Ophthalmic device

A method of operating an ophthalmic device, the method comprising:

• gripping a housing of the ophthalmic device;
• applying a rotational force to a wheel of an activation assembly of the ophthalmic device;
• slidably moving one of a catheter, a wire and a tensioning device through a cannula of the ophthalmic device based on the rotational force;
• applying an inward orthogonal force to the wheel;
• moving the wheel and a moveable housing ring coupled to the wheel inward together towards an interior of the housing based on the inward orthogonal force;
• pumping fluid through a lumen of the cannula based on the inward movement of the coupled wheel and moveable housing ring;
• applying an outward orthogonal force to the coupled wheel and moveable housing ring;
• and
• drawing fluid from a reservoir based on the outward movement of the coupled wheel and moveable housing ring.
