Abstract Details

Purpose:

Here we describe a new chop technique that is valuable for two groups of ophthalmologists: 1) experienced surgeons dense cataracts or zonulopathies, and 2) inexperienced surgeons who desire to learn a chop technique. We have termed this new method “rotary chop” since the partial thickness pilot holes created by the phacoemulsification tip produce a rotary phone dial appearance.

Setting:

Two sites, multinational, academic centers

Methods:

After hydrodissection, the phaco tip is introduced inside the eye, angled steeply posterior in the periphery of the nucleus. The phaco tip is burrowed into the nucleus. Then remove the tip from the nucleus. Rotate cataract 180 degrees so that the initial pilot hole is 180 degrees across from the main wound. Again, angle the phaco tip steeply posteriorly. Burrow into the nucleus. Continue to hold vacuum as in a normal chop. Place chopper into the original pilot hole. Bring chopper and phaco tip together to initiate a crack. Use instruments to pull the two hemi-nuclei apart, propagating the crack.

Results:

This new rotary chop technique is favorable for multiple reasons. First, it easily lends itself to the teaching of chop techniques. Whether your ultimate goal is to master horizontal chop or vertical chop, rotary chop is a stepping stone to all chopping techniques.

Conclusions:

In summary, we describe a new technique coined “rotary chop” that facilitates learning of the chop technique and also allows for easier disassembly of mature or complex cataracts.
