Purpose:
To report traumatic dislocation of a Visian Implantable Collamer Lens (ICL, STAAR Surgical Co) discovered on routine examination.
Methods:
A 26-year-old man was found to have ICL subluxation into the anterior chamber with pupillary capture on routine screening examination. The patient reported being punched near the left eye 2 weeks earlier. He noted mild blurry vision, no pain, and uncorrected distance visual acuity (UDVA) was 20/30, which was decreased from his baseline of 20/20 in the affected eye.
Results:
Surgical repositioning was performed under pupillary dilation without complication. Postoperatively, UDVA was 20/20(-2). Persistent pigment on the ICL, slight pupillary margin peaking, and anterior chamber inflammation were noted.
Conclusions:
Traumatic ICL dislocation may occur with minimal signs and symptoms. Education of patients about the necessity for examination after ocular trauma and need to wear eye protection during activities at high risk of ocular trauma are important.
