Abstract:
A device for single-handed insertion of an intraocular lens into a patient's eye, having a barrel, a finger flange attached to the barrel, a plunger slidingly engaged with the barrel, a ring attached to the plunger, a projection extending from the plunger, along its length, for resisting bending in the plunger and transmission of torsion through the plunger and for assisting in preventing rotation of the plunger relative to the barrel, and a channel formed lengthwise along the interior of the barrel that engages the projection of the plunger. An alternative embodiment of the invention has a walled chamber, for receiving the lens, that forms an aperture to allow a trailing haptic of the lens to temporarily protrude outside the device. This embodiment can also include a rod for moving the lens through the chamber, with either the rod or the chamber having at least one groove along its length to allow the transmission of fluid through the device, away from the patient's eye, and for receiving the trailing haptic as the haptic is drawn from outside the device, through the aperture and into the chamber. The device is particularly adapted for insertion of acrylic-type lenses.
