The development of phacoemulsification using ultrasonic energy by Charles Kelman, MD, transformed the way that we perform cataract surgery.
With Kelman’s innovations, we are now able to remove a 9 mm wide cataract via incisions that are about 2 mm in size. The ultrasonic energy is effective at breaking up and emulsifying the cataract, but it can also have side effects within the eye.
The ultrasonic vibrations are a form of mechanical energy in which the phaco needle travels back and forth or circumferentially with longitudinal or torsional movement, respectively. (Read more...)
