Abstract

The previously reported repositioning methods have been known to be very difficult to be performed. A new external knotting technique was performed to reposition the dislocated intraocular lenses (IOLs). After 3-port vitrectomy, a 30 gauge injecting needle tip into which the thread end of a 10-0 polypropylene was put, was introduced into the vitreous cavity through the ciliary sulcus to make a loop having an external knot. After one haptic of the IOL was engaged into the loop, the thread was pulled back and tied to make a knot. After holding and pulling the haptic of the IOL with the intraocular forceps for proper position of the knot. Then it was sutured and fixed in sclera. The IOLs were kept in central position without complications. The final visual outcome was 0.8 and 0.3 respectively. This method might be safe and easy to correct the dislocated IOL.
