Abstract

An 11-year-old boy was struck in the left eye with a mechanical pencil in a projectile manner. Initial examination under the operating microscope revealed a presumed partial-thickness corneal injury with a retained 8-mm long segment of graphite lead. After removal of the graphite segment, a full-thickness hole in the cornea was revealed under the lead shaft. The proposed mechanism of injury and unique presentation was initial full-thickness penetration followed by lead shaft retraction (likely due to eye rubbing) and then corneal stromal reentry with stromal lamellar dissection and fixation. Prompt removal of the foreign body, corneal laceration repair, and early cataract extraction resulted in postoperative 20/40 uncorrected visual acuity. Mechanical lead pencil injuries represent a unique mechanism of penetrating trauma.
