Modified technique of haptic externalization for scleral fixation of dislocated posterior chamber lens implants - 03/09/11

PURPOSE: To describe a modified technique of haptic externalization during repositioning of dislocated posterior chamber lens implants, which facilitates placement of scleral fixation sutures around the haptic for implant stabilization.
METHODS: We describe a technique of repositioning a dislocated posterior chamber implant with scleral fixation sutures, which uses a small, clear corneal incision for externalization of the haptic. After a loop of 10–0 Prolene suture (Ethicon, Inc., Somerville, New Jersey) is placed around the externalized haptic, the sutures are retrieved through a sclerotomy 1.0 mm posterior to the limbus. The haptic is reimplanted into the ciliary sulcus. A separate scleral fixation bite closes the sclerotomy, and it is tied to the 10–0 Prolene sutures looped around the haptic.
RESULTS: The dislocated implant was stable and fixated in good position 5 months after surgery using this technique.
CONCLUSION: This externalization technique minimizes the extensive intraocular manipulations necessary to create a suture loop around a haptic of a dislocated implant. The clear corneal incision allows for clear visualization during externalization of the haptic.
