Surgical Management of an Externally Protruding, Perforating Intraocular Foreign Body.

Ru-ik Chee Felix Y. Chau In this case of a perforating eye injury by a 2-inch-long nail that went through the cornea, lens, and posterior eye wall, the authors describe a combined external, anterior, and posterior segment surgical approach that resulted in safe and successful removal of the foreign body. Initial external trimming of the protruding nail facilitated the use of a noncontact viewing system. Combined limbal and pars plana placement of the vitrectomy cannulas optimized access to both anterior and posterior intraocular structures. Most importantly, careful removal of potential sources of foreign body adhesion to intraocular structures prior to extraction likely increased the likelihood for a successful clinical outcome. Care was taken to remove as much of the vitreous as possible and to keep the eye formed. The patient recovered 20/25+2 vision with aphakic correction.
