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...

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...
متن کاملPhaco 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...

Interval-based temporal logics are a natural framework for modeling a number of problems from various areas of computer science such as artificial intelligence, natural language processing, temporal databases and formal specification. Some interval-based temporal logics became popular in recent years, such as Venema’s CDT logic, Halpern and Shoham’s HS logic, Moszkowski’s ITL and its propositio...
