We describe a technique for knotting a suture to the haptic of a dislocated intraocular lens (IOL) through a sclerotomy site without removing an IOL in 4 patients. The suture was knotted to the haptic from outside the sclera. The remaining suture material was tied together and buried in the sclerotomy site. To prove that we could suture to the haptic safely, experiments were carried out using 4 scleral shells of donor eyes. No complications occurred, and good visual recovery was achieved. In this method, the haptic can be tied safely through the sclerotomy site and reduce the risk for knot-related complications. To our knowledge, this approach has not been reported.
