Background: To explore minimal surgery in selected patients with intravitreal foreign body (IVFD) and traumatic cataract.\nMethods: Twelve eyes of 12 patients with small ferrous IVFD and traumatic cataract without endophthalmitis,\nretinal injury and secondary glaucoma, between September 2015 and March 2017 were retrospectively analyzed.\nPrimary removal of IVFD was performed by external magnetic extraction through the pars plana incision.\nSecondary removal of traumatic cataract by phacoemulsification and intraocular lens (IOL) implantation with or\nwithout anterior vitrectomy were performed. Patients were followed up at 1 day, 1 week, 1 month, 3 months,\n6 months and 12 months after surgery.\nResults: All patients were male with a mean age of 32 years old. All IVFDs were successfully removed without\nretinal injury. Two to 6 months later, the traumatic cataract was successfully removed by phacoemulsification\ncombined with IOL implantation in the capsule bag in 10 patients. Anterior vitrectomy was implied in 2 patients\nwith large posterior capsule rupture, and the IOLs were placed in the ciliary sulcus. Best-corrected visual acuity\nranged from hand movement to 20/100 before surgery and improved ranging from 20/32 to 20/20 at the final\nfollow-up. The IOLs were well centered. Complications such as secondary glaucoma, endophthalmitis and retinal\ndetachment were not found.\nConclusions: Primary removal of small ferrous IVFD by external magnetic extraction followed by secondary\ncataract removal and IOL implantation is an appropriate choice. Minimal surgery may obtain good visual\noutcome without complications in selected patients.
