Determination of refractive error and visual acuity after implantation of multifocal or extended depth of focus lenses

There are many factors that can affect the postoperative satisfaction of patients after implantation of intraocular lenses with extended depth of focus (EDoF) and multifocal lenses (e.g., photic phenomena, postoperative complications and the presence of dry eye symptoms); however, achieving the target refraction should also be considered an important factor in the satisfaction. This article highlights the pitfalls in determining the refractive error in patients with a multifocal or EDoF lens and how uncorrected and corrected visual acuity can impact patient satisfaction.
