Provided is a surface treatment method for a surgical implant that improves fatigue strength of the surgical implant while maintaining the microscopic surface structure of the surgical implant. A surface treatment method for a surgical implant, including: placing an additive manufactured surgical implant in a processing liquid, the surgical implant including a microscopic surface structure having a complete penetration area and an incomplete penetration area; and causing a nozzle immersed in the processing liquid to eject a cavitation jet of the processing liquid to the surgical implant to remove the incomplete penetration area remaining on a surface of the surgical implant and apply a compressive residual stress to the surface of the surgical implant.

A device for manipulating an orthopedic implant includes a base graspable by a user, a bending assembly including a pin having an outer surface extending between a first end of the pin that is coupled to the base and an opposing second end of the pin, and a gripper coupled to the outer surface of the pin and including a jaw, and a slider coupled to the bending assembly and slidable relative to the bending assembly to shift the jaw of the gripper between a flexed state for gripping an orthopedic implant and an unflexed state for releasing the orthopedic implant.

An apparatus for eye surgery may include an implant support, a folding arm (330), an edge roller (335), and a dial (320). Some embodiments of the implant support may include an implant bay, a tab rail, a tab slot, and a pawl. The folding arm may be coupled to the implant support and may include a dial pin. The edge roller may be coupled to the implant support and may include a roller track. Some embodiments of the dial may include an arm track, a roller pin, a plurality of ratchet teeth, and a tab. The dial can be configured to be rotated relative to the implant support so that the ratchet teeth rotate relative to the pawl, the dial pin travels the arm track and causes the folding arm to rotate, and the roller pin then travels the roller track to cause the edge roller to rotate.
