Pseudophakic dysphotopsia is an optical phenomenon that patients experience as a crescent-shaped shadow in the temporal peripheral visual fieldDr Olesen noted that pseudophakic dysphotopsia is an optical phenomenon that patients experience as a crescent-shaped shadow in the temporal peripheral visual field. It is mostly transient, but can be persistent and bothersome in up to 1% of pseudophakic eyes. One theory regarding its cause is that it results from a splitting of oblique rays of light at a gap between the optic’s edge and the capsulorhexis edge. That is supported by the observation that such a gap is almost invariably present in eyes with the condition. Several techniques have been shown to be effective in treating or preventing the condition. They include placing the primary IOL in the sulcus, positioning the optic in front of the anterior capsule, known as optic capture, and the use of specially designed IOLs with capsule capturing optic edges. He explained that he and his associates chose the Sulcoflex option in these patients because it affords the twofold option of correcting both residual ametropia as well as negative dysphotopsia in eyes where it occurs.
