"Luggage-Tag" Suture Fixation of Partially Dislocated Intraocular Lenses

Abstract

There are many techniques for sulcus-suturing dislocated or partially dislocated intraocular lenses. Many involve passing suture or a knot around the end of the haptic before securing the suture to the sclera. However, in some patients, the tip of the dislocated haptic cannot be visualized. We describe a suturing method using vitrectomy techniques that was used in two patients when the end of the haptic could not be visualized. The technique involves passing an untied loop of double-armed suture under the haptic so that it emerges upward between the haptic and the optic. The loop of suture is regrasped from above the haptic and externalized. The free ends are passed through the loop in a manner analogous to a luggage tag, and the knot is secured. This technique may be useful in patients where the tip of the haptic cannot be visualized, or in patients requiring minimal manipulation of the intraocular lens.
