title: Isolated dislocation of a supplementary sulcus pseudophakic intraocular lens.
abstract: We report the case of a woman with pseudoexfoliation who presented with a hyperopic refractive surprise and uncontrolled intraocular pressure (IOP) following cataract surgery and in-the-bag intraocular lens (IOL) implantation in the left eye. Trabeculectomy was performed, and a supplementary (piggyback) sulcus IOL was inserted. At 5 years, the uncorrected distance visual acuity (UDVA) was 20/16 and the IOP was less than 21 mm Hg. Following head trauma, the patient experienced blurred vision. The UDVA was 20/125, correcting to 20/25 with +3.00 -0.75 × 105. The IOL in the capsular bag was not dislocated, but the sulcus IOL was not in the posterior chamber; it was found by ultrasound in the temporal anterior vitreous gel. At-risk patients having supplementary IOL insertion should be warned of this possible late problem.
