Dislocation of implantable collamer lens following blunt trauma

to present the signs, symptoms and management of two cases of traumatic dislocation of implantable collamer lens (ICL) after direct blunt trauma.

at presentation, we noted diffuse conjunctival hyperemia, and clear cornea in the right eye of the first patient. The anterior chamber showed +2 pigmented cells, a distorted, nasally peaked pupil with one-foot plate in front of the iris. The second case had a dislocation of the inferonasal footplate into the anterior chamber without endothelial touch.

Dislocation of an implantable collamer lens (ICL) is rare but carries the risk of long-term complications, particularly after trauma. Ophthalmologists should identify dislocation and timely intervention can mitigate the risk of complications.ICL dislocation can be vision threatening.
