Katena Instrument Wipes are sterile, disposable sponges designed for cleaning delicate instrument tips during microsurgical procedures. Each pouch contains one wipe and one corneal shield. When moistened, the non-shedding sponge becomes smooth, soft, and pliable for gentle use. A free Corneal Light Shield is included with each wipe. When placed on the cornea, the shield helps protect the retina from harmful light exposure.
