Haptic optic management system utilizing rotating cams
Systems, methods, and devices for inserting an intraocular lens (IOL) into an eye may be provided. An example haptic optic management system may comprise a first cam assembly comprising a first cam body portion, an opening in the first cam body portion, and haptic folder arms disposed in the opening. The haptic optic management system may further comprise a second cam assembly positioned on one side of the first cam assembly, wherein the second cam assembly comprises a second cam body portion, an opening in the second cam body portion, and optic folders disposed in the opening. The haptic optic management system may further comprise a central plate for holding an intraocular lens in the opening of the second cam body portion, wherein the central plate is disposed between the first cam assembly and the second cam assembly.
1 . An intraocular lens (IOL) insertion tool, comprising:
an IOL disposed within a cavity;
a nozzle;
a plunger configured to advance the IOL through the nozzle; and
a haptic optic management system (HOMS) comprising:
one or more arms;
a cam mechanism configured to translate a user actuation of the HOMS to actively
deform the IOL before the IOL is advanced into the nozzle,
wherein the HOMS is further configured to tuck one or more haptics of the IOL onto an optic of the IOL and to fold one or more edges of the optic of the IOL over the one or more tucked haptics of the IOL; and
wherein the HOMS comprises a rotatable dial, the user actuation comprises rotating the dial, and the cam mechanism is configured to translate rotation of the dial to move the one or more arms disposed within the cavity, thereby actively deforming the IOL.
2 . The IOL insertion tool of claim 1 , wherein the cam mechanism of the HOMS is further configured to translate the user actuation of the HOMS to actively deform the IOL without the IOL making contact with the nozzle or the plunger.
3 . The IOL insertion tool of claim 1 , wherein the HOMS is further configured to elongate, in opposite directions, a pair of haptics of the IOL.
4 . The IOL insertion tool of claim 3 , wherein the HOMS is further configured to compress the pair of haptics when the pair of haptics are elongated.
