NA, not applicable.

*Patient 1 had the entry wound repaired and an unsuccessful attempt made at IOFB removal made at an outlying facility via pars plana vitrectomy approximately 24 hours before our described external magnet extraction surgery. Preoperative visual acuity reported was the day after the initial surgical wound repair and unsuccessful vitrectomy, Findings at presentation were present hours after the injury—before any surgical intervention was undertaken, and lens status was both before the initial surgery and before our subsequent surgery.

†Antibiotics at time of IOFB removal.
