title: Treatment of negative dysphotopsia with supplementary implantation of a sulcus-fixated intraocular lens.
abstract: OBJECTIVE
  Our aim was to evaluate the resolution of negative dysphotopsia after supplementary implantation of a sulcus-fixated intraocular lens (IOL).
  
  
  METHODS
  This was a retrospective case series. Patients with severe negative dysphotopsia were treated with supplementary implantation of the Rayner Sulcoflex Aspheric (653 L) IOL. Primary outcome measurements were subjectively reported complaints of dysphotopsia, best corrected distance visual acuity (CDVA), iris-IOL distance, anterior chamber depth (ACD) and volume (ACV), angle opening distance and trabecular-iris space area at 500 and 750 μm.
  
  
  RESULTS
  A Rayner Sulcoflex IOL was implanted in seven patients (nine eyes) with negative dysphotopsias. Symptoms resolved completely in six eyes, partially in one eye and remained unchanged in two eyes. We did not find any significant changes in CDVA. Angle opening distance, ACD, ACV and iris-IOL distance reduced significantly after Sulcoflex IOL implantation.
  
  
  CONCLUSIONS
  Supplementary implantation of a Sulcoflex IOL can successfully treat negative dysphotopsia. The decrease in anterior segment dimensions in combination with the displacement of light rays by the rounded edges of a Sulcoflex IOL may contribute to the resolution of symptoms.
