To summarize the literature on dysphotopsia, focusing on strategies for management and prevention.
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.
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.
总结关于视幻觉的文献，重点关注其管理和预防策略。
临床研究和光线追踪图增进了我们对阳性和阴性视幻觉危险因素的理解。本文回顾了诸如背驮式人工晶状体、反向光学捕获、钕:钇铝石榴石晶状体切开术和人工晶状体置换等知名的管理和预防策略，以及诸如人工晶状体植入的颞下途径、“囊袋内鼻侧光学截断”和新型人工晶状体设计植入等新策略。
已知许多患者在白内障手术后会出现阳性和阴性视幻觉。鉴于视幻觉患者体验具有主观性且病因多因素，对其进行研究带来了诸多挑战，但这些挑战也催生了关于视幻觉的新理论和新观点。更好地理解现有的治疗和预防方法可以改善对视幻觉的管理并提高患者满意度。
