Removable cap actuation for an intraocular lens cartridge

A method for delivery of an intraocular lens (IOL) into an eye, comprising:

• attaching an IOL cartridge to a handpiece, the IOL cartridge comprising:
• a housing comprising a compartment having an IOL disposed therein;
• a nozzle coupled to the housing and in fluid communication with the compartment;
• an actuator coupled to the housing and configured to translate along an exterior portion of the housing relative to the compartment from a first position to a second position;
• a first and a second set of internal ramps operably connected to the actuator;
• and
• a first and a second set of IOL manipulators inside the compartment;
• and
• translating the actuator from the first position to the second position to move the first and second set of internal ramps to actuate the first and the second set of IOL manipulators, respectively, to fold or straighten the IOL.

An intraocular lens (IOL) cartridge comprising:

• a housing;
• a slide disposed within the housing and comprising a first and a second set of internal manipulators;
• a compartment disposed within the housing and configured to receive an IOL, wherein an interior portion of the slide is exposed to the compartment;
• and
• a cap at least partially covering the slide, the cap configured to translate the slide to move the first and the second set of internal manipulators to fold or straighten the IOL upon removal of the cap.

• a nozzle coupled to the housing and in fluid communication with the compartment;
• an actuator coupled to the housing and configured to translate along an exterior portion of the housing relative to the compartment from a first position to a second position;
• and
• a first and a second set of internal ramps operably connected to the actuator,
• wherein as the actuator is translated from the first position to the second position, the first and the second set of internal ramps are configured to actuate a first and a second set of IOL manipulators, respectively, to manipulate the IOL for delivery, the first set of IOL manipulators comprising a pair of edge rollers pivotably attached to an interior portion of the IOL cartridge.
