Abstract
An insertion tool for an intraocular lens including a disposable insertion assembly and a reusable handle. The insertion assembly includes a rigid tube with a collar about its proximal end and a lens holder which slides within the rigid tube and also includes a collar on its proximal end and a paddle on its distal end. The handle includes a hollow barrel connected to the rigid tube collar and a driver barrel inside the barrel connected to the collar of the lens holder. An actuator button slides along the outside of the barrel and extends through a slot in the side of the barrel to engage the drive barrel. A pusher rod may be placed inside the bore of the drive barrel to help hold the lens in position.
