A novel surgical technique for transscleral Gore-Tex suture-assisted rescue of dislocated CZ70BD intraocular lenses using 27-gauge instrumentation.

BACKGROUND AND OBJECTIVE

To report a novel technique for refixation of dislocated CZ70BD intraocular lens (IOL).

METHODS

Vitrectomy trocars are placed along the horizontal meridian 5mm apart. A CV-8 Gore-Tex suture is introduced through a bare sclerotomy into the mid vitreous cavity. Under chandelier illumination, a 27G 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 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 or 25 gauge instruments should not be used for this technique as they do not fit loosely through the eyelets of the IOL.

RESULTS

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 (BCVA) after the operation. Postoperative IOL centration and alignment were satisfactory.

CONCLUSION

The described surgical technique is effective for transscleral Gore-Tex-assisted refixation of dislocated CZ70BD IOL.
