Posterior-segment intraocular foreign body removal preserving intraocular lens – A novel technique

Abstract

We report a case presenting with corneal tear with vitreous incarceration with intraocular foreign body (IOFB) impacted in the retina following hammer chisel injury. Following anterior-segment repair and anterior vitrectomy, standard 23G pars plana vitrectomy was performed, and impacted foreign body was released. Metallic IOFB was retrieved with the help of 23G magnet just behind the intraocular lens (IOL) following which serrated forceps was used for grasping. 23G magnet was now used via limbal incision to retrieve the foreign body in the anterior chamber through the preexisting posterior capsular rent. After stabilization of the anterior chamber with viscoelastic injection, IOFB extraction was done with the help of serrated forceps by extending the side port. This surgical technique appears to be safe and effective for retrieving fragile, slippery, large IOFB without explanting the IOL and extension of scleral incision with prompt recovery.
