Description
Technical Field
The invention particularly relates to the technical field of medical instruments, in particular to an artificial lens.
Background
One known method of treating an ocular condition known as cataract is to remove the lens of the eye and use an artificial lens as a substitute for the lens. When using this type of intraocular lens, it is necessary to implant it into the capsular bag from which the nucleus and cortex have been removed. For the patient with insufficient capsular bag support, other methods are needed for implantation, and at present, ciliary suture fixation, scleral interlayer fixation, scleral hooking fixation and the like are mainly adopted. The scleral hook fixing method is an international patent filed by the inventor. The three-piece artificial lens is pulled out of the sclera from two adjacent scleral micro incisions and then turned back to the vitreous cavity to form a fishhook shape, and meanwhile, a scleral lamellar groove is formed between the two adjacent scleral incisions to embed the lens. The method improves stability and centering of artificial lens, has simple operation process, is easy to grasp, and reduces operation time. In the process of applying a scleral hooking fixation implantation method, we find that the existing three-piece type intraocular lens has some defects: first, the length is insufficient. During operation, the tab needs to be pulled out to a sufficient length, if the tab is not long enough, the connection point of the tab and the optical surface can bear larger force, the tab possibly falls off, and meanwhile, the tab at the hook is bent to a larger degree, so that the sclera bears larger force, and the sclera can be broken and damaged for a long time. Secondly, some patients with loose irises are easy to have complications after the irises are embedded in crystals, and the patients have certain uncomfortable feeling. The artificial lens provided by the patent can be well matched with a novel scleral hook implantation method, so that the problems are avoided. Further perfecting the implantation method of the scleral hook, further shortening the operation time, consolidating the curative effect after the operation and being beneficial to further popularization of the method.
