Novel approach in the treatment of intravitreal foreign body and traumatic cataract: three case reports

We present a novel surgical technique of simultaneous traumatic cataract extraction, internal magnet removal of the intraocular foreign body, and implantation of a posterior chamber intraocular lens in the eyes of three patients with traumatic cataract and ferrous intraocular foreign body retained in the anterior part of the vitreous body. Primary corneal wound repair, cataract extraction, anterior vitrectomy, removal of the intraocular foreign body through the corneoscleral limbal incision by using intraocular magnet, and intraocular lens implantation were performed. All intraocular foreign bodies and corneal entry sites were not larger than 3 mm. After a median follow-up of 13.6 months (range, 9-21 months), visual acuity ranged from 0.6 to 1.0. There were no early or late postoperative complications. According to our experience, an anterior approach in the surgical technique of simultaneous cataract extraction, intraocular foreign body extraction and implantation of a intraocular lens in the capsular bag is possible in selected patients with intraocular foreign bodies positioned in the anterior vitreous, behind the lens, with no associated retinal pathology.
