Compared with the conventional viscoelastic agent injecting method for lubricating and injecting an intraocular lens in an intraocular lens implantation operation clinically, the intraocularlens preassembled injector capable of realizing the function of preassembling the viscoelastic agent and the method for loading the viscoelastic agent in the intraocular lens preassembled injector are safer, simple, sterile and high in reliability and save resources.

Description

technical field [0001] The present invention mainly relates to the field of artificial lens implantation. Specifically, the present invention relates to an intraocular lens preloaded syringe capable of realizing the function of preloading viscoelastic agent and a method for loading viscoelastic agent in the intraocular lens preloaded syringe. Background technique [0002] An intraocular lens (IOL) is an artificial lens that can be implanted in the eye to replace the natural lens in a person's eye that is clouded by cataract disease, or used in refractive surgery to correct the eye's vision. The shape of the intraocular lens usually consists of a circular optic and surrounding support haptics. [0003] Viscoelastic is a non-irritating, non-inflammatory high-elastic lubricating viscous agent with excellent biocompatibility and non-toxicity, and has been widely used in various ophthalmic operations. Viscoelastic agents play very important roles in filling, protecting, and lub...

AI Technical Summary

Problems solved by technology

However, those skilled in the art should be aware that this method of using a viscoelastic injector to inject viscoelastic into the intraocular lens implant cavity will lead to the following eight potential risks:

[0006] First, when the injection head of the viscoelastic agent is inserted into the viscoelastic injection port reserved for the IOL syringe, the metal injection head of the viscoelastic agent is easily scratched against the inner wall of the plastic injection port by misoperation, resulting in scratches and shatters. Endophthalmitis into the intraocular lens implant head cavity, as the intraocular lens is injected into the eye, the probability of postoperative complications of endophthalmitis increases

[0007] Second, when the injection head of the viscoelastic agent is inserted from the outlet of the intraocular lens implant head into the inner cavity of the intraocular lens implant head to inject the viscoelastic agent, if the operation is improper, the viscoelastic agent injection head will easily scratch the intraocular lens implant. The surface of the inner cavity of the head will cause the optical surface of the intraocular lens to be scratched during the injection and sliding process of the inner cavity of the implanted head, which will affect the optical imaging

[0008] Third, especially when the viscoelastic injection head is used to inject viscoelastic into the inner cavity of the intraocular lens implant, the intraocular lens has a potential risk of cross-infection

[0009] Fourth, the use of the viscoelastic agent should match the material of the IOL and the material of the implant head in order to achieve effective lubrication. Similarly, ophthalmic surgeons tend to confuse and misuse

[0012] Seventh, the operation steps and complexity are increased, so the chance of error will be higher

[0013] Eighth, the viscoelastic syringe is disposable, so the leftover viscoelastic and syringe used in the operation are thrown away, wasting resources and polluting the environment
