摘　　要：景深延长(EDOF)型人工晶状体(IOL)是通过创建一个延长的单一焦点来增强景深,从而显著减少多焦点(MF)IOL植入术后产生的眩光、光晕及星芒等不良光现象。理想情况下,这类IOL能够在提高中距离视力和近距离视力的同时,尽量减少对远距离视力的影响。然而,景深延长带来的结果是对比敏感度和视觉质量的下降,因此需要进行权衡。未来研究的重点应是寻找最佳全程裸眼视力、最佳视觉质量和最小光现象之间的平衡,从而为白内障患者提供最优的视觉质量。本文笔者就EDOF型IOL的概念、分类、应用现状及未来展望进行评述。Extended depth of field(EDOF)intraocular len(IOL)can enhance depth of field by creating an extended single focal point,which significantly reduces glare,halos,and starlight after multifocal(MF)IOL implantation.Ideally,this type of IOL would improve middle and near vision while minimizing the impact on long distance vision.However,the result of lengthening depth of field is a decrease in contrast sensitivity and visual quality,so there are trade-offs to be made.The focus of future research should be to find the balance between the best overall naked eye vision,the best visual quality and the least light phenomena to provide the best visual quality for cataract patients.The concept,classification,application status and future prospects of EDOF IOL were reviewed.
