Abstract
Intraocular lens loading devices and methods of use. In some embodiment the devices are used to sequentially splay first and second haptics while loading the intraocular lens into a delivery lumen.
Claims49
A method of reconfiguring an intraocular lens for delivery, comprising
- providing an intraocular lens in an intraocular lens receiving region of a base member such that a leading haptic is in a substantially at-rest configuration relative to an optic portion of the intraocular lens;
- and
- moving a free end of the leading haptic away from the optic portion and towards a delivery lumen with an actuatable splaying member.
A method of splaying leading and trailing haptics of an intraocular lens in preparation for delivery into an eye, comprising
- splaying a leading haptic relative to an optic portion of an intraocular lens with an actuatable splaying member;
- and
- splaying a trailing haptic relative to the optic portion, wherein splaying the leading haptic is initiated prior to initiating the splaying of the second haptic.
A method of splaying leading and trailing haptics of an intraocular lens in preparation for delivery into an eye, comprising actively splaying a leading haptic and passively splaying a trailing haptic.
A method of positioning an intraocular lens in a base carrier, comprising:
- positioning an intraocular lens in an intraocular lens receiving region in a base member such that a leading haptic free end is closer to a first side of a base member channel and is accessible for direct actuation in a proximal direction.
A device for reconfiguring an intraocular lens in preparation for delivering the intraocular lens into an eye, comprising
- a base member comprising an intraocular lens receiving region;
- a splaying member adapted to interact with the base member to engage and splay a leading haptic of an intraocular lens positioned in the lens receiving region;
- a loading member adapted to interact with the base member to engage the intraocular lens after the leading haptic has been splayed and to advance the intraocular lens towards a delivery lumen.
