Scoop and chop - A modified phaco-chop technique for pseudoexfoliation and cataract

Phaco Chop: Pearls and Pitfalls

Since Kunihiro Nagahara’s original presentation at the 1993 ASCRS meeting, several different variations of chopping have evolved. Conceptually these can be divided into two main categories. I call the classic Nagahara technique horizontal chopping, because the instrument tips move toward each other in the horizontal plane during the chop. In vertical chopping, the two instrument tips move towar...

Phaco Chop Techniques: Comparing and Integrating Horizontal and Vertical Chopping

Paul Koch’s “Stop and Chop” method is a hybrid of divide-and-conquer and horizontal chopping. His technique begins with sculpting a traditional deep, central groove in order to crack the nucleus in half. One then stops the divide-and-conquer method, and chops the hemi-nuclei. Although the Koch method utilizes some horizontal chopping, this author coined the term “Non-stop Chop” to differentiate...

Comparison of divide and conquer and phaco-chop techniques during fluid-based phaco-emulsification.

PURPOSE To determine whether, similar to ultrasound phaco-emulsification, applied energy and surgery time decrease using phaco-chop nucleus fragmentation method compared to divide and conquer technique using the fluid-based system. METHODS This prospective, comparative, randomized clinical study included patients with cataract who were randomly assigned to use either standard divide and conqu...

Visco chop- a new technique for nucleus separation for soft cataracts in femtolaser assisted cataract surgery.

Chick feed technique versus standard chop technique in micro incision cataract surgery.

BACKGROUND The important factor for improving the cataract surgery is reduction in size of corneal incision. Small incision results in less induced astigmatism, and faster visual rehabilitation. METHODS An analysis of 100 eyes of 80 patients operated for phacoemulsification through micro incision by standard chop technique (50 eyes) in group-I, and chick feed technique (50 eyes) in group-II i...
