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.

Systems and methods for intra-ocular lens advancement

An intraocular lens (IOL) insertion apparatus may include a hand piece body having a distal tip, an IOL folding chamber, and IOL a dwell position, and a telescoping plunger having a first plunger portion and a second plunger portion. The first plunger portion and second plunger portion may be arranged to simultaneously advance through a first portion of a displacement of the telescoping plunger, and one of the first and second plunger portions may be arranged to advance through a second portion of the displacement of the telescoping plunger.

IOL delivery systems

An intraocular lens (IOL) insertion apparatus may include a handpiece body having a distal tip and a deployment chamber located at a distal end of the handpiece body. The deployment chamber is sized and shaped to hold a folded IOL. The IOL insertion apparatus further includes a deployment system disposed within the handpiece body. The deployment system may include a deployment carriage movable between a first position and a second position within the handpiece body. The deployment carriage may include a biasing element that biases the deployment carriage in a distal direction toward the distal tip. The deployment system may further include a deployment trigger that prevents distal movement of the deployment carriage unless pressed and a deployment plunger having a proximal end secured to the deployment carriage and a distal end to engage the folded IOL.

Systems and methods for intraocular lens deployment

Intraocular lens (IOL) insertion apparatus and methods of use are provided and described herein. An example IOL insertion apparatus may include a handpiece body having a distal tip, a deployment chamber having an opening at a distal end of the handpiece body, and a deployment system disposed within the handpiece body. The deployment system can include a deployment carriage movable between proximal and distal positions within the handpiece body and a deployment plunger with a proximal end secured to the deployment carriage and a distal end to engage a folded IOL. The insertion apparatus may further include a damping feature protruding from a wall of the deployment chamber or a portion of the deployment system. The first damping feature may be positioned and arranged to increase a resistance to movement of the deployment system along a portion of a path traveled thereby between the proximal and distal positions.
