Abstract
PURPOSE: To describe a simplified new technique for repositioning and attaching a suture to the haptic of a displaced posterior chamber intraocular lens (IOL). METHODS: We describe a double-knot technique for repositioning and transscleral suture fixation of a subluxed posterior chamber IOL after penetrating keratoplasty. Two 10-0 Prolene transscleral sutures on straight needles are passed around the IOL haptic, tied extraocularly, and used to secure the repositioned haptic of the IOL. A second knot ties the transscleral suture in the scleral bed, stabilizing the haptic in the ciliary sulcus. RESULTS: In the case described, the IOL was stable and well positioned 2 months after surgery. CONCLUSION: The double-knot technique for intraocular repositioning and transscleral suture fixation of displaced posterior chamber IOLs reduces the extensive intraocular manipulation and scleral incisions required for IOL exchange and may reduce chronic irritation associated with iris fixation.
