Eye (ophthalmic) surgery scissors designed to cut corneal and/or scleral tissues during ophthalmic surgical procedures. These scissors are typically small handheld, manual instruments with two metallic (e.g., stainless steel) straight or curved blades (frequently beveled) and sharp or blunt tips that slide past each other (i.e., shearing action). The blades are attached to handles with the proximal end conformed as a ring to facilitate holding and operating with the fingers and are joined by a swivel pin in the center; some corneal scissors are flat and include wider rings (e.g., ribbon style). Scissors with serrated flat handles with inserted flat springs to provide a safer grip and provide a more uniform and/or sensitive manipulation and avoid uneven tension are also available; they may be used in microsurgical procedures. Corneoscleral eye surgery scissors are used in keratoplasty, corneal transplant, corneal section, and other ophthalmic procedures involving the cornea and/or the sclera.
