Extended Depth-of-Focus Technology in Intraocular Lenses

The extended depth-of-focus (EDF) intraocular lens (IOL) is an emerging technology that is designed to improve range of vision, especially at intermediate distances. In this short review, we describe the clinical performance of four emerging EDF IOL technologies: small aperture design, bioanalogic IOL, diffractive optics, and non-diffractive optical manipulations. The American Academy of Ophthalmology has generated a consensus statement for EDF IOLs that provided benchmarks and recommendations for classifying an implant as an EDF IOL and provided standardized testing criteria for evaluating performance.
