Abstract
Official abstract text for this publication.
There is provided an intraocular lens insertion device capable of easily positioning a circumference of an optical portion of an intraocular lens with respect to a distal end of a plunger. An intraocular lens insertion device 1 comprises: a cartridge 3 having a lens placement section 16 in which an intraocular lens 2 is to be placed; an insertion device main body 4 having a plunger 5 for pushing out the intraocular lens 2 with the cartridge 3 being attached to the insertion device main body 4 ; and a deforming means 6 for deforming the lens placement section 16 . A slit 21 is formed on the lens placement section 16 , and the deforming means 6 deforms the lens placement section 16 in a diameter-decreasing direction thereof when attaching the cartridge 3 to the insertion device main body 4 . In this way, the intraocular lens 2 is settled at a predetermined position in the lens placement section 16 , thus making it possible to position a circumference of an optical portion 2 a of the intraocular lens 2 with respect to a distal end portion of the plunger 5.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of positioning an intraocular lens that has been placed within a lens placement section of a removable cartridge, the lens placement section including an inner surface, the method comprising the steps of: compressing the lens placement section of the removable cartridge with a portion of an insertion device main body such that portions of the lens placement section inner surface are moved closer to one another by the insertion device main body…
