Double-knot transscleral suture fixation technique for displaced intraocular lenses

PURPOSE: To describe a simplified new technique for repositioning and attac hing a suture to the haptic of a displaced posterior chamber intraocular le ns (IOL), METHODS: We describe a double-knot technique for repositioning and transscl eral 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 r epositioned haptic of the TOL. A second knot ties the transscleral suture i n the scleral bed, stabilizing the haptic in the ciliary sulcus. RESULTS: In the case described, the IOL was stable and well positioned 2 mo nths after surgery. CONCLUSION: The double-knot technique for intraocular repositioning and tra nsscleral suture fixation of displaced posterior chamber IOLs reduces the e xtensive intraocular manipulation and scleral incisions required for IOL ex change and may reduce chronic irritation associated with iris fixation.
