Intraocular lens insertion devices and methods

摘要

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 2a of the intraocular lens 2 with respect to a distal end portion of the plunger 5.

主权项

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 as the removable cartridge is being attached to the insertion device main body; and maintaining the compression of the lens placement section after the removable cartridge has been attached to the insertion device main body.
