Chang Phaco Chopper

Chang Phaco Chopper is a specialized ophthalmic surgical instrument used during phacoemulsification cataract surgery to facilitate controlled fragmentation and disassembly of the crystalline lens nucleus.

Designed for advanced cataract surgery techniques, the instrument features a curved micro-finger style chopping tip with a defined inner cutting edge, enabling surgeons to engage the lens nucleus and create controlled cleavage planes during nucleus fragmentation procedures. This design is particularly suited for horizontal chopping techniques and precise nuclear segmentation.

The instrument works in conjunction with the phacoemulsification handpiece to mechanically divide the nucleus into smaller fragments that can be emulsified and aspirated more efficiently. Controlled fragmentation helps improve surgical efficiency and facilitates cataract removal through small-incision techniques.

The curved tip geometry allows surgeons to maneuver around the nuclear equator while maintaining precise control during chopping procedures. The defined inner edge assists in creating accurate fracture lines and controlled separation of nuclear material.

Its slim low-profile shaft provides smooth insertion through small corneal incisions and excellent visualization under the operating microscope. The streamlined design supports delicate intraocular maneuvers while minimizing obstruction within the surgical field.

The ergonomic handle offers superior balance, tactile feedback, and maneuverability, allowing surgeons to perform advanced chopping techniques with confidence and precision.

Chang Phaco Choppers are commonly used during phacoemulsification cataract surgery, horizontal chop techniques, nucleus fragmentation, lens disassembly, dense cataract management, and advanced anterior segment procedures.

Manufactured from premium surgical-grade stainless steel, the instrument offers exceptional durability, corrosion resistance, and dependable long-term performance. The satin or matte low-glare finish minimizes reflections under microscope illumination and ophthalmic surgical lighting.

Available in multiple tip profiles, shaft lengths, angles, and handle configurations, Chang Phaco Choppers can be selected according to surgeon preference and surgical technique.

Widely used in hospitals, ophthalmic surgery centers, eye clinics, and ambulatory surgical facilities, the Chang Phaco Chopper is an essential component of modern cataract surgery instrument sets.

Fully reusable and autoclavable, the instrument is designed to withstand repeated cleaning and sterilization cycles while maintaining tip precision, alignment, and structural integrity.
