Micro Crescent Knife

Micro Crescent Knife is a specialized ophthalmic surgical instrument used for highly precise tissue dissection and tunnel formation during cataract surgery, corneal surgery, and anterior segment microsurgical procedures.

The instrument features a miniaturized crescent-shaped blade engineered for controlled lamellar dissection in delicate ocular tissues. Its compact blade profile allows surgeons to perform precise dissections within confined surgical spaces while maintaining excellent visualization and depth control under operating microscope magnification.

The ultra-sharp cutting edge facilitates smooth tissue separation with minimal resistance, enabling the creation of precise corneal and scleral tunnels, partial-thickness dissections, and microsurgical entry pathways. The reduced blade dimensions support meticulous surgical technique and enhanced maneuverability.

Micro Crescent Knives are commonly utilized during phacoemulsification cataract surgery, manual small-incision cataract surgery (MSICS), corneal tunnel creation, scleral tunnel formation, lamellar corneal procedures, wound architecture development, and other anterior segment interventions requiring high levels of precision.

The slim microsurgical design promotes excellent visibility and controlled blade advancement through tissue planes. The compact blade geometry allows surgeons to perform fine dissections while minimizing disruption to surrounding ocular structures.

The ergonomic precision handle provides outstanding balance, tactile feedback, and instrument control, helping surgeons execute delicate microsurgical movements with confidence and accuracy.

Manufactured from premium surgical-grade stainless steel and high-performance microsurgical materials, the instrument offers exceptional sharpness, durability, corrosion resistance, and reliable long-term performance.

Available in multiple blade widths, blade lengths, tip profiles, and handle configurations, Micro Crescent Knives can be selected according to surgical technique and surgeon preference.

Widely used in hospitals, ophthalmic surgery centers, corneal specialty clinics, eye hospitals, and ambulatory surgical facilities, the Micro Crescent Knife is an essential instrument in advanced ophthalmic microsurgery.

Depending on the model, the instrument may be available in reusable or sterile disposable configurations.
