Fig. 22. Another option is to remove the anterior and posterior lens capsule with a suction-cutting instrument. A. The lens nucleus is aspirated after the anterior capsule is removed. B. A posterior capsulotomy. The cutting port is rotated so that it faces upward and the opening is enlarged, leaving a posterior rim that is slightly wider than the anterior rim of the capsule. Both the suction pressure and the cutting speed are reduced during this maneuver. C. The anterior and posterior capsular flaps seal together, forming a shelf to provide guidance and support for sulcus fixation of a secondary posterior chamber lens if needed.
