What is chop technique?
Paul S. Koch, MD, described a hybrid technique called stop and chop, in which a deep groove is sculpted across the nucleus to divide it in half. Chopping is then performed in each of the two halves to further divide them.
What is surge in phaco?
Surge. Surge occurs during phacoemulsification when outflow exceeds inflow, and a sudden rush of fluid from the anterior chamber occurs post-occlusion. When the tip of the phaco needle is occluded, flow is instantly interrupted and negative pressure builds within the tubing.
What is vertical chop?
In vertical chopping, the two instrument tips move toward each other in the vertical plane in order to create the fracture. Although David Dillman, MD, later popularized the name “phaco quick chop,” the “phaco snap and split” technique, developed by Hideharu Fukasaku, MD, was the first incarnation of this concept.
What is the meaning of phaco?
Phacoemulsification, or phaco, is method of cataract surgery in which the eye’s internal lens is emulsified using ultrasonic energy and replaced with an intraocular lens implant, or IOL.
Which is better phaco or mics?
Whereas Micro-incision cataract surgery (MICS) has been considered to be a less traumatic surgery that provides better results than the small incision phacoemulsification. The long-term stability of these outcomes and surgical capacity makes MICS the most adequate and correct modern approach to cataract surgery.
What is stop-and-chop surgery?
The surgeon behind Stop-and-Chop is Paul Koch MD from Rhode Island, USA who coined both the term and the technique in 1994. The idea is to make a central groove in the nucleus and crack it into two hemi-sections, then instead of proceeding to more grooving as with the divide-and-conquer technique, you “stop and chop” the nuclear halves.
How can i Improve my phaco power?
Continue technique, back on material with needle, varying on foot position 3 and back to 2 frequently with a tapping or you can use a pulse mode or burst mode to get little bursts of phaco power that allows better control and not add too much energy to the eye.
What is stop and chop nuclear cracking?
The idea is to make a central groove in the nucleus and crack it into two hemi-sections, then instead of proceeding to more grooving as with the divide-and-conquer technique, you “stop and chop” the nuclear halves. “The procedure begins as a routine nuclear cracking technique and then stops.
What is stop-and-chop for nucleus removal?
The Stop-and-Chop technique for nucleus removal during cataract surgery blends aspects of the Divide-and-Conquer method with some Phaco Chop. Some surgeons use it as a stepping stone before moving to full chop techniques.
