Ultrasound cycloplasty for uncontrolled intraocular pressure after glaucoma surgery
After draping patient for surgery, the retrobulbar injection of 3.5 ml of 2% lidocaine hydrochloride injection was performed to achieve anesthesia. Probe inserted in the coupling cone was fixated on the patient’s eye, then the negative pressure was started and the system detection was finished. The cavity created among the eye, the cone, and the probe was filled with 0.9% sodium chloride solution at room temperature during the entire procedure. Each sector was treated for 8 seconds and there was a pause for 20 seconds between sectors. The probe and coupling cone was maintained firmly by clinician in the optimal position during the entire procedure. The probe was rotated after the treatment of 6 sectors. After treatment, the probe was pulled out, and the negative pressure was automatically released, then the cone was removed.
