Extended Depth of Focus IOLs: The Next Chapter in Refractive Technology?


resbyopia-correcting intraocular lenses (IOLs) have revolutionized refractive cataract surgery as evolution in materials and optical designs allowed for a better balance of functionality while reducing unwanted symptoms. Presbyopia-correcting IOLs have become a focus of attention in IOL selection discussions with patients due to the increasing number of activities that require near and intermediate vision in our modern world, such as tablets, smart phones, and computers. Numerous IOL platforms have been designed to extend the range of focus as “presbyopia-correcting IOL” options, and three main categories can be identified: those including multifocality (functional bifocal and trifocal IOLs), accommodative or pseudoaccommodative IOLs, and extended depth of focus (EDF) IOLs. Regardless of the optical design or strategy chosen to achieve relative spectacle independence, a certain degree of visual compromise can still be anticipated.
