To present a new device designed to chop smoothly the hardest cataract during the phacoemulsification process, using both, rotational as well as reverse directional chop using a newly designed chopper termed the "Scythe"
Mehta International Eye Institute.
Clear Corneal tunnels using a 2.8 mm diamond knife. A good rhexis. Adequate hydrodissection. The Scythe is a small curved chopper designed to be twirled at the end of its holder, with the inner blades and tips very sharp but with the shaft of the chopper flattening at the periphery. It is introduced from the side port, twirled to enter the lens at the level of the impacted tip. Upon entry it is simply pulled which automatically induces a crack. The lens is rotated, and then "scythed" again.
The advantage of the newly devised Scythe phaco chopper is that the crack develops right next to the tip of the phaco, can be embedded easily, and is a very fast and controlled technique, even in the hardest lens. It effectively uses twin vectors of force. Ideal for splitting a recalcitrant cataract and phaco in small stenotic pupils.
New instrument works very effevtively and is an ideal chopper for phaco.
