Abstract
Background: Intraocular lens (IOL) dislocation is a rare but serious postoperative complication of intraocular lens implantation, so far, there is no report describing late intraocular lens dislocation caused by a deformed haptic piercing through the iris. Case report: A 29-year-old male developed IOL dislocation one and a half years after IOL implantation in his right eye. The eye examination showed that haptic pierced the iris at 10 o'clock in his right eye, according to intraoperative exploration, the haptic was deformed and became less elastic, the patient underwent the surgery of IOL reposition for various factors, but finally did not achieve a satisfactory outcome. Conclusion: Late IOL dislocation followed by haptic deformation is difficult to detect unless there are serious complications. When the position of IOL haptics is not in a plane with its optical surface, it should be highly vigilant that the function of the haptics may be abnormal. IOL replacement should be performed as soon as possible for the IOL dislocation caused by the loss of haptic tension.
