Abstract Introduction: Lens luxation generally happens secondary to trauma and hereditary disorders into the vitreous body. However, spontaneous dislocation especially into the anterior chamber occurs rarely. We report an unusual case with spontaneous anterior dislocation of a posterior chamber intraocular lens (IOL) 4 years after cataract surgery. Case Presentation: A 42-year-old woman was referred to ophthalmology department with complaint of sudden onset blurring of vision in the left eye 4 years after cataract surgery. No history of trauma and systemic disorder was reported and no capsular fibrosis was found during eye examination. The patient underwent corneoscleral incision under general anesthesia and the IOL was extracted using a viscoelastic material. Conclusions: To our knowledge, this is the first reported case in the literature. This report may imply that IOL related factors could be considered for spontaneous dislocation of intraocular lenses.
