Devices and methods for lens delivery

A system for delivering an intraocular lens (IOL) to a patient's eye, the system comprising:

• a modular cartridge containing the IOL;
• and
• a lens delivery device configured to receive the modular cartridge, the lens delivery device comprising:
• a body comprising a channel therethrough;
• a first interference portion located within the channel;
• and
• a plunger configured to receive a user-supplied force to move the plunger axially through the channel of the body, comprising:
• a second interference portion, located along a first length of the plunger, configured to interact with the first interference during the axial movement of the plunger to form a damping mechanism to maintain a specified resistance to the user-supplied force, wherein the axial movement of the plunger is configured to drive the IOL through the modular cartridge coupled to the body, delivering the lens from the lens delivery device.
