Oscillopsia associated with pseudoaccommodation in pseudophakia.

Oscillopsia associated with near fixation after multifocal intraocular lens (IOL) implantation has not been fully recognized. A 46-year-old woman presented with shaking of vision in both eyes during near fixation after uneventful implantation of a single-piece multifocal posterior chamber IOL in both eyes. There was no sign of zonular weakness in either eye before or during cataract surgery, and the postoperative course was uneventful. Visual acuity was 20/25 in both eyes without correction. There was no IOL oscillation with distant fixation; however, when she changed her focus from a distant to a near object, the IOLs started to oscillate in both eyes, which was assumed to be the cause of her oscillopsia. On cycloplegia, there was no IOL oscillation either with distant or near fixation. A rare cause of oscillopsia associated with pseudoaccommodation after IOL implantation should be recognized.
