FAQ
Which chopper design is best for dense nuclei?
A sturdy sharp-tipped chopper with a design suited to horizontal or vertical chopping can improve control in dense nuclei. The best choice depends on the surgeon’s preferred technique.

What is the difference between choppers and prechoppers?
Choppers divide the nucleus during phacoemulsification. Prechoppers mechanically crack or divide the nucleus before or at the start of phacoemulsification, potentially reducing the need for ultrasonic energy.

Are left-handed versions available?
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.

Can these be used through micro-incisions?
Micro-incision versions are available for sub-1.50 mm incision sizes.

How should tips be inspected for wear?
Inspect the tip under magnification for dulling, bending, burrs, cracks, corrosion, or misalignment. Do not use an instrument with damaged or improperly closing jaws.
