Which of the following instruments is specifically designed for precision cutting in ophthalmic surgery?

Strabismus scissors are specifically designed for precision cutting in ophthalmic surgery. Their design features long, narrow blades that allow for intricate maneuvers in the delicate tissues of the eye. The blades often have a slight curve and may include a beveled edge to provide greater control and accuracy when making incisions around the ocular area. This precision is critical in ophthalmic procedures, where even minor variations can significantly impact the outcome.

Other instruments listed, such as the Derf needle holder, Young’s tongue forceps, and Negus forceps, serve different purposes within surgical settings. While they are valuable for their specific functions, they do not possess the tailored design required for precision cutting necessary in ophthalmic surgery.
