ABSTRACT: We report a case of negative dysphotopsia in the left eye of a 56-year-old patient three months after uneventful bilateral phacoemulsification and implantation of a Crystalens® intraocular lens (Bausch and Lomb®) placed in the capsular bag. Three months postoperatively, the patient described visual field loss in the inferior temporal quadrant in the left eye under low light conditions. Anterior capsulorhexis was eccentric, allowing the inferior temporal optic edge to move forward, producing late asymmetric vault of the lens.
One month later, when the equatorial diameter of the capsular bag decreased, we pushed the inferior temporary hinge backwards so that the lens moved back into the correct position.
Six months after relocation, the lens position remained stable and negative dysphotopsia was absent. This case shows Crystalens Z syndrome as a new etiology of negative dysphotopsia, and a successful novel treatment in a patient without capsular fibrosis.
