Intraocular lens replacement: advantages of a bimanual technique with preset endoillumination

Performing a vitrectomy using a bimanual technique with a preset light inserted in the inferonasal quadrant of the eye leaves both hands free to grasp an intraocular lens (IOL) completely dislocated into the vitreous cavity. Two additional scleral grooves with flaps (surgeon's view) at the 2:30 and 8:30 o'clock positions (right eye) or at the 3:30 and 9:30 o'clock positions (left eye) allow the haptics to be guided to the desired positions in the ciliary sulcus. This technique allows permanent, controllable relocation of the IOL. The haptics of the IOL can be visualized while the suture is placed, and the IOL finally rests near the horizontal meridian, away from the corneoscleral wound.
