Dr. Ahmed M. Habib removes a large piece of glass from inside a patient’s eye using a bimanual or two-handed technique. According to the Academy’s EyeWiki, when an internal approach to intraocular foreign body (IOFB) removal is required, a standard 3-port vitrectomy is performed. The sclerotomy incision should avoid the area of the entry wound to prevent further damage to intraocular tissues if any incarceration is suspected. The first goal of the vitrectomy is to remove any adhesions of the IOFB, to avoid any pull on the retina. Once the foreign body is free from all the adhesions, it can be removed with forceps or a magnet. Before removing the foreign body, peripheral examination of the retina and removal of the peripheral vitreous should be performed to avoid any traction while removing the foreign body through the sclerotomy. If the IOFB is larger than the sclerotomy site, enlargement of the sclerotomy in a circumferential direction may be necessary.
