Centurion active fluidics enable high vacuum rates

AMSTERDAM — An early look at active fluidics and high vacuum rate of a new cataract removal system launched here showed no safety issues and a stable anterior chamber, according to a presenter.
“Traditional phaco uses gravity to drive the inflow of fluid into the eye. The Centurion Vision System (Alcon) uses active fluidics to proactively maintain the surgeon-set target IOP,” David Allen, FRCOphth, said at the European Society of Cataract and Refractive Surgeons meeting. Even though high vacuum rates are possible in traditional gravity systems, they are only achieved when bottle height is high, Allen said.

Allen presented data on 99 cases operated with the Centurion system. Thirty-three cases were done using a 2-mm incision, and all cases were done by two experienced surgeons. Target IOP in all cases was set at 81 mm Hg. One hemi-nucleus was consumed with maximum vacuum of 350 mm Hg, and the other with maximum vacuum at 600 mm Hg.
“We found there were no safety issues at all, and the anterior chamber was remarkably stable despite the use of 600 mm Hg vacuum and 2-mm incisions, Allen said.
