Abstract
INTRODUCTION AND IMPORTANCE: Intraocular lens (IOL) implantation after cataract surgery is routine procedure. Traumatic dislocation of the posterior chamber IOL into the subconjunctival space following blunt ocular trauma is rare and it is considered an ophthalmic emergency. CASE PRESENTATION: We present a case of a 71-year-old male that presented to our institution with traumatic dislocation of a posterior chamber IOL into the superior-nasal subconjunctival space following blunt trauma to his left eye after an accidental fall on his head. DISCUSSION: Trauma in a pseduphakic eye can be devastating. Early recognition and treatment of IOL dislocation are of paramount importance to prevent further damage and infections. Half ring sign (Psudophacocele) recognition help in identifying and localizing the dislocated IOL in subconjunctival space. CONCLUSION: Traumatic dislocation of posterior chamber IOLs have been rarely reported in the literature. Nevertheless, it could happen years after implantation.
