    Phaco with novel system yields excellent cutting efficiency, chamber stability

    Mid-range device decreases surge, improves fluidics control in streamlined design

    Take-home message: A new phacoemulsification system offers surgical functionality, features, and technology in a compact form factor.

    Bakersfield, CA—A novel phacoemulsification system (Compact Intuitiv, Abbott Medical Optics [AMO]) offers state-of-the-art fluidics and phacoemulsification technology and could fill a niche as an upgrade for users who prefer the value of a mid-level system to the expense of a high-end system.

    “[The manufacturer] has taken a multi-pronged approach to cataract surgery, allowing surgeons to decide what system suits their surgical and operational needs instead of just having one cataract system for everyone,” said Daniel H. Chang, MD, Empire Eye and Laser Center, Bakersfield, CA, who has experience with the new device.

    The small (about the size of a briefcase) and lightweight system is reminiscent of a previous-generation phacoemulsification system (Sovereign Compact, AMO), but it incorporates much of the phacoemulsification and fluidics technology of the company’s flagship line (Whitestar Signature, AMO), Dr. Chang explained.

    Fluidics, technology

    The new system has the peristaltic fluidics of the Signature system as well its energy modulation feature (Ellips FX handpiece, AMO). The tip of the handpiece moves both longitudinally and transversally, so the combined movements produce an elliptical pattern. The elliptical pattern improves cutting efficiency since the entire circumference of the tip is in motion—not just the off-axis portion, as in torsional phacoemulsification. This can help to ease nuclear removal and to reduce phacoemulsification time.

    The tip cuts smoothly on both hard and soft lenses and also minimizes heat from strain forces because the stress on the phacoemulsification needle during ultrasound generation is concentrated at the hub rather than distributed along the entire shaft, as in torsional ultrasound.
