Patent number: 10405972Abstract: 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.Type: GrantFiled: August 16, 2016Date of Patent: September 10, 2019Assignee: Novartis AGInventors: Asif Fayyaz, Jian Liu, Sudarshan B.
