Abstract

An instrument to facilitate nuclear disassembly during cataract surgery includes a proximal handle, a shaft portion axially aligned with the proximal handle, an intermediate portion constructed to traverse the cortex of the eye, and a hook-form distal end. An inner region of the hook-form has a leading edge defined by diverging surfaces. The diverging surfaces lie at an acute splitting angle to one another selected to have a wedging effect when the leading edge is drawn along a cleavage plane of the nucleus. The diverging surfaces define a relatively bulky back portion that imparts desired stiffness to the leading edge. The hook-form is shaped to facilitate maintaining contact with the nucleus while the leading edge is drawn along the cleavage plane. A method of performing nuclear disassembly during cataract surgery utilizing the instrument is also described.
