Bilateral intraocular foreign bodies simulating crystalline lens. 
To report a case of large bilateral intraocular foreign bodies mistaken for crystalline lens on computed tomography (CT).  Case report.  A 24-year-old man was referred after bilateral open globe repair following a motor vehicle accident.  Preoperatively, the CT scan had been read as "Right eye posteriorly dislocated lens.  No evidence of foreign bodies."  The patient underwent left eye cataract extraction with removal of a 7 x 5 x 5 mm piece of glass buried in the crystalline lens.  The patient subsequently underwent right eye pars plana vitrectomy, removal of another piece of glass measuring 6 x 5 x 5 mm, retinal detachment surgery, and corneal grafting.  Current safety standards require auto glass to fracture into pieces of a specific size to minimize laceration and missile injury.  These pieces of glass may have a shape and size similar to the crystalline lens but have higher radiodensity on CT scan.
