Initial Clinical Experience With a New Phaco Handpiece for Lens Fragment Removal in Femtosecond Laser–Assisted Cataract Surgery Without Ultrasound
To evaluate the effectiveness of a new Phaco handpiece without ultrasound for lens fragment aspiration in microincision femtocataract surgery.
The new Zero Phaco I/A handpiece (Bausch + Lomb) is a disposable handpiece designed for use in femtosecond laser cataract surgery to aspirate laser-softened and fragmented lenses without the use of ultrasound. In this initial clinical evaluation of the handpiece, 50 patients underwent femtosecond laser cataract surgery the 1.8mm MICS wound was opened 2.4 mm . The femto laser was used in a dice pattern to crack the lens and facilitate aspiration, and the new phaco handpiece was used for aspiration.
In the first 50 eyes, the handpiece has been easy to use with a 2.4mm incision. The handpiece effectively aspirated laser-treated cataracts of various densities. Aspiration of lenses without ultrasound can be expected to result in less trauma and endothelial cell loss compared with a standard handpiece. The study is ongoing, and the results will be updated. A video demonstration of use of the handpiece in femtosecond laser MICS will be presented.
The ZeroPhaco Femto handpiece has demonstrated ease of use and effectiveness for femtocataract surgery without ultrasound. Leaving a more prestine cornea quicker visual recovery than standard phaco after FemtoCataract surgery.
