Embodiment Construction

[0024] like figure 1 A sclera-fixed intraocular lens shown is composed of an optical part 1 and surrounding support loops, the support loops extend radially outward along the optic part, and more than two support loops are provided, and the support loops It is composed of guiding loop 2, fixing loop 3 and connecting loop 4. The fixing loop 3 is roughly in the shape of "λ". The front end of the "λ"-shaped fixing loop 3 extends forward as the guiding loop 2. The branch is connected to the connecting loop 4, and a long branch of the "λ" shaped fixing loop 3 is exposed outside; the fixing loop 3 is connected to the optical part 1 through the connecting loop 4; the guiding loop 2 is used to guide the fixing loop 3 from the inside of the eye It is taken out of the body and needs to be cut off after the operation is completed; the fixing loop 3 is fixed between the layers of the sclera wall; the connecting loop 4 is used to pull the optical part 1 of the intraocular lens, and when th...

Abstract

The invention relates to the field of ophthalmic intraocular lens implantation, in particular to a scleral fixed intraocular lens, which is composed of an optical portion and peripheral supporting rafts, and the supporting rafts extend radially outward along the optical portion, the support rafts are provided with two or more, and the support raft is composed of a guide raft, a fixed raft and a joint raft, and the fixed raft is in a gamma shape; the fixed raft is connected to the optical portion through a connecting raft, and the front end of the fixed raft is provided with the guiding raft. The intraocular lens can support the fixation of the support raft in the eye without suture, significantly reduces the workload of the operation and tissue trauma, reduces the surgical complications and reduces the pain of the patient; at the same time, the dislocation of the artificial lens caused by the dissolution or loosening of a traditional intraocular suspension line can be avoided.

Description

technical field [0001] The invention relates to the field of ophthalmic intraocular lens implantation, in particular to a sclera-fixed intraocular lens, which is used when the lens capsular bag is missing due to various reasons and the traditional intraocular lens cannot be implanted normally. Background technique [0002] The main components of the human lens are protein and water. It will become cloudy due to aging, and the cloudy lens will prevent light and images from projecting to the retina. Medically, the cloudy lens is called a cataract. Eye damage, certain diseases, and even certain drug treatments may cause lens opacity; according to statistics, more than 90% of cataract cases are also caused by the aging process that humans must go through, and the lens of the eye becomes cloudy , and then vision is affected, the mechanism is not yet clear, and no breakthrough has been made in drug treatment so far. The only really effective treatment for cataracts is surgery, wh...
