Corneal Tunnel Crescent Knife

Corneal Tunnel Crescent Knife is a specialized ophthalmic surgical instrument used to create precise corneal and scleral tunnel incisions during cataract surgery and other anterior segment procedures.

The instrument features a crescent-shaped blade geometry specifically designed for controlled lamellar dissection and tunnel formation. This unique blade profile allows surgeons to create uniform partial-thickness dissections while maintaining excellent depth control throughout the procedure.

Corneal Tunnel Crescent Knives are widely utilized in cataract surgery techniques that require the creation of self-sealing corneal or scleral tunnels. The blade’s curved design facilitates smooth advancement through tissue planes while reducing resistance and promoting controlled incision architecture.

The ultra-sharp cutting edge enables clean tissue separation with minimal disruption to surrounding structures. Precise tunnel construction contributes to wound stability and helps support effective postoperative healing.

These knives are commonly employed in phacoemulsification cataract surgery, manual small-incision cataract surgery (MSICS), scleral tunnel formation, corneal tunnel creation, and other anterior segment microsurgical procedures. Crescent knives are specifically recognized for making sclerocorneal tunnels in cataract surgery.

The slim blade profile provides excellent visibility under the operating microscope, allowing surgeons to maintain precise control throughout delicate ophthalmic procedures.

Manufactured from premium surgical-grade materials, the instrument delivers consistent sharpness, durability, and dependable cutting performance. Various blade widths, tip configurations, and handle styles are available to accommodate different surgical techniques and surgeon preferences.

Widely used in hospitals, ophthalmic surgery centers, eye clinics, and ambulatory surgical facilities, the Corneal Tunnel Crescent Knife remains an essential instrument in modern cataract and anterior segment surgery.
