Prechopping, Torsional Ultrasound, and Centration on the IOL
To ensure that an IOL is well centered with proper coverage of its rim, Dr. Robert Cionni uses a Capsulorhexis Marker (Mastel Precision, Inc., Rapid City, SD) at the start of each case. The marking ring is placed on the cornea with the crosshairs centered in the Purkinje image within the undilated pupil. After pre-chopping the nucleus, the lens is emulsified with OZil Intelligent Phaco (Alcon, Fort Worth, TX) enabled torsional ultrasound.
