Surgical scissors designed to cut eye tissues during ophthalmic procedures. These scissors are typically handheld, manual instruments with two metallic (e.g., stainless steel) blades with sharp or blunt tips that slide past each other (i.e., shearing action). The blades are usually attached to handles with the proximal end conformed as a ring to facilitate holding and operating with the fingers; both parts are joined by a swivel pin in the center. Small, fine scissors with serrated flat or curved handles to provide a safer grip and inserted flat springs to avoid uneven tension and provide a more uniform and/or sensitive manipulation are also available. Dedicated scissors with a variety of tips and blades are available to cut the iris, sclera, cornea, lens capsule, and other eye tissues during eye surgery procedures (e.g., capsulotomy, sclerotomy, tenotomy).
