Purpose :

Present a case of dislocation of an Implantable Collamer Lens (ICL) that occurs after blunt trauma and review the published literature on this topic.

Methods :

Case report and literature review using PubMed.

Results :

A 44 year-old male presented to the emergency department with sudden onset of blurry vision after blunt trauma to the left eye. Three years prior, he had undergone bilateral ICL placement for high myopia. On examination, the superotemporal haptic was noted to be dislocated into the anterior chamber, but there was no endothelial touch by the dislocated lens. The patient had an associated hyphema that was medically managed, and 2 weeks after the injury, the patient underwent ICL repositioning. A review of the literature was performed and five previous cases of ICL dislocation were identified. Three of these occurred after blunt trauma. One of these cases was associated with endothelial touch and decompensation and eventually required a descement’s stripping endothelial keratoplasty (DSAEK).

Conclusion :

Dislocation of ICLs after blunt trauma is a rare but important potential sequela of the procedure and can lead to corneal decompensation if there is lens-endothelial touch. All patients who suffer blunt dislocation of ICL should be followed long-term after repositioning for signs of endothelial loss and dysfunction.
