INTRAOCULAR LENS INJECTOR AND INTRAOCULAR LENS INJECTION DEVICE

摘要

An intraocular lens injector (1) includes: a hollow body having an injector body (5) provided with a lens placement portion (11) on which an intraocular lens is placed, and a screw member (8) with a first threaded portion (8b) formed thereon and connected to a rear end portion of the injector body (5), and rotatable around an axis of the injector body (5) without moving in an axial direction of the injector body; and a moving member (9, 10) having a second threaded portion (9c) that engages with the first threaded portion (8b) from an initial state before use, and configured to release the intraocular lens from a tip of an injection tube 7 by moving in an axial direction of the injector body (5) independently from the screw member (8) due to an engagement of the first threaded portion (8b) and the second threaded portion (9c), during a rotating operation of the screw member (8).
