A 64-year-old man had phacoemulsification in both eyes. In January 1998, an Allergan SI-30NB silicone intraocular lens (IOL) with a 6.0 mm optic was implanted in the right eye. In April, an Alcon AcrySof MA60BN acrylic IOL with a 6.0 mm optic was implanted in the left eye. The following October, the patient experienced visual discomfort in the left eye. Two superior radial minikeratotomies were performed. The patient continued to have visual discomfort and the next month, a topographic ablation was performed in the same eye. In January 2000, the left IOL was replaced with a 5.5 mm Allergan SI-55NB silicone IOL. Visual impairment resolved 1 day after surgery.
