Zusammenfassung: | Novel techniques and instrumentation are disclosed for repositioning an intraocular lens (IOL) that becomes dislocated, such as following cataract surgery. In some methods, a trocar or sheath is placed through the eye wall near the ciliary body until a distal tip of the instrument is near the intraocular target to be moved. A clip or other engagement structure at the end of the instrument is manipulated to engage a portion of the IOL, such as a haptic, using various disclosed engagement mechanisms. The instrument is then manipulated to reposition the target to a desired position. In some cases, sutures are attached to the target or to the clip and then secured on the external surface of the eye to secure the target in the desired position. |
