Ophthalmic choppers and prechoppers are essential for controlled division of the cloudy nucleus during cataract surgery. Eye choppers are also used for stabilizing the eye, manipulating tissues, guiding the intraocular lens (IOL), and protecting the delicate posterior capsule during phacoemulsification, ensuring precision and preventing damage. RUMEX offers offers varied tips and designs for specific techniques such as quick choppers, cross choppers, Seibel, Nagahara choppers, and etc.

| Which chopper is best for horizontal chopping? A horizontal chopper with an appropriately angled, sharp tip is recommended. The exact profile depends on surgeon preference. Which design is preferred for vertical chopping? A vertical chopper or phaco chopper with a sharp downward cutting edge is generally used for vertical chop techniques. How do prechoppers differ from standard choppers? Prechoppers mechanically divide the nucleus before significant phaco energy is applied; standard choppers divide the nucleus during phacoemulsification. What incision size is required? The required incision depends on the shaft diameter and instrument design. Use the manufacturer’s stated minimum incision size. Are instruments available for left-handed surgeons? Left- and right-handed versions are available, particularly for angled instruments. RHD models are designed for a Right Hand Dominant Doctor, the chopper is to be held in the non-dominant (left) hand during the surgery. LHD models are for a Left Hand Dominant Doctor, the chopper is to be held in the non-dominant (right) hand during the surgery. How should tip wear or misalignment be assessed? Inspect under magnification for dullness, bending, cracks, burrs, corrosion, damaged coatings, or any loss of proper alignment. |
