Small incision implanted ciliary groove fixing artificial lens stent

Abstract

The invention discloses a small incision implanted ciliary groove fixing intraocular lens stent which comprises a stent ring, a first stent loop and a second stent loop are arranged on the outer side of the stent ring, the two ends of the first stent loop and the two ends of the second stent loop are each of a Z-shaped structure, and the outer side of the first stent loop and the outer side of the second stent loop are used for being placed on a ciliary groove. By the adoption of the structure, the surgical operation steps of implanting the intraocular lens after the cataract surgery of complex cases are simplified, damage to eyeballs is reduced, and the stability and neutrality of fixing the intraocular lens in ciliary sulcus after the surgery are improved; and moreover, the stent type design is adopted, different types of intraocular lenses with different functions can be replaced according to the vision requirements of patients in the short-term and long-term operation.

Description

technical field [0001] The invention relates to the field of intraocular lens bracket fixation, in particular to a ciliary sulcus fixed intraocular lens bracket implanted through a small incision. Background technique [0002] After the current ophthalmic cataract surgery removes the cloudy lens, if the patient's zonule or capsular bag is damaged and the intraocular lens cannot be fixed in the capsular bag, the intraocular lens can only be implanted and fixed in the ciliary sulcus. However, the intraocular lens implanted in the ciliary sulcus currently faces several problems: 1. It is necessary to make a scleral incision, and then fix the intraocular lens with sutures under the episcleral conjunctiva, and the operation is cumbersome; 2. The intraocular lens with the ciliary sulcus fixed After the operation, the sutures will fall off, and the intraocular lens will be misplaced or tilted, which requires a second ophthalmic surgery; 3. At present, there is no special design for...

Problems solved by technology

However, the intraocular lens implanted in the ciliary sulcus currently faces several problems: 1. It is necessary to make a scleral incision, and then fix the intraocular lens with sutures under the episcleral conjunctiva, and the operation is cumbersome; 2. The intraocular lens with the ciliary sulcus fixed After the operation, the sutures will fall off, and the intraocular lens will be misplaced or tilted, which requires a second ophthalmic surgery; 3. At present, there is no special design for the intraocular lens bracket fixed in the ciliary sulcus; 4. At present, there is no There is no intraocular lens design that can replace different types of optics after surgery
