the rear-layer envelope are fixedly connected with each other to form a complete sealed bag, the front-layer envelope and therear-layer envelope are the soft transparent envelopes, and accordingly the artificial sac can be implanted into an eye via a small incision and can be fixed to the eye of a patient by the aid of thefixing portion; the location of an artificial lens can be guaranteed by the artificial sac after the artificial lens is implanted into the artificial sac from the avoiding hole, and the artificial lens is positioned in the middle of the visual axis and is perpendicular to the visual axis, so that light rays which are transmitted into the eye can be focused and can be guided onto the retina.

Description

technical field [0001] The invention relates to the technical field of eye medical devices, and more specifically, relates to an artificial pouch. Background technique [0002] In cataract surgery, the treatment method often used is to remove the cataract and then implant an intraocular lens, which focuses the light entering the eye and guides it to the retina. [0003] It can be understood that after the implantation of the intraocular lens, the eye needs to have a relatively complete capsular bag to ensure the position of the intraocular lens, so that the intraocular lens can focus the light entering the eye. However, in reality, many patients have capsule rupture or loss due to trauma and other reasons, so they do not have a capsular bag to keep the intraocular lens in the center. In these patients, the current commonly used surgical method is intraocular lens suspension. Although this can solve the problem of fixing the intraocular lens in patients with ruptured or miss...

AI Technical Summary

Problems solved by technology

However, in reality, many patients have ruptured or lost capsules due to trauma and other reasons. Therefore, there is no capsular bag to keep the intraocular lens in the center.

In these patients, the current commonly used surgical method is intraocular lens suspension. Although this can solve the problem of fixing the intraocular lens in patients with ruptured or missing capsules, it is difficult to make the lens in the center of the visual axis and perpendicular to the visual axis, so , cannot guarantee the proper position of the lens
