Episode 16: Intraoperative Aberrometry
This patient has a dense cataract, low ocular rigidity and unreliable preoperative biometry. The use of a high flow rate of 55 cc/min* to remove nuclear segments, wavefront aberrometry, and methods to prevent contact of the IOL with the endothelium during the late stages of the procedure are demonstrated.
*Note that the OR technician was asked to set the aspiration flow rate (AFR) at 50 cc/min, but instead selected 55 cc/min. This small (10%) difference in AFR was of course insignificant.
