Problems solved by technology

However, this product does not fully consider the influence of the viscoelastic agent flow on the state change of the anterior support loop when the viscoelastic is injected, and there is a problem that the front support loop is unstable during the injection process, and the reliability needs to be improved.

Abstract

The invention provides a preassembled intraocular lens implantation device capable of improving the action reliability of a front support loop of an intraocular lens. A pin hole (201) is formed in theintraocular lens implanter (1); the pin hole (201) is positioned between the optical part (6) of the intraocular lens (5) and the front end part (7a2) of the front support loop (7a) in the front-backdirection; the limiting seat is provided with a limiting pin (42); the limiting pin is inserted into the implantation head (2) through the pin hole and is positioned between the optical part (6) of the intraocular lens (5) and the front end part (7a2) of the front support loop (7a); the front surface, facing the front end (7a2) of the front supporting loop (7a), of the limiting pin (42) is provided with a guiding face (42b), and the guiding face (42b) is composed of an inclined face obliquely extending towards the rear upper portion.

Description

technical field [0001] The invention relates to a preinstalled artificial lens implantation device. Background technique [0002] An intraocular lens is a type of artificial lens, and in cataract surgery, the technique of implanting an intraocular lens to replace the natural intraocular lens in a person's eye clouded by cataract disease has been widely practiced. [0003] The shape of an intraocular lens usually consists of a central circular optic and peripheral haptics. According to the material of the processed intraocular lens, the intraocular lens can be divided into hard intraocular lens and soft intraocular lens. Due to the non-foldability of the material of the rigid intraocular lens, the implantation of the intraocular lens can only be performed by making a surgical incision on the cornea that is roughly the same in diameter and width as the optical part of the lens. The soft intraocular lens is foldable because of its soft material. A small surgical incision (gen...
