Management of Negative Dysphotopsia following Cataract Surgery

摘要

?Purpose?To evaluate the benefit of various surgical interventions to treat negative dysphotopsia following uncomplicated cataract surgery.?Methods?Restrospective review of patients with persistent pseudophakic negative dysphotopsia following uncomplicated cataract surgery. Negative dysphotopsia defined as: subjective complaint of dark temporal crescent that persisted for 1 month post-operatively. Patient were treated with either Neodymium:YAG (Nd:YAG) laser anterior capsulectomy or in-the-bag intraocular lens (IOL) exchange. Primary outcome was partial or complete resolution of negative dysphotopsia symptoms 3 months postoperatively.?Results?8 patients with negative dysphotopsia had surgical treatment. 3 of 4 patients who had in-the-bag IOL exchange had partial or complete resolution of symptoms by 6 months. 3 of 5 patients who had Nd:YAG laser anterior capsulectomy had partial or complete resolution of symptoms by 3 months.?Conclusions?Modification of the anterior capsule-IOL relationship is important for the resolution of negative dysphotopsia symtoms. No one treatment method yielded consistent results, suggesting a multifactorial etiology of negative dysphotopsia. ?View OriginalDownload Slide?Table 1. Surgical Method and Outcomes.?Table 1.
