A Novel Surgical Technique for Transscleral Gore-Tex Suture-Assisted Rescue of Dislocated CZ70BD Intraocular Lenses Using 27-Gauge Instrumentation.

Abstract

To report a novel technique for refixation of dislocated CZ70BD intraocular lens (IOL). Vitrectomy trocars are placed along the horizontal meridian 5 mm apart. A CV-8 Gore-Tex suture is introduced through a bare sclerotomy into the midvitreous cavity. Under chandelier illumination, a 27 G broad platform forceps is threaded through the eyelet of the dislocated CZ70BD IOL. Using another pair of intraocular forceps, the free intraocular end of the Gore-Tex suture is fed to the broad platform forceps and externalized, thus repositioning the IOL. Particular attention is drawn to pass the suture in an over and under configuration to avoid IOL tilt. An identical procedure is repeated for the other eyelet if the IOL is completely dislocated. The 23 gauge or 25 gauge instruments should not be used for this technique because they do not fit loosely through the eyelets of the IOL. Three eyes were successfully operated on using this technique with at least 6 months of follow-up. There was significant improvement in best-corrected visual acuity after the operation. Postoperative IOL centration and alignment were satisfactory. The described surgical technique is effective for transscleral Gore-Tex-assisted refixation of dislocated CZ70BD IOL.
