A rare mechanism of subconjunctival dislocation of anterior chamber intraocular lens after blunt ocular trauma

Abstract

Introduction Dislocation of intraocular lens (IOL) after ocular trauma is an emergency situation requiring prompt surgery. Dislocation of IOL into the subconjunctival space or pseudophacocoele is a rare event after blunt ocular trauma.

Case outline We report a case of a pseudophakic patient with a dislocation of the anterior chamber IOL (ACIOL) into subconjunctival space following blunt trauma to the right eye. A 76-year-old man presented with ACIOL dislocation into subconjunctival space, adapted old scleral wound and preserved corneal integrity. Fifteen years previously he suffered right eye globe rupture after blunt trauma, which was surgically closed and ACIOL was inserted.

Conclusion This case highlights a rare mechanism of ACIOL dislocation into subconjunctival space following blunt ocular trauma with preserved corneal integrity and adapted old scleral wound. In cases of post-traumatic aphakia, IOL dislocation into the subconjunctival space should be suspected.
