Artificial intraocular lens capsular sac adopting loop filaments for intraocular fixing

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 on the 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

Intraocular lens capsular bag fixed with loop wire technical field 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 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. 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: The clamping method is to attach the intraocular lens to different layers of the tissue, such as the iris clamping the intraocu...
