Dysphotopsia a multifaceted optic phenomenonHu, Jenny; Sella, Ruti; Afshari, Natalie A.Current Opinion in Ophthalmology: January 2018 - Volume 29 - Issue 1 - p 61–68 doi: 10.1097/ICU.0000000000000447 CATARACT SURGERY AND LENS IMPLANTATION: Edited by Natalie A. Afshari Buy Abstract Author InformationAuthors Article MetricsMetrics Purpose of review To summarize the literature on dysphotopsia, focusing on strategies for management and prevention. Recent findings Clinical studies and ray-tracing diagrams have improved our understanding of the risk factors for positive and negative dysphotopsiae. Well known management and prevention strategies such as piggyback IOL, reverse optic capture, Nd:YAG capsulotomy, and IOL exchange are reviewed, as well as newer strategies such as the infertemporal approach to IOL implantation, ‘in-the-bag nasal optic truncation’ and new IOL design implantation, and new IOL design. Summary Positive and negative dysphotopsiae are known to occur in a number of patients after cataract surgery. Although studying dysphotopsiae has provided many challenges given its subjective patient experience and its multifactorial cause, these same challenges have generated new theories and ideas regarding dysphotopsiae. A better understanding of the available methods for treatment and prevention can improve management of dysphotopsiae and patient satisfaction.
