<P>PROBLEM TO BE SOLVED: To provide an intraocular lens injection instrument capable of suitably positioning an intraocular lens without taking time or labor when sending the intraocular lens into an eye and opening it by using the intraocular lens injection instrument. <P>SOLUTION: The intraocular lens injection instrument includes: an injection tubular part having a path wherein the space that an intraocular lens passes through is gradually smaller as approaching the front end for folding the intraocular lens; a lens holding part for mounting the intraocular lens on the proximal end of the injection tubular part; and a plunger provided so as to be moved forward and backward in an axial direction inside the tube of an injection instrument body for pushing the intraocular lens out of the injection tubular part. In the intraocular lens injection instrument, a gap that a rear support part can pass through along the periphery of the front end is formed between the front end of the plunger and the front end opening of the injection tubular part in order to release the rear support part of the intraocular lens which behaves on the basis of the opening operation of the intraocular lens sent from the front end of the injection tubular part along the periphery of the front end of the plunger. <P>COPYRIGHT: (C)2011,JPO&INPIT |
