Abstract: An intraocular lens (IOL) insertion apparatus includes a handpiece body having a distal tip and a proximal section. The IOL insertion apparatus also includes a folding chamber located within the handpiece body, the folding chamber shaped to fold an IOL advancing through the folding chamber. The IOL insertion apparatus also includes an advancement system. The advancement system includes an advancement carriage movable between a first position and a second position within the handpiece body. The advancement carriage includes a spring system biasing the advancement carriage in a distal direction toward the second position and a dampening system to dampen motion of the advancement carriage. The advancement system further includes an elongated advancement plunger that includes a distal end to advance the IOL through the folding chamber and a proximal end connected to the advancement carriage.
