To report traumatic injury of a patient implanted with Visian Implantable Collamer (ICL) (STAAR Surgical) lenses.


A 31-year-old man underwent bilateral implantation of Visian ICLs in 2006. Eight months postoperatively, the patient was serving in a combat zone and sustained blunt and fragmentation injuries from a grenade explosion. He was wearing full battle gear, which included ballistic-tested sunglasses, at the time of the assault.


Large intraorbital foreign bodies and globe trauma were identified as a result of the grenade explosion. Visual acuity was unaffected and the phakic intraocular lenses remained stable.


This first report of combat trauma in a patient implanted with bilateral phakic ICLs emphasizes the importance of eye protection. Further study of the stability and cataract formation rates in eyes that sustain blunt trauma after ICL implantation is needed.
