To perform extracapsular cataract extraction safely the surgeon must know the orientation of the aspiration port of the irrigation/aspiration handpiece at all times. I have modified a commercially available irrigation/aspiration handpiece to allow visual and tactile orientation of the aspiration port even when it is obscured by iris, blood, or cortex.
