Modular intraocular lens designs and methods

An extraction device for removing an intraocular lens (IOL) from an eye, comprising:

• a. a handle;
• b. a shaft extending distally from the handle, wherein at least a distal portion of the shaft is configured for insertion into the eye;
• c. a tongue extending distally from the distal portion of the shaft, the tongue configured for placement posterior to the IOL to protect eye anatomy;
• d. a grabber extending distally from the distal portion of the shaft, the grabber configured for placement anterior to the IOL, the grabber including a mechanism to grab the IOL;
• and
• e. a cutter extending distally from the distal portion of the shaft, the cutter having an extended position for cutting and a retracted position for no cutting.

A method of removing an intraocular lens (IOL) from an eye using an extraction device, comprising:

• a. inserting the extraction device into the eye, the extraction device including a handle, a shaft extending distally from the handle, a tongue extending distally from a distal portion of the shaft, a grabber extending distally from the distal portion of the shaft, and a cutter selectively extendable from the distal portion of the shaft;
• b. positioning the tongue posterior to the IOL to protect eye anatomy;
• c. grabbing the IOL with the grabber;
• d. pulling the IOL proximally with the grabber;
• e. cutting the IOL with the cutter as the IOL is pulled proximally;
• and
• f. removing at least a portion of the cut IOL from the eye.

An extraction device for removing an intraocular lens (IOL) from an eye, comprising:

• a. a handle;
• b. a shaft extending distally from the handle, wherein at least a distal portion of the shaft is configured for insertion into the eye;
• c. a tongue extending distally from the distal portion of the shaft;
• d. an IOL engaging member at the distal portion of the shaft for engaging the IOL, wherein the IOL engaging member is movable to an extended position by extending the IOL engaging member distally away from the distal portion of the shaft and anterior to the tongue, and also is movable to a retracted position by retracting the IOL engaging member proximally away from the extended position and at least partially into the distal portion of the shaft;
• and
• e. a cutter at the distal portion of the shaft, wherein the cutter is movable between an extended position for cutting and a retracted position for no cutting.
