Fluidics

The OS3 fluidics system with the TwinVac® Cassette and the integrated pressure sensor sets the standard. It makes possible switching within seconds between peristaltic and a real venturi pump during the operation.

Whichever vacuum or flow setting you work with, the anterior chamber remains stable at all times. In contrast to other machines, the OS3 has no tube systems with thin diameters or even filters. So the aspirated vacuum can display its full dynamic range at the tip of the opening. This results in better followability, excellent holdability of the lens fragments and easy vacuuming of thick lens material.

Overview of System Features

With the OS3 the possiblities are limitless. It facilitates the most up-to-date surgical techniques in cataract and vitreoretinal surgery:

• easyPhaco^®CO-MICS sub2mm coaxial MICS with the efficiency of the existing 2.8mm phaco

• easyPhaco^®2.2mm for 2.2 - 2.4mm incision, repulsion-free with unique chamber stability and magnetic force of attraction

• easyPhaco^®2.8mm for perfect emulsification of the hardest nuclei, without clogging
