Annular bag of intraocular lens

Abstract

The invention discloses an annular bag of an intraocular lens. The annular bag comprises a bag body provided with an anti-migration structure and a heparin coating; the bag body is internally matchedand implanted with an intraocular lens, and the periphery of the intraocular lens is provided with strip-shaped flaps made of acrylic ester. According to the invention, the anti-migration structure isused for blocking epithelial cells, so that the epithelial cells cannot migrate towards the center depending on the front surface and the rear surface of the intraocular lens, and thus the central part of the intraocular lens is prevented from becoming opaque to cause occurrence of vision diminution, namely posterior cataract. The strip-shaped flaps are arranged on the periphery of the intraocular lens, so that the intraocular lens does not need an additional fixing structure, the structure of the annular bag is simplified, operation steps are reduced, and the operation progress is accelerated. In addition, the internal surface of the bag body is provided with the heparin coating, and then the viscosity of epithelial cells attached to the surface of the intraocular lens at the equatorialpart of the annular bag is reduced, so that the epithelial cells and the annular bag are not adhered to each other easily, and replacement of a second-stage intraocular lens is facilitated.

Description

technical field [0001] The invention relates to the technical field of intraocular lenses, in particular to an annular capsular bag of an intraocular lens. Background technique [0002] The existing method for treating cataract is to implant an intraocular lens into the annular capsular bag of the human body through surgery to improve the patient's vision. [0003] However, because the equatorial epithelial cells of the annular capsule have the ability to proliferate, after cataract surgery, as time goes by, they will continue to proliferate and differentiate, form fibroblasts, and migrate to the posterior and anterior capsules of the lens, resulting in Become opaque, leading to vision loss, clinically known as post-cataract. [0004] In addition, most children need to replace the artificial lens in the later stage due to the mismatch between the eyeball development and the implanted artificial lens. [0005] In view of this, the present inventor has made in-depth ideas fo...

[0003] However, because the equatorial epithelial cells of the annular capsule have the ability to proliferate, after cataract surgery, as time goes by, they will continue to proliferate and differentiate, form fibroblasts, and migrate to the posterior and anterior capsules of the lens, resulting in Becomes opaque, leading to vision loss, clinically known as posterior cataract

[0004] In addition, there are also most children who need to replace the intraocular lens in the later stage due to the mismatch between the eyeball development and the implanted intraocular lens. However, due to the tight adhesion between the intraocular lens and the human body's own lens capsular bag, the intraocular lens cannot be replaced
