Corneal Tunnel Crescent Knife is a precision ophthalmic microsurgical knife designed for creating corneal and scleral tunnel incisions during cataract and anterior segment surgery. Featuring a crescent-shaped ultra-sharp blade, controlled lamellar dissection capability, and ergonomic handling design, this instrument enables precise tunnel formation, smooth tissue separation, and consistent surgical performance. Crescent knives are commonly used for scleral tunnel and self-sealing incision creation in cataract procedures.
