Claim 10:
11. A Bernoulli gripper for intraocular lenses, the Bernoulli gripper comprising:
a gripper body with a cavity corresponding in shape to an optic zone of an intraocular lens;
a first channel formed within the gripper body, the first channel penetrating the cavity at a first end of the first channel;
a mechanical stop enabled to detain a haptic of the intraocular lens to prevent rotation of the intraocular lens; and
a second channel formed within the gripper body, the second channel penetrating the gripper body at a first end of the second channel and penetrating the mechanical stop at second end of the second channel;
wherein:
the first channel is enabled to supply a first fluid medium to the cavity at a first velocity such that the intraocular lens positioned with the optic zone in proximity to the cavity is subject to a first pressure force against the cavity by a Bernoulli effect; and
the second channel is enabled to subject at least a portion of the intraocular lens positioned in proximity to the second channel to a second pressure force, wherein the second pressure force is applied to the haptic when the haptic is detained by the mechanical stop, and wherein the second pressure force comprises underpressure.
