Oscillating movement creates safer, more efficient phaco technique

SANTIAGO, Chile — The combination of standard ultrasound with oscillatory technology is an effective way to break up hard nuclei, and it significantly reduces the duration of phacoemulsification, ultrasound power and endothelial cell loss, according to a speaker at the Pan-American Congress of Ophthalmology.
Jorge Villar Kuri, MD, described a prospective, longitudinal, randomized study in which he and his colleagues compared oscillating technology to standard phaco in 60 eyes with very hard cataracts.
The first group of 30 patients underwent conventional phaco without oscillatory technology. Effective phaco time was approximately 1.65 seconds, compared with 1.39 seconds in the oscillating ultrasound group, Dr. Villar said.
Postop endothelial cell count in the conventional phaco group was 1,850, while in the oscillating ultrasound group the count was 2,010.
Using equipment with sonic oscillatory motion makes phaco shorter, more efficient and safer, Dr. Villar said.
