A Case of Accidental Inverted Phakic Intraocular Lens Implantation

A patient with high myopia and astigmatism inadvertently received an inversely implanted Implantable Collamer Lens (ICL) in her left eye. The Best-Corrected Visual Acuity (BCVA) decreased in the left eye, and the patient developed high Intraocular Pressure (IOP) secondary to angle closure glaucoma. The anterior chamber was deep centrally and shallow with iridocorneal touch peripherally. After re-inversion of the ICL, the IOP returned to normal, the anterior chamber deepened and visual acuity improved. Inverse ICL implantation is a rare complication that can be mitigated by preventive measures, intraoperative recognition or early postoperative management. To our knowledge, this is the first reported case of inadvertent placement of an inverted ICL that remained within the eye for 5 days.
