Disposable Crescent Knife

Disposable Crescent Knife is a specialized ophthalmic surgical instrument used for creating corneal and scleral tunnels, performing lamellar dissections, and preparing surgical entry pathways during cataract and anterior segment procedures.

The instrument features a crescent-shaped microsurgical blade designed to facilitate smooth tissue separation and controlled partial-thickness dissection. Its curved blade geometry enables surgeons to create precise tunnel architecture while maintaining excellent depth control throughout the procedure.

Manufactured as a single-use sterile instrument, the Disposable Crescent Knife eliminates the need for cleaning, sharpening, maintenance, and reprocessing. This design helps ensure consistent blade sharpness and readiness for every procedure.

The ultra-sharp cutting edge promotes clean tissue dissection with minimal resistance, supporting accurate scleral tunnel creation, corneal tunnel formation, and lamellar tissue preparation. The crescent profile facilitates controlled advancement through tissue planes while preserving surrounding structures.

Disposable Crescent Knives are commonly utilized during phacoemulsification cataract surgery, manual small-incision cataract surgery (MSICS), corneal tunnel construction, scleral tunnel development, self-sealing wound creation, and other anterior segment microsurgical procedures.

The lightweight ergonomic handle provides excellent balance and control, enabling precise manipulation under operating microscope magnification. The instrument is designed to support smooth surgical movements and predictable incision quality.

Manufactured from premium surgical-grade materials, the instrument delivers reliable sharpness, precision, and structural stability throughout the procedure. Sterile packaging helps support efficient operating room workflow and immediate clinical use.

Available in multiple blade widths, blade lengths, tip profiles, and handle designs, Disposable Crescent Knives can be selected according to surgeon preference and procedural requirements.

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