Intraocular lens-blocking technique for intraocular foreign body removal

Abstract

The aim of this study was to describe a novel technique for intraocular foreign body (IOFB) removal. Phacoemulsification was performed in all patients, followed by a complete microincision vitrectomy to free all tissues surrounding the IOFB. A three-piece intraocular lens (IOL) was placed in the capsular bag, and an opening was made in the upper center of the capsule. The IOFB was removed and lifted to the anterior chamber through the capsular opening and IOL edge. The IOFB was confined to the anterior chamber by the IOL, and then easily extracted through the main corneal incision. The technique was adopted in six eyes of six patients. All IOFBs were removed successfully in all patients without intraoperative or postoperative complications. The IOL-blocking technique is a useful approach for IOFB removal.

Keywords: Intraocular foreign body; intraocular lens-blocking; posterior capsulotomy.

Schematic diagrams of the intraocular lens-blocking technique. (a) Combined vitrectomy, phacoemulsification, and IOL implantation were performed. The anterior chamber was filled with viscoelastic. (b) Posterior capsulotomy was performed with a vitrectomy probe. The IOFB was removed using intraocular forceps. (c) The IOFB was lifted to the anterior chamber through the capsular opening and IOL edge, with the aid of an iris spatula and intraocular forceps. (d) The IOFB was confined to the anterior chamber by the IOL and could easily be extracted through the main corneal incision

Intraoperative views of intraocular lens-blocking technique. (a) Combined vitrectomy, phacoemulsification, and IOL implantation were performed, and an opening was made in the upper center of the capsule. (b) The IOFB was removed using intraocular forceps. (c) The IOFB was lifted to the anterior chamber through the capsular opening and IOL edge, with the aid of an iris spatula and intraocular forceps. The capsular opening remained intact during this process. (d) The IOFB was confined to the anterior chamber by the IOL. (e) The IOFB was easily extracted through the main corneal incision using the forceps. (f) The size of the foreign body was approximately 4 × 2 mm
