Cataract surgical problem

摘要

A lively, 74-year-old woman was referred for management of negative dysphotopsia involving the right eye. Her history shows that she had uncomplicated cataract extraction augmented by femtosecond laser anterior capsulotomy. In accord with previous low-hyperopic laser in situ keratomileusis (LASIK) performed 15 years earlier, a spherical single-piece acrylic IOL (Alcon SN60AT) was selected and centered in the capsular bag. Unfortunately, despite anatomically "perfect" surgery, the patient was highly symptomatic with unrelenting negative dysphotopsia. Six months later, under the care of another ophthalmologist, she had the original IOL exchanged for a single-piece Collamer plate-haptic IOL (Staar CC4204A) (Figure 1). Now, an additional year after the latest surgery, she remains debilitated by unchanged negative dysphotopsia symptoms.
