Disclosed herein is an apparatus selectively attachable to an ultrasonic device to disrupt target cells from underlying tissue for treatment of an ocular condition, including a shaft, a coupling portion at an end of the shaft, and a cell disrupting end extending from a distal portion of the shaft. The shaft has a longitudinal axis and a first diameter. The coupling portion includes a connector portion and a hub configured to selectively couple to the ultrasonic device and impart ultrasonic vibration to the shaft. The cell disrupting end is solid and has a second diameter and a smooth, continuous, curved shape.
