The Mackool Phaco Chopper/Spatula is a double-ended ophthalmic tool used for effective manipulation of the lens nucleus during cataract surgery. Its micro ball-shaped chopper at one end has an interior cutting edge that is angled 10 mm from bend to tip, allowing for precise nucleus segmentation, and its cylindrical spatula at the other end has a 0.4 mm blade that is angled and semi-vaulted 11 mm from bend to tip, allowing for controlled nucleus rotation and stabilization. The instrument's overall length ranges from 114 to 138 mm, and it is made of stainless steel, titanium, or Diamatrix's Signature Feather-Series round handle.
