Micro-Mechanical Nucleus Division & Chamber Control
Efficient phacoemulsification relies heavily on clean nuclear division to reduce total ultrasound energy, minimize thermal energy delivery to clear corneal incisions, and protect the corneal endothelium. Choppers and nucleus manipulators must offer precise tip geometry, perfect balance, and ultra-smooth or sharp splitting edges to divide dense nuclei safely without placing stress on the zonular apparatus.
Manufactured in strict adherence to ISO 13485 and CE quality standards, our Choppers & Nucleus Instruments collection is built from premium Medical Stainless Steel and Titanium Alloy. Featuring ergonomic, lightweight handles, non-glare matte finishes, and hand-finished working tips, these instruments enable surgeons to execute horizontal chopping, vertical chopping, pre-chopping, and nucleus rotation with maximum tactile responsiveness and minimal intraocular strain.
Key Models & Surgical Applications
-
Phaco Choppers & Cleavers: Specifically angled and honed blades engineered for horizontal and vertical nuclear chopping in micro-incision cataract surgery ($1.8\text{ mm}$ to $2.8\text{ mm}$). Includes gold-standard patterns like the Nagahara Chopper (horizontal chop), Rosen Chopper, Universal Chopper, and heavy-density Kansas Nucleus Cleavers.
-
Pre-Choppers & Division Tools: Designed for manual pre-chopping of the nucleus before applying phaco energy, reducing overall ultrasound time, featuring specialized Pre-Choppers and the Kansas Trisector.
-
Sustainers & Manipulators: Dual-function and specialized manipulating tips engineered for safe nuclear rotation, fragment elevation, and capsular bag stabilization, featuring Nucleus Sustainers and the Lieberman Nucleus Manipulator.
Why Choose Our Nucleus Instruments?
-
