Unforeseen challenge: bilateral, spontaneous, symmetrical displacement of toric implantable collamer lens: case report

Introduction: The phakic intraocular lenses represent a significant advancement in refractive correction particularly in patients for whom conventional procedures such as laser in situ keratomileusis (LASIK) are contraindicated. To our knowledge, although studies have extensively documented the occurrence and management of implantable collamer lens (ICL) rotation, spontaneous displacement of the ICL has not yet been documented. In this article, we present an interesting case of bilateral ICL displacement. Patient and Clinical Findings: After undergoing bilateral ICL surgery, the patient presented with blurring of vision the next day. On examination, there was symmetrical bilateral displacement of the ICL despite having implanted the maximum size of this lens. Diagnosis, Intervention, and Outcomes: After discussion and analysis, a bilateral explantation of the ICL was performed. Conclusions: Despite taking into consideration all the essential anterior segment parameters for ICL size calculation, there can still be a possibility of ICL displacement.
